I'm getting insane (4+hours) battery life with my 6cell (I have SSD drive, t9500 processor, nvidia grpahics). Thinking of getting a 4-cell battery -- I've heard they save almost a pouind.
Anyone using a 4-cell? What kind of bettery life are you getting?
My xps 1330's battery just went completely dead (past the one year warranty period obviously) and considering how stupidly expensive the dell replacements are,
I was wondering if anyone had any experience with non-official replacements. Some places seem to sell a generic version of that battery for about half the price.
So the question I'm asking myself now is: 'what's the catch?'
Anyone running Win 7 RTM and noticing lower battery life? My 6 cell can barely push 2 hours, though its missing about 30% of its capacity due to wear. Its about 18 months old with a lot of charge and discharging. I do like Win 7, the laptop is running very snappy with it.

I copy paste from the dell.com.sg website: ...
I just got a new Macbook Pro and wanted to share my battery life experience with you:
- Safari open with 5-6 tabs, WiFi on, Bluetooth on, full brightness, just browsing random websites + youtube = 5h:18m
- iTunes playing in the background, Safari with same random websites open, about 60% brightness = 6h:09m
So far the display eats up a lot of battery life.
- Watching HD YouTube (I was watching the Home Project), 100% brightness: 4h:41m, 60% brightness: 5h:23m.
- SD video with Quicktime: 5h:10m with 100% brightness
- HD video with Quicktime: 4h:38m with 100% brightness
Playing the Sims3 with everything max details (1440x900 resolution on OS X) and 100% brightness: 2h:58m (wifi on bluetooth on)......
So the other day I decided to actually read through the crap that dell gives you (safety and precautions stuff) and in there it said with the new lithium ion batteries its actually better to not let them die and keep them above 40%.
In turn I decided the best way to do this is by charging them fully then just taking them out and letting my computer run off of the outlet.
Worked so far for me and this will prevent charging/discharging my batteries constantly. Anyone else done this? Any negatives to this (other than the obvious, which is if power is disconnected it will turn off). My computer is a studio XPS 1640 by the way.
Hey guys just got my xps 1645 and im having throttling issues but not so much when plugged in but when running on batteries. I play cod4 and when i start game when plugged in it seems to be a bit juddery at first kind of just stop and start gameplay but then seems to smooth out after a min or two. (I updated bios to ao7 and rang dell asked them for 130 psu and the tech told me there was no longer an issue with my model in my country (crap) i just hung up. but i will ring back when i have time and demand one (im within my rights ya??) Anyway when i plug out during game play the game lags badly going down to like 10 or 15 fps as opposed to 60 fps plugged in (aa off) anyone any ideas??
View 8 Replies View RelatedThe Acer Timeline 3810tz is advertised to get 8+ hours of battery life. Those who have tested get about that amount while browsing the web and doing simple task, and this model contains a single core processor. I read somewhere that the Acer 3810 model with a dual core processor SU4100 get half that battery life and only goes about 4 hours.

All tests from Dell webpage passed successfully. Tests from Intel Diagnostic tools passed. However, fun is always running, lap top is warm and battery goes down very quickly, in an hour. Under windows 7 it used to last much longer. I even did a clean install of Windows 8 and the problem persists

When the AC adapter is unplugged and I'm running on battery power the whole system lags. It also turns of when unplugged without warning after about 15 minutes.
Also, I get these error messages in my event viewer a couple of times an hour:
Log Name: System

Event ID: 13
: The embedded controller (EC) did not respond within the specified timeout period. This may indicate that there is an error in the EC hardware or firmware or that the BIOS is accessing the EC incorrectly. You should check with your computer manufacturer for an upgraded BIOS. In some situations, this error may cause the computer to function incorrectly.
When I run my uMB on battery, I can't seem to run an external monitor on it. Is this normal?

I bought the Acer 1410 with the single core SU3500 Core 2 Solo CPU. It looks like Acer decided to release them with the SU2300 now, which is dual core at 1.2GHz (compared with 1.4GHz of SU3500).
Does anyone have any benchmarks comparing the two, and/or if they have a solid understanding how much better it would perform compared with the SU3500? I also see that the single core AS1410 with Celeron M @ 1.3GHz sells at the same price as the dual core.

