Acer :: 6920 Battery Life Under Windows 7

Dec 2, 2009

After upgrading to Windows 7 Professional the battery life on my 6920 has taken a dive.

I've always thought that the meter was just messed (never used it long enough on battery to test), but today my battery completely drained in a little over 30 minutes.

Under Vista, I was getting around 2.5-3 hours of usage....

Sony :: Vaio TZ SSD+HD Battery Life- Also, Windows 7

Mar 7, 2009

I just ordered a Vaio TZ2500 Premium with the dual drives. It's intended to replace a MacBook Air. While I like the Air a lot, I just can't get used to its big footprint and short battery life. My school's library is pretty old and wasn't really built to accommodate lots of laptops, and often it gets really difficult to find an outlet. I was wondering, what kind of battery life should I expect from the TZ SSD+HD with standard battery?

My usage is very light. Most of the time I'm just looking at PDF's, maybe running some light stuff in Matlab, and Office and Excel 2003.

My other question is, has anyone tried Windows 7, and if so, do all the drivers work correctly?

Sony :: Upgraded Vgn-sz110 To Windows 7 = Get 20-30 Min Of Battery Life

Dec 6, 2009

I have a 4 year old vaio vgn-sz110b with windows xp home.

My battery wear indicator according to mobilemeter is 11% wear.

With windows xp I get 2:30 -3 hours of battery life.

I decided to bite the bullet and finnaly get windows 7 pro.

I created a seperate partition for windows 7 so I can dual boot windows xp/7.

After installing a fresh copy of windows 7 and most of the essential sony programs I decided to test out the battery performance and silly me, I really thought windows 7 would improve the battery performance but the results were absolutely disgusting.

With my fully charged laptop, I unplugged it and watched a movie to see how fast the battery would drain. Normally on my XP OS I would get 2:30 hours of watchtime. When the movie started I looked at the clock and it said 1:20 pm and I took a mental note of that. Shortly after the film the battery baloon popped up saying that the battery had reached critical level. I looked at the time and it said 1:40, I laughed thinking it ws just a mistake. Then in less than 3 minutes my laptop went into sleep mode!.............

Sony :: VGN-SR190 Battery Life Shorter Under Windows 7

Nov 11, 2009

I used to get 4-5 hours under Windows Vista. Now using Windows 7 Ultimate Edition and I'm lucky if I get 2-3 hours. The Sony site has no Windows 7 drivers for the SR190.

Apple :: Macbook Pro 17 Windows (vista/7) Battery Life

Nov 19, 2009

what the battery life of the new(er) unibody macbook pro 17 was like under windows. I read a review somewhere that says the new macbook pro (the one with advertised 8hours battery life) managed about 1 1/2 hours in windows, is this true? the only reason I'm looking at the 17inch pro is because I program a lot in Windows and Linux, and 17inchs would be fantastic to display more code, but I still need good battery life. portability is no issue, as I'm a big guy and I carry 2 computers with me right now anyway. any other cons to installing windows on this beast?

Dell :: Vostro 1400 9 Cell Windows 7 X 64 Battery Life

Nov 18, 2009

I'm super happy with win 7 x64 on the vostro 1400, except for the terrible battery life. Off power, it's less than 40 mintues even on the 'power saver' mode. I'd get 3 hours plus out of my 9 cell battery on XP...

any suggestion as to how I go about improving this problem? anybody else experiencing this?

I've looked for some answer here, but not found too much except for how to get RM clock to work on x64 so far.

Acer :: Installing Windows Xp Pro- Aspire 6920

Sep 16, 2008

I have aspire 6920 and I love the features this computer has but I am not very happy with vista. Can I install xp pro? I know that deleting the pq service partition is not wise but I would rather have xp pro. How do I delete pq service? Also, is this action reversible? If I can install xp can I ever go back to the manufacturer OS? I have created the restore cd's but will they work without the pq service partition.

