Dell inspiron 1520 review

Dell inspiron 1525 review

The Dell Inspiron 1520 under review here is the latest 15.4” in an ever-growing succession of what can be categorized as “consumer mainstream” notebooks offered by Dell’s Home & Home Office division. Since the release of the 1520, Dell has also made available a very similar machine, the Vostro 1500, which can be purchased from the Small Business site. Unlike the Inspiron 1520, which can be configured with any one of eight different colors, the Vostro 1500 is solid black. The Vostro also provides a Windows XP option, which is unavailable in the Inspiron 1520 battery.

It should also be noted, for the benefit of anyone who is somewhat new to this website, that there is plenty of additional information on the 1520, including an excellent full-featured review by someone who actually purchased the 1520, as well as a side-by-side comparison of the 1520 and the HP dv6000t battery; this comparison includes a video that is definitely worth watching for anyone considering the Inspiron 1520, the HP dv6500t or any other 15.4” consumer notebook.

Initial Impressions

This Inspiron 1520 battery weighs about six and a half pounds and is considered a mainstream consumer notebook. Though Dell allows customization of the lid in up to eight different colors, our model has a conservative looking black lid. Because of that our machine lacks some of the consumer flair a “Flamingo Pink” lid would have offered. Nonetheless, my first impressions had to do with a couple of things that distinguish the 1520 from its predecessors:

The overall look is very different, in a good way.
The hardware, particularly in the form of graphics processing, will allow the 1520 to perform about as well as any notebook on the market, with the exception of outlandishly expensive gaming machines that lack any concessions with respect to size, battery life and cost.
These two characteristics are what make the 1520 such an impressive achievement. I actually briefly owned the previous Inspiron e1705 generation’s model, and reviewed the prior-generation e1405 thin-and-light notebook. I must say, the look of the current lineup is immeasurably more appealing. The old silver-and-white style always got me thinking of things like shag carpet and popcorn ceilings: sure, one can make a case for these innovations, just as one can make a case for thick white plastic trim around a notebook, but in the end (which usually comes within a matter of weeks if not months), the style grows tired, the initial promise hollow. The new Inspiron series design is cleaner, simpler and more tasteful. A cousin of the 1520, which shares its look, is the AMD-based Inspiron 1521.

Purchasing Considerations

Though this notebook was sent by Dell GK479 for review purposes and not purchased, I wanted to touch on the above topic, simply because there is something of an art to purchasing a Dell consumer notebook. There are many decisions to make, and like all decisions, they carry with them the opportunity for regret or satisfaction. I heartily endorse this web site’s forums for a little glimpse into the thought, action and subsequent level of satisfaction of other buyers.

As of this writing, deliberately moving along the Dell purchasing highway results in:

An Inspiron 1520 with a fairly basic configuration, but one more than adequate for general media and office tasks, for just over $900.
A deluxe performance configuration, virtually identical to this review machine, for just over $1500.
These prices reflect no special discounts or coupons, just today’s standard upgrades and reductions, which are plainly available to anyone who orders a 1520 today. In any case, at the high end particularly, these prices strike me as very competitive, and a savvy shopper who finds coupons, buys their own memory and times the Dell marketing promotions can do better on price.

One thing I found interesting while configuring a couple of 1520s on the Dell laptop battery site was the price of a RAM upgrade from 2GB to 4GB: $850. Had I selected a higher-priced starting point, meaning a more full-figured set of warranty and support options, the cost of these 2 gigabytes of RAM would have moved away from the direction of a cool grand, but not by much. I saw no mention of this upgrade including a complimentary iPhone or round-trip flight to London, but it is there and available. That said, I would definitely opt for the T7300 CPU and the 8600M GT graphics included in this review model, if at all possible. While these enhancements will probably add three or four hundred dollars to the final price, they are well worth the cost and will almost certainly give the 1520 a longer useful life.

Design

As noted, I like the look of the Inspiron 1520 and see it as a vast improvement over the Inspiron e1505 battery, the 1520’s predecessor. However, one thing I’ll mention is that my own preference is the black lid of this review model because I find, in pictures at least, that the machines with colored lids have too much color for me. Two distinct colors, in this case silver and black, are just about right. I also like the aforementioned Vostro 1500, very similar to this 1520 and available at the Dell Small Business site, because of the all-black look, including a black keyboard, and the possibility of Windows XP. Though many won’t, I see a black keyboard and XP as decided advantages.

