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).

Jun 16, 2009

I am in the middle of choosing a new laptop (Acer Aspire Timeline 3810T with Core 2 Duo SU9400 versus this Acer Aspire 3935 with Core 2 Duo T7350).

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 :: 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....

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?

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.

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

The Acer Timeline 3810tz is advertised to get 8+ hours of battery life.

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%

Dell :: Battery Charger Life

Is it safe to assume that it is dead?

Are there any tests I can do to verify if that's the case?

I've had it for a year and 3 months, is that the typical life of a battery charger?

Dell :: Save Battery Life

Dec 31, 2008

i like having my m1530 on my lap (unplugged) in the living room while i watch tv/babysit so far i can only make it last 2 hours at the most(surfing the web,messengers) with the brightness 30% and powersaver mode.

well i was reading on the thread on how to underclock your cpu...theres a problem with that:

-numero first im too lazy (hurts my head when i try to understand the thread,hence the "[ADVANCE]" on the title ^^")

-numero dos having a t5450 on power saver mode (50% max perfomance) is slow enough... so i tried to look for a better solution and found this...

i think its great...my battery up to 2 hours and 20-ish minutes.

i think vista users should give it a try

Dell :: 1530 Battery Life

Oct 8, 2008

Ive always gotten, well, not so much battery life out of my machine. However, today Ive realized it might be a problem with it, rather than how it is meant to work. Today I put a DVD (AC/DC live!), plugged an hdmi cable into my tv, and it died half way the 2 hour concert. All my laptop was doing was working as a dvd, so, I figure something must be wrong.

Dell :: Vostro V13 / Battery Life

Mar 4, 2010

I'm looking for a new laptop for school/work, and so far I think the Vostro V13 seems good. What do you think?

[url]

Anyway, my only concern is that it only has four hours of battery life. However, it does come with a 7200 RPM hard drive, which seems like that would eat a lot of battery life compared to a 5400 RPM hard drive or an SSD. Well, I have an extra 80 GB SSD in my old laptop, so my questions are...

How much (if any) battery life do you think I would gain by replacing the 7200 RPM hard drive with the SSD?

Also... Would you recommend the Vostro V13, or is there another laptop that you would recommend for school?

My XPS M1530 is a beast, but it's starting to get worn out and it just isn't convenient enough to bring to classes all day. Netbooks are too small for my hands (and eyes!). I really do prefer big screens, but I suppose I must compromise for the sake of mobility/convenience, so hopefully I'll be able to get used to the 13.3" screen.

Sony :: Vaio Z Battery Life In XP

Dec 28, 2009

First time poster, long time viewer.

I was just wondering if anyone experienced a battery increase after down-grading their Vaio Z from Vista/Win7 to XP? If so, by how much?

I'm currently holding a Z710dd (canadian vaio) with a standard battery with windows 7 installed. I previously had a netbook that lost a good hour and half from Windows XP to Windows 7. Even after disabling a lot of the windows aero mumbo-jumbo and themes

Sony :: Vaio Battery Life

Apr 19, 2009

I recently purchased a Vaio VGN-SR390 with the "9 hour" battery. I understand you never get that. But what I think is odd, is that no matter what settings I change, including WiFi on/off, it *always* says 3:55 to 4:00remaining with 100% charge. (I haven't actually timed it on the clock, though.)

Questions:

1) Is this what other SR owners are getting? about 4 hours...no matter what

2) How do I make sure bluetooth is off (haven't been able to figure that one out)

3) Should I see the battery life increase with reduced display brightness, Wifi off, etc?

HP/Compaq :: DV2 Undervolting: Get At Least 25% More Battery Life

May 6, 2009

Following the excellent flipfire's undervolting guide and inspired by Silvr6's experience with undervolting his dv2, I decided to give it a try and...I was able to increase the battery lifetime from almost shameful 2h 25 minutes to 3h 30 minutes for mpeg 2 play, or even to 4h 20 minutes (light browsing and lots of reading). So, you get at least 25-30% more battery lifetime. This makes me like my dv2 a lot more!

Perhaps, it's the noted AMD's tendency to overvolt their CPUs, perhaps something else, but I was able to get the following 100% stable (in my case) voltages:

4.0x-0.6875 V
4.5x-0.7125 V
5.0x-0.7250 V
5.5x-0.7500 V
6.0x-0.7750 V
6.5x-0.8000 V
7.0x-0.8000 V (yes, its 0.8V again)
7.5x-0.8250 V
8.0x-8.5000 V

these voltages are stable for my particular CPU; yours might be slightly lower or higher. For example, Slvr6 was able to get a bit lower with 4x 0.675 V. Read the undervolting guide!

But I hope that the table above will encourage you to try the undervolting (btw, unlike the overclocking its 100% safe), since the benefits for dv2 and AMDs neo are so dramatic!...........