Acer :: Battery Life On Aspire One

Jan 3, 2009

I just got the 3G version of the Netbook with the 3 cell battery. I'm only getting a bit over 2 hour of battery life with 3G off, my wireless connection on, the screen brightness about half way, and the only program open is Firefox. For example, right now I have 90% capacity and it's showing 1:55. Is this the normal battery life. I know the specs say up to 3 hours, but I never believe in those, and I just want to make sure mine is about right.

I was thinking of getting the 6 cell battery, but I don't want to make the netbook any bulkier than it is (I'll be carrying it back and forth in my work commute).

Acer :: 3680 Battery Life

Dec 21, 2008

Ive had my Acer 3680 since 4/07. I bought it brand new.

I keep it on the charger 85% of the time, and when its not on a/c power, I switch over to "power save" mode.

I was surprised about a month or two ago when my battery icon had a red "X" through it.

It would be there whether it was charging or on battery power. When I switched to battery power, it would be at 100%, but then be down to 7% in like 2 minutes and shut off. I was able to get a new battery on ebay and now I have no problems. I cant help but wonder though, how long are people reporting with their 3680's?

We have a Dell laptop at work that we've had for 5 years with the original battery. Im not trying to diss Acer or anything. It could be I just got a fluke battery. I'd like to see how long your 3680 battery lasted before you had to replace it?

Acer :: Upgraded To Windows 7 Sound Not Working (6920)

May 10, 2010

Just updated to Windows 7 Ultimate 32 bit. Everything seems to be working fantastic! But it seems the audio driver isn't right, as the sub isn't working and there's no mention of it in the Sound settings. The driver Acer supplies on their website for the Acer Aspire 6920 with Windows Vista Premium x32 also lacks this.

Where can I download the appropriate driver?

Acer :: Extensa 4620 Battery Life

Jul 3, 2009

My mom has an Extensa 4620 which couldn't have been already years old, but seems like its battery is giving way.. She told me she keeps noticing that instead of almost 2 hours battery life, now she only gets 30 minutes from it, in High Performance. I've installed RMClock on it not too long ago, but I'm sure it isn't because of that..batteries don't fade that fast, now do they? Can we like send it back to Acer or something since it already underperforms for its age?

Apple :: Summer 2009 MacBooks Running Vista / Windows 7 (or Parallels) - Battery Life

Aug 14, 2009

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)?

Acer :: SU4100 Vs SU7300 Battery Life Difference?

Jan 10, 2010

I"m looking at the comparisons between the Acer 1810 T and TZ models. The primary differences are in processor and cache sizes. Could anybody guesstimate whether there would be differences in battery life on the two models, ie the SU4100 and the SU7300?

Battery life is probably more important to me than slight performance differences.

Apple :: Heat - Design - Unibody White Vs- Aluminum - Battery Life Vs- Video Card - Windows

Apr 14, 2010

1.I really didn't find much info on the (now not so) new white unibody Macbooks, expect some items for sale. And please, don't tell me that just buy the aluminum model for the extra $200, my question is strictly from an engineering point of view: heat. We all know aluminum Macbooks are quite hot, right? But how does the white unibody compares to the aluminum regarding heat issues?

2.What might be the reason that the whole bottom of the white unibody contcts the table beneath it, compared to the aluminum model, which has four rubber contact points on the four corners?

3.On the other thread I read a dedicated graphics card does not really add to battery consumption. Can you confirm that?

My main usage profile is office, web and seeing (HD, if available) Youtube videos. This one is rather a 15" vs. 13" Pro question, and half hypothetic. Let's say, all things are being equal on two models, the processor none the least, the only differences are one model has the integrated Nvidia, the other the integrated Intel plus discreet Nvidia combo, which one would serve me better, regarding performance and battery life? The discreet graphics would at least turn on when playing the HD videos?

4.Running native Windows (7 or XP) still suck on Macbooks, because of the drivers?

Acer :: 3810 With Dual-core Proc. Reduced Battery Life

Nov 22, 2009

The 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.

Apple :: New To OS X - Battery Life

Jun 6, 2009

I'm new to OS X, got my MacBook the other day, and I can hands down say it's my favorite OS I've dealt with. It's so much simpler and just plain awesome. Okay, I'll ask my question before I get carried away...