Also a welcome change is the placement and position of the keyboard and touchpad. The prior line of Inspirons featured a somewhat odd shaped keyboard that was set very close to the LCD, and a rather large touchpad placed in the middle of a vast sea of silver plastic. While this did allow the palm rests to accommodate even the most monstrous palms, the new Inspiron 1720 battery line, as represented by this review 1520, has a slightly smaller touchpad and a more centered keyboard; this redesign makes for more comfortable typing and touchpad operation, besides being more aesthetically harmonious.

Build

The Inspiron 1520 feels very solid. The only issue, which has been mentioned elsewhere, is the screen latch, which does have some play. Aside from this lack of a nice, snug fit, the latch did not bother me, and I found nothing in the build quality that would make me hesitant to purchase a 1520. Firm but gentle pushing and prodding revealed no flex or weakness.

Input and Output Ports

The Inspiron 1520 has the following ports selection:

(4) USB 2.0 Ports
Integrated 10/100 LAN and 56K Modem
IEEE 1394a
8-in-1 Card Reader
VGA Video Output and S-Video
Stereo In, Headphone/Speaker Out and Dual Digital Mics
ExpressCard 54mm Slot

Color and brightness were both good on the WSXGA glossy LCD. While I like and would myself choose this option, other resolutions are available: 1280×800 WXGA, in both glossy and non-glossy, and 1440×900, glossy only. This represents improved LCD variety and is a major selling point of the 1520; there is something for nearly everyone. Careful scrutiny revealed only one utterly trivial imperfection in the screen: an eighth of an inch or so of uneven backlighting at the bottom of the LCD, which was only visible when I looked very closely while running a screen saver with a dark background. There has been some discussion in this site’s forums about “grainy” LCDs in the 1520, but I detected none of this. However, I am admittedly not a good cohort for those studying LCD perfection; generally (but not always) I’m okay with the screens I use. Everest Home lists the screen as an SEC3350, a Seiko Epson manufactured LCD.

Graphics

The NVIDIA GeForce 8600M GT is currently among the cream of the crop in notebook GPUs. Athough RivaTuner indicated that the 8600m in the Inspiron 1520 had DDR3 memory, in reality it is DDR2, which may be dissapointing to some. All the same, it’s a powerful card and there were no graphics-related problems during my time with the 8600M. For those interested in gaming considerations, there is plenty of real-world information in this web site’s forums.

Sound

As always, or almost always, when discussing notebook sound: more than adequate for getting the gist, feel and intent of what’s being played, but definitely lacking in bass. Headphones or external speakers will provide a much more lifelike experience.

Multimedia Features

This 1520 came with a remote, snugly ensconced in the ExpressCard slot, as well as an array of physical media buttons on the front of the notebook. Both the built-in buttons and the remote worked as expected, forwarding and pausing and muting in accordance with my wishes.

Processor and Performance

Thanks to the very strong components, performance was always good, regardless of the stress put on system resources such as RAM and CPU. The new Santa Rosa platform coupled with an Intel T7300 CPU, together with a stronger GPU, outperformed my “old” T2400-based Dell Precision M65 by a wide margin on all benchmarks.

For prospective buyers, it may be worth adding that this review 1520’s configuration is worth considering if one is looking for excellent performance while keeping the price reasonably modest. The T7300 is the cheapest available CPU that comes with 4MB of Level 2 cache, the 8600M GT GPU will provide optimal graphics performance, and anything less than 2GB RAM will significantly hinder performance.

Keyboard and Touchpad

Dell Inspiron 1520 keyboard (view large image)

Keys are responsive and have good travel. Overall, I’d say Dell has done an excellent job with the 1520’s keyboard, both in terms of the feel and the new placement that doesn’t err northward the way the last-generation Inspirons did, especially the e1505 and Dell e1705 battery. Individual key placement makes sense, being more or less standard, and the half-height function keys are consistent with, and just as comfortable as, their larger brethren. The touchpad, which is smaller than that of the e1505, is eminently usable and did everything I expected of it with no discomfort or untoward behavior.

Laptop Battery Life

Under fairly heavy usage, e.g., a lot of hard drive activity, wireless going and the screen set to maximum brightness, I managed to run on the battery for almost three hours. Very light usage and a dim display, but wireless still running, yielded an additional hour or so. I expected a greater disparity, given that my usage for the two tests was at opposite ends of the spectrum, but I did have wireless enabled for the light-usage test, and both times seemed fairly strong for a machine with this power. With a little tweaking, I’m sure others could squeeze more life out of the 9-cell Dell FK890 battery.