upgrading my Aspire 5570 notebook more than a year ago. This time, I’m feeling lucky to share some of my experiences about how I finally upgraded my CPU from a Core Solo T1350Core 2 Duo T7200.
Again, thanks to everybody here in Notebookreview forum especially adinu, hoggie, Mack1982, TehSuigi, krazyphire and bigozone for their insights and knowledge that helps me a lot throughout the whole process. So, let’s get started!
Pre-upgrading
Please refer to these post before you start. It'll save you a lot of time and trouble later on.
Upgraded Acer 3680 Celeron CPU to a T5300!
Aspire 5315 CPU Step-by-Step Upgrade Guide
What you’ll need :Your new CPU (make sure it's compatible with your system ie; socket, FSB)Latest BIOS from Acer (upgraded to 1.3505 or latest)A good thermal paste (I would recommend Tuniq TX-2 or Arctic Silver 5 as well)Basic tools (screwdrivers, forceps, kitchen paper)Body static discharger (I would definitely recommend this as a precaution)Some alcohol, ear buds, sand paper grid 600,1200 & 2000 (optional for heat sink lapping)Lastly TIME and PATIENCE (you’ll be needing these a lot definitely!)When you’re ready, lets get our hands dirty.
How to disassemble your notebook?
I found out a very good video tutorial on how to disassemble my Aspire notebook on YouTube. So please take your time to view it and follow step by step as shown to help you to go through the process.
Lapping your heat sink (optional)
Although it’s not necessary, but I would recommend this process as another way to improve heat dissipation on your newly installed CPU. Refer to this page for detailed instructions.
The simple process:Clean your heat sink from old thermal paste residues with alcohol or equivalent of it using ear buds and kitchen papers.Apply a 600-grid sandpaper to smoothen the heat sink surface which comes into contact with your CPU.Repeat the process again with a 1200-gid sand paper until you’re satisfied.Finally, finish up by applying a 2000-grid sand paper to give you an almost mirror-finished surface. Wipe clean any dirt and residues left.....................................
I will be buying a new laptop to replace my Acer Aspire 5738G.
I am considering HP Dv8t Quad Core i7 or HP Probook 4720s.
I am a web developer and I some time use my laptop continuously for 2-3 days.
choosing between these 2 laptops, which one will be better for me?
I recently purchased a new HP laptop and have a few questions.
The computer came with a lightscribe drive and is removable since it also came with a empty filler for the optical drive. Is it ok to remove the drive and/or plug it in while the computer is on ? Same thing w/ the battery... is it ok to pop the battery out when the computer is on AC power, or put the battery back in when the computer is plugged in ?
I recently got the Macbook for Christmas and it has been giving me no problems until last night. I was watching a video on it and I had it plugged in, as the battery was running low, when it all of the sudden went blank and shut itself off. I thought that maybe the battery had died for some strange reason, since it had not been in its charger long, went on my other computer and dismissed the situation until this morning.
When I unplugged it, checked the battery life (it was full, by the way, 8 green lights came on) and then tried to turn it on, nothing happened. I held down the button for a long time and still, nothing. I tried plugging it back in and turning it on, still nothing.
I got the manuel out and tried the Command, P, R and Power button thing, which made the laptop make a small noise. Then I tried once again to turn it on, but the screen just went to a lighter gray and nothing happened. When I pushed it again, it went dark. I tried removing the battery and putting it back in, but it still did the same, and I even tried holding down the power button for five seconds while the battery was out. Still nothing.
I want to upgrade my old laptop to something nice, and am torn between to systems.
An HDX 16 with:
2.40 Ghz dual core duo ( P8600 chip )
6 gigs of ram
OR...
An HXD 18 with
2.0 Ghz QUAD core ( QX9000 chip )
4 gigs of ram
both systems have the same video card ( Nvidia with 512megs of ram ) 500 gig hard drive.
What would be the faster machine for doing video ? and what would be the overall faster machine ?
I realize that not all applications will take advantage of a quad-core chip like the QX900, so this is why I"m asking. if the dual-core P8600 chip @ 2.40 Ghz in the HP HDX 16 with that 6 gigs of ram will actually be faster overall than the quad core would be, and perhaps even be faster at rendering video ?
On my Black Macbook is it when it is charging the screen feels different than when it is running on the battery. For example, when it is charging and I run my finger along the screen there is more resistance and it is not as smooth as when it is running on the battery. Is this normal?

Aside from the fact thats free and all, my real concern if it will yield better gaming performance and battery life.
Was toying with the idea of getting a 15" MacBook Pro, but as OneNote is a major application with me, dual-booting with Windows 7 like I'm running now, or using Parallels, is required.
What kind of battery life are you guys getting with Parallels / Fusion (or running Windows natively via Boot Camp)?
I have an Inspiron 7010 which is 2 years old. In control panel devices it tells me to troubleshoot the laptop and cannot rectify problem with Broadcom virtual wireless adaptor. Secondly running the diagnostics say the Read test is not running. These are the only problems but are not affecting the efficiency of the PC. Should I ignore it?

what the performance difference is between the Intel Core i7-620M and the . Intel Core i7-820QM. I always thought the quad core 820QM was faster, but on the hp website the dual core 620M is more expensive.
Is the 620M faster? And is it faster for specific things only?