So, I did some searching on Google after I noticed that my battery likes to hang around 99%. Apparently this is common. My question is, is this a BAD thing? When I see 99% I'm picturing that the computer is constantly pushing power into the battery so it can reach 100%. I mean, isn't that how fires start?

Simply put, is my MacBook trying to charge the battery consistently when it is not at 100%?

Apple :: Anybody Else Being OCD About Their Battery Life

Sep 24, 2009

every time I'm running my uMBP from battery, I'm constantly checking the amount of time I have left and trying to figure ways to increase that time. Yes, CONSTANTLY. Whenever I can, I'm using the a/c adapter.

Even though I may see 6-7 hours left, I'm still not satisfied.

And just about every time I am running the battery, I'll open up Coconut Battery to make sure I still have a 100% charge hold left....even though my umbp is 7 weeks old with only 4 cycles...

Dell :: XPS Keyboard And Battery Life

May 23, 2009

I have Dell XPS 1530 and I have 2 problems,

1 Keyboard. When I type cursor seems to jump around a lot. I would be typing and suddenly the cursor is in the middle of the previous sentence and its a mess. Is that something common, is that me or is that something I need to call Dell?

2 Battery life is extremely short. I hear of such thing as deactivating your video card ( I have GeForce 8600 GT) and that supposedly helps you with the battery life. Does this laptop offer such opportunity?

Dell :: Studio XPS 13 Battery Life

Apr 16, 2009

Why is the Studio XPS 13 so terrible on battery life? ~2.5 hours on power saving mode, 1 on high-performance. I believe the Sony Z rates around 3-5 hours on power saving, as does the Latitude 6400. Is it normal to have this low of a battery life for a 13.3"?

What is draining all the power? How does the Z pull 4-5 hours on its battery life?

I don't want to shell out for a 9-cell and also have to deal with the added weight... but this is ridiculous.

Also, are there any new deals for the 9-cell batteries?

Dell :: Optimizing I7 Battery Life

Nov 30, 2009

Here a bit of summary of how to enable some advance power plan settings, the highlights are disabling the core parking override and max % of unparked cores.

-Windows by defaults keeps at least one logical core active per physical processor core. With the nehalem architecture parked cores consume almost no power.
-Also keep in mind if you set max unparked cores to 50% it may still activate all cores because 50% of 8 hyperthreaded cores is 4.
-You can use resource monitor to see if cores are parking
-once you've done the registry tweaks below you should have some extra options in your advanced power plan settings
-Setting you power plan back to defaults nulls you the changes to it is harmless and reversable if you are careful
-If you are not comfortable making registry changes don't do this as you can really screw your computer up, if you mess up the wrong things in your registry

Open Regedit (type regedit into the startmenu search box)

Expand location to:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPowerPowerSettings54533251-82be-4824-96c1-47b60b740d00

In order to enable some advanced power plan settings you will have to rename the REG_DWORD "Attributes" to "_Attributes". This one it own does not change how your computer runs, it simply adds an extra option into your advanced settings for each power plan

Here are the relevant registry keys:
0cc5b647-c1df-4637-891a-dec35c318583
lets you set the minimum number of unparked cores (I set this to 25% for power saver)

3b04d4fd-1cc7-4f23-ab1c-d1337819c4bb
turns on additional processor throttle states, caution this throttled my laptop to the point that it was almost unusable you can change the attribute to _attribute but leave the power plan setting disabled.

447235c7-6a8d-4cc0-8e24-9eaf70b96e2b
Sets the processor power state when parked, I think the default is ok

5d76a2ca-e8c0-402f-a133-2158492d58ad
Option to Disable processor idle states, not really relevant on a laptop

a55612aa-f624-42c6-a443-7397d064c04f
Processor core parking override, this one is key, it you don't disable this in your power plan settings you will only park "virtual" cores

ea062031-0e34-4ff1-9b6d-eb1059334028
Maximum number of unparked cores, this is useful to put your computer into "dual core mode" in power saver if you set this to 25% or 50%