Heat and Noise

The 1520 was remarkably quiet (virtually silent, in fact) the whole time I had it, and heat was never a problem. The bottom of the unit became a little warm after protracted heavy activity, but not unusually so.

Service and Support

I have used Dell support in the past and have always been satisfied, in the end, with the experience, but I had no reason to contact support regarding this 1520.

Software

Being a creature of habit, I removed most of the “trialware,” along with some other common programs I loathe, as soon as I received the notebook. I was barely paying attention while doing this, but the whole process for this review notebook seemed to go very quickly. There were no apparent software issues, though I do find myself longing for Windows XP whenever I use a Vista machine. The availability of XP is reason #2 for my seriously considering the Vostro 1500 if I were in the market for a high-powered 15.4” notebook at a reasonable price.

Conclusion

Much of what I found while using the Inspiron 1520 is consistent with (to the point of being almost identical to) what has been written elsewhere. There was really only one thing about this notebook that bothered me, my preference for the all black Vostro 1500 battery notwithstanding: the play in the screen latch mechanism when the notebook is shut. Is this a big deal? I would say no, not at all.

There are so many positives, including the overall build quality, and so much flexibility in terms of configuration, the 1520 would seem to make a lot of sense for a wide range of notebook users, and a little bit of latch looseness should not be a determining factor. There are many fine notebook deals in the Sunday ads, as well as online, but there is often something about these machines, such as the keyboard, the graphics or the resolution, that would make me reluctant to purchase one of them. The 1520, or the Vostro 1500, for that matter, can be configured just right. If I weren’t already happy with my two laptops and in no hurry to get a replacement, I’d definitely consider the Inspiron 1520 or its nearly identical sibling, the Vostro 1500.

Why laptop battery explode?

Why laptop battery explode?

Laptop battery is composing of enclosure, interface, cell and control circuit board, battery cell is responsible for supplying and storing the power of the laptop. Control circuit board with complex working principle and design, it controls the battery start and stop charging at proper time, control the discharge current reasonable, and it also take charge of showing the battery capacity and recycle charge times recording. When the battery in a high temperature or large current and other un-normal condition, it the control circuit board can protect the battery.

The OEM post in http://www.laptops-battery.co.uk/

The four suspicion of laptop battery explosion.

A, Battery cells interior short-circuit

The Latitude D620 battery cells has no protection function when meet large current, if single or multiple cells happen short-circuit situation, it will let cells discharge at high current. These current generate large quantity of heats will let the battery enhance the temperature, and then transfer to the other parts of laptop.

If the Latitude D600 battery enclosure is plastic material, it will deform or even get fired under high temperature, it is dangerous. The regular cells has experience strict test when out from factory, and the battery enclosure always adopt fireproof material and difficult to get fire. So the most possibility is involved with poor quality material for VGP-BPS2C VGP-BPS2 VGP-BPS5.

B, Battery cells connector wire short-circuit

The Dell Inspiron 6000 Battery, interior structure is too compact which leave opportunity for the cells. The wires in the middle are quite compact and close to the cells, if the skin of the cells and wires wore out, or the connect wires break off, then the cells will discharge at very high current and bring high temperature and cause fire final.

C, The control circuit invalidation

Sometimes, the control circuit will be invalidate for its protection part even it performed normal when use Sony NP-BG1, Canon BP-511,, when under full charge and un-normal, large current situation, the temperature will enhance and cause fire.

D Heat and abrupt incident

The laptop over heat or exterior liquid corrode, lightning strike or voltage un-normal will cause short-circuit.

Nec VersaPro VS-7, the Ultimate Netbook is Japanese.

Before going any further with our quick review of NEC’s latest VersaPro Netbook, I’d like to stress I have no interest whatsoever in Netbooks for Dell Inspiron 1300 battery,Dell Inspiron B130 battery. Today’s Netbooks are too thick and heavy to even be considered portable… And in Japan for a couple of bucks more you can get a Core 2 Duo capable PC with pretty much the same shape, size, and weight that provides WAY more potential than the average Netbook.

That said… I admit today for the first time Netbook trends have begun. I finally fell in love with one, behold the Nec VersaPro VS-7, an Atom powered Netbook that for once gives real meaning to the term ultra portability and powered with Apple Powerbook G4 battery Powerbook G4 12 battery Powerbook G4 17 battery.

