yes its true .my hp nc6230 has this problem for over a year now since i installed the beta version.my battery was then 2 months old and when i plugged out my charger i instantly received a message saying your battery is low (at 99% ?????)and you should replace it soon .i can keep on working for an hour and a half after that .i thought it was the battery , till now .

After upgrading, Win 7 did not detect either of the 2 Dell issue batteries I have for a Latitude D820. I bought a replacement and it seems to be working ok.

I have a dell inspiron 1720 and after upgrading to windows 7 my battery lasts about 15 minutes. It constantly says there is a problem with my battery even though there never was a problem before I upgraded.

True indeed. My Lenovo R61's reportable battery life dropped down from 4 to 1.5 Hrs. This happened after I upgraded from Win7(7100) to (7600). Going back to factory set Vista and running a battery gauge reset and then reinstalling Win7(7600) too didn't help.

Apter upgrading to windows 7 my 6 cell battery that used to last about 2 hours when unplugged when i had vista, now lasts less than 10 minutes

yep. my sony vaio vgn-nr220e is not holding a charge at all. Sont says "we are not going to update drivers for 7". SONY?!?! Like they don't have the resources to update drivers for a 800 dollar laptop? Ridiculous.

After I upgraded my Toshiba Satellite P-305 from Vista to Windows 7, my battery life went down to about 25 minutes, and asked me to replace my battery. I bought a 9 cellreplacement battery but the message persists and the new battery will not hold a charge.

Got my Acer notebook 5 month ago and update it to windows 7 Home Premium from Windows Vista . Now with windows 7 , my notebook battery can only last about 40 min even with Acer Powersmart on instead of 3 hours in Windows Vista with Acer Powersmart on .

Hope got a solution for this soon .

My battery is dead and only after I installed Windows 7. Worked fine before that. In addition, my laptop is also running much hotter since the install. I tried for hours to figure out the battery problem and finally resolved to either buy a new one or just leave it plugged in. Then I heard this news...I really hope Microsoft helps us out!

I've got a pre-release candidate of windows 7 running.. and my battery life seems to have improved since i used vista.

Same issue here EEEPC1000h Windows7 get the message consider replacing your battery. Tried discharging all the way down from bios screen and recharging unit just with adapter plugged in maxes out to 22% when OS is running no joy at all. I think the battery is destined for the bin.

Raoul,

We are investigating the battery life issue in conjunction with our hardware partners, which appears to be related to system firmware. We are working with our partners to determine the root cause and will update the Windows TechNet forum (available here: http://bit.ly/cobVvf) with information and guidance as it becomes available.

I have windows vista the program very bad Because The device's battery does not last more than a quarter of an hour.

time of battery is low with win 7

Yes, but I guess nobody is perfect. Hope SP1 will fix it. Still, "XP is nobody" for me

2.5 year old LG R500, upgraded from Vista Business to Windows 7 Professional 2 weeks ago. 1 hour battery time on Vista B, after upgrade to W7 and using it for 1.5 weeks, the battery is totally dead (you can not charhe it at all).
PC runs OK with power-cord attached. I have called Microsoft Sweden, they claim it is not their fault, please contact LG support. Have done that, LG claim it is not their fault. Pointing fingers!

Dell Studio 1535 1 year old.After Windows 7 installed in my laptop a message "Plugged in but not charging" appears every time.My battery is dead.Worked fine before this upgrade,from Vista to Windows 7. I tried for hours to figure out the battery problem(BIOS and some tricks) but nothing works for me. I just leave it plugged in but compatibility is the most most important thing for any user.Support for this kind of problems cannot be guaranteed for any manufacture.

I purchased (9/09) a new Lenovo X200s laptop with Vista and after 5 months "upgraded" to Win7. My 9-cell battery that was providing over 9 hours of usable life on a full charge almost immediately declined to under 4 hours after the switch to Win7. Diagnosing cell failure under warranty, Lenovo has since issued me 2 new 9-cell replacement batteries, neither of which can charge beyond 4 hours. Although very accessible, Lenovo's techs are serving up a lot of lip service, which has precipitated a case escalation for me to a Lenovo executive (still waiting). Very frustating.

I have experienced a major drop in Battery life more than 50%, since reinstalling my PC to Windows 7 x64 Professionel on my Lenovo W500 (type: 4062-3JG).