The NEC VersaPro VS-7 is one of a kind with impressive numbers
- Intel Atom Z540 (1.84GHz)
- 64GB of SSD
- 15.8mm Thick
- 725g
- A body that resists pressures up to 150kg!

Granted the NEC VersaPro VS-7 is expensive, and costs twice as much as the average Netbook in Japan, but look again at the specifications… What other Netbooks are capable of matching these amazing numbers… Seriously, 725g and 15.8mm thick. Who can beat it? I think Sony  VGP-BPS2C VGP-BPS2 VGP-BPS5 can do this.

Not only is the VersaPro VS-7 is freaking light, slim, and robust, I’m amazed by its performance despite NEC’s choice of integrating an Intel GMA500 Video chipset… We all know GMA500 Netbooks don’t keep pace when it comes to watching high quality video or even HD video files… But the VersaPro VS-7 doesn’t care what format we feed it with Laptop battery. Once installed with the CCCP Codec, whatever file we gave the VersaPro played them… Even our 720p DivX video played JUST fine in full screen… Something that we never succeed on a Vaio P. Granted the Vaio P is powered by Vista, but once Vista installed on the VersaPro we did the same test with the same results. Flawless 720/30p DivX HD full screen playback!

Built for a more professional approach, the VersaPro VS-7 may often be used with office oriented tools, like Microsoft Office… And I even took the time to install PhotoShop CS3 with Bridge on this baby, just to be stunned to see that the little VersaPro VS-7 performed as well as my Vaio G2 with its 1.2GHz Core 2 Duo and 2GB of RAM… Yep, you are reading this right, the Nec VersaPro VS-7 Netbook, that costs twiceas less as a Vaio G2 is capable of handling photos under bridge and PhotoShop CS3 as well as the Sony PA3331U-1BRS Satellite A10 battery VGP-BPS3! Unbelievable!
Conclusion:
Ultra compact, ultra light and powerful, the VersaPro for the first time is a computer I love to carry around with me and does exactly what I need when I work on the go. Sure the VersaPro is bit expensive and only available in Japan, but the difference in price is REALLY worth your consideration if you’re looking for a business tool as Pavilion dv4000 battery inspiron 5150 battery Inspiron E1705 battery… As for basic Email and Web surfing I even think the Versa-Pro is an amazing Netbook, I’d recommend it to anyone whose thinking of investing in either an iPod Touch or iPhone since it will give you exactly what you need and fits in your pocket.

ShanzhaiPad joins tablet PC party

10.2inchtablet3

The humble tablet PC has been the subject of substantial debate in recent months, what with the heavily rumored Apple laptop battery tablet and the forthcoming CrunchPad from the crowd sorcerers at TechCrunch. Not ones to shirk a fight, the shanzhai boys are ready to throw their own tablet into the ring; let me introduce to what I call, the ShanzhaiPad.

Original names are not a Shanzhai forte, nevertheless I’m sticking with ShanzhaiPad as the official name for this one. Besides ShanzhaiPad has a slightly better ring to it than simply ‘Ultra Thin & Light 10.2″ Touch Screen Tablet PC’ and Laptop battery , which is what I believe it has been christened in China. Still, it does tell us a lot about the device. It’s really thin, has a touch screen 10.2 inches big powerful  Satellite A10 battery, and is called a tablet PC.

To divulge further; the ShanzhaiPad use an 1.6GHz Intel Atom N270 VGP-BPS3 battery and a 945GSE chipset as the brains behind the operation. Interestingly the 512MB of system memory works in tandem with DVMT or ‘Dynamic Video Memory Technology’ a technology developed by Intel that allows distribute the memory between OS and graphics array. It’s supposed to improve graphics performance, but if you believe that then you should take a closer look at the chipset and smell the roses.

The 945GSE is as old as the hills and is in no way a stellar graphics beasty. In fact the whole platform here is fairly low-end, the kind that you see in most netbooks. The trade-off of course is that the Atom platform uses less power which helps with thin devices and longer  battery life as  Thinkpad X41 battery Thinkpad T30 battery IBM 40Y9797 EVO N410C battery Pavilion dv4000 battery.

10.2inchtablet5
Software-wise it appears to be running Windows Tablet Edition, which is perhaps not so surprising seeing as there are relativity few alternatives when looking for touch screen functionality. Windows 7 might help solve that. Then again, if you listen to Microsoft, what won’t it solve? Weighing in at just over a kilo, the ShanzhaiPad includes headphone and microphone jacks, 3 USB holes, a VGA port, Ethernet port, and a card reader. Again, this all sounds very much like a netbook  inspiron 5150 battery Inspiron E1705 battery Travelmate 240 battery, no?

Western Opportunity Analysis:

So according to Michael Arrington the tablet form factor is the next big thing and the CrunchPad is the definitive tablet design. ‘Welcome to couch computing’ is a slogan they’ve used. HHmmm…I think I get it. I understand the concept that tablets are ergonomically sound, and that improved weight and thinness from new forms of touch screen manufacturing opens new doors. Still I’m not totally convinced. The tablet and Tecra M3 battery Thinkpad R50 batteryhas been touted as the next big thing since forever and the public just haven’t bitten yet.

The ShanzhaiPad might not look quite as glamorous as Arrington’s sleek concept art, but it is another way to repackage the cheap hardware have been powering netbooks for the last year or so. Arrington talked initially about a 200$ product for  Lenovo 40Y6799 Pavilion ZD7000 battery and this now seems to be a considerable over reach. I’m thinking it might be 0 with a ball and chain subscription, more like 350US or 400 without. The Shanzhaipad apparently costs the equivalenty of less than 250 dollars or 1700RMB, and why not? After all, it’s basically a netbook sans keyboard.

Asus Eee PC is becoming the history, Netbooks is stepping into declining years

Asus Eee PC is becoming the history, Netbooks is stepping into declining years

The article is first posted in http://www.laptops-battery.co.uk/blog/

Along with the Intel readjustment, after Netbook experienced a prosperous age, it become step into the old age. Asus and Acer are the first to announce stop developing & researching netbooks to follow the light & thin laptop battery comprehensively.?

Eee PC

According to relative media reported the two laptops manufacturers, Asus and Acer has already stop the develop working of this second half year but turn all the energy into the light & thin notebooks like Latitude D600 battery. This is mainly because Intel postponed the publication of next generation netbook flat roof Pine Trail-M and MID flat roof Pine Trail-D to the 1st quarter of 2010.

But there is some information disclosed that ASUS may promote Android flat roof netbook products the later of this year, but the publication date is after October. Besides, touch model flat netbook Eee PC T91/T101 products will be follow up after the official selling of Windows 7 with dell laptop battery.

Another side, for the light & thin laptops based on CULV flat roof, ASUS already prepared 12 inch, 13.3 inch, and 15 inch machine type, 13.3 inch is the mainstream products, and it will be increased 12 inch and 14 inch model in August as Ibook G4 battery.

For Acer, the netbook products are still promote 10 inch Acer Aspire One battery series as the main products. Regarding the light & thin laptops, Acer already own 13.3 inch, 14.1 inch, and 15.6 inch, three machine models, and plan to add the model with collocation of ROM and independent display card according to the needs of market.

The two leading manufactures stop developing netbook products to developing thin and small laptop (Powerbook G4 battery), it is not some goods news for netbook market and it will bring chain-reacting. Meanwhile, it also proved that netbook market has already passed and will be replaced by light & thin laptops.

New Lithium Battery Could Take Seconds to Charge

A new lithium Laptop battery technology might mean rapid charging and discharging times that take just seconds instead of the minutes or hours we’re used to.

Years ago, scientists thought that the reason why lithium-ion Discount laptop battery have slow charging and discharging times is because the ions travel across the battery slowly. But that wasn’t the case at all; in fact, various tests reveal that the ions are shuttled across the battery very quickly.

The real reason why charging and discharging times are slow, is that the ions can only travel through tunnels accessed from the surface. Only ions positioned immediately at the entrance of the tunnels can be shuttled across. The answer then to the slow charge/discharge cycle is to design a new surface more conducive to traveling.

I can image that in the future : we can charge my Thinkpad X31 battery, thinkpad x30 battery, Thinkpad t20 battery, Thinkpad T42 battery in 10 minuters. 

Ceder and Byoungwoo Kang from MIT addressed the need for the new surface by designing some sort of a beltway that takes the ions directly to tunnels for faster traveling. According to MIT, the new material tested could be charged AND discharged within just 10 to 20 seconds as opposed to the usual six minutes the current material of the same volume would take.

The new battery technology is an upgraded version of the current lithium iron phosphate battery as opposed to lithium cobalt because the former is not prone to overheating. Moreover, the new technology does not lose charging capacity as time goes by, allowing for the development of smaller and lighter products. Production of this new battery does not stray far from the current process, so Ceder believes it would take only two to three years to get the new technology in the market.