Which makes it hard to work efficiently on my laptop, when not close to a power outlet. Very unsatisfying and frustrating!

HP Compaq 8710p upgraded to Windows 7. I used to get 2 to 3 hours of battery life; now I am lucky to get 30 minutes. Very frustrating indeed - no one seems to have any answers.

Interesting ... I upgraded from XP to Win 7 and at first did not notice any change in battery performance, BUT recently I did not use my fully charged computer (Toshiba NB200) for about a week and noticed that my battery life on resumption was about 20%. Tried this a few more times with the same result. I'm not technical but it sure seems that Win 7 is running something in the background after the OS is shut down (using the normal shut down process).

Would be interested in hearing any update on this.

Thanks

I have a Lenovo Thinkpad T61p that I upgraded to Windows 7 Enterprise 64 bit (4 GB mem, Core2 processor). No battery problems after several months of operation. My battery is just over 2 years old and does have a reduced life relative to a new battery, but I have not noted any undue power drains when running Windows 7. The biggest power drain appears to be keeping the LCD on bright, which was true previously with Vista/XP. Lowering that intensity certainly increases battery lifetime.
I have noted that the suspended system will occasionally move into hibernation mode even when the battery power seems fine (or is plugged in) even though I have set the power settings not to do this unless the battery drops too low. I have not yet figured out any pattern to this.
No other Windows 7 issues with my notebook at this time. Works great!
I even upgraded an older T42 Thinkpad for my sister from XP to Win 7 Enterprise 32 bit (2 GB memory) and it was quite peppy, which surprised me.

Same problem here guys. Installed Windows 7 Ultimate 64 on an HP DV9010US laptop. HP Battery Check shows I need to replace the battery and battery life is under 1 hour. Formatted the HDD and installed Vista Ultimate 32. No messages to replaced the same battery and battery life back up to 3.0 hours. Will test this week-end going back to the default Windows MCE and see what that does. BTW I ordered new batteries so I'll test them as well. C'mon Microsoft, we all need a Service Pack.

Likewise here - my wife and I have identical Toshiba Satellite laptops, bought on the same day. I upgraded to Windows 7 in October 2009, and by January the battery was lasting only about 30 minutes (and has more than 70% wear). My wife's laptop, still running Vista, still holds the roughly 1:45 - 2:00 hour charge, and has only 8% wear.

I installed windows 7 on my Toshiba A200 laptop. Prior to installation, battery life was bout 2hrs on 'power saver' but with windows 7 it began to show just above an hour but lasts below an hour. To compound it, bout 4 weeks back, it started giving me d message 'consider replacing battery'. Back to sub-optimal vista now and no more error msgs, battery better than with windows 7 but not as good as it was with prev vista.
Also, my friend installed W7, almost av d same time i did, now his battery which is younger than mine is completely dead.
Last week, a friend told me to help her install W7, just after i did, her battery meter read 2hrs 42mins on full battery (balance power usage). But now. It reads just bout 2hrs and actually lasts less.
Everybody must understand that we all do not want to complain against MS but there's somtin bout W7 that not just gives a battery msg but actually destroys it.I decided to write based on 3 of 4 systems i saw wit d problem, leavin d many complaints from many of my friends bout this same battery vampire W7. Microsoft really has 2 do somtin bout dis&stop denying d veracity.

I purchased an HP G70-460US last May. It came pre-installed with Vista (32-bit). The battery charged consistently to 98%-100% when plugged in and the battery life performed as expected. In November, I received HP's free upgrade from Vista to Windows 7. Ever since then, battery charge hovers around 20% to 50% but almost never goes above 95%. There's no consistency in when plugging in the laptop will or will not increase the battery charge. I've tried plugging it in while using it, after it's asleep, before it's asleep, after it's hibernating, before it's hibernating, before closing the lid, after closing the lid and on and on. I continue to read of those who have gone back to XP to see the battery chargin problem go away and then back to Vista to see it reappear.

Eighteen month old Toshiba Satellite L40, originally came with Windows Vista. I installed the RC1 Windows 7 and then the RTM version. Although I don't use it on battery very often (I use my Netbook if I'm taking my computer out!), the battery seems to be perfectly OK with a life of about 2 hours before needing re-charging.

I have an hp dv6000 with Windows 7 now running on it. And I can tell you, for a fact, that this is an actual problem.

In my particular case, my original battery had an estimated 79800 mWh available on it at full charge (just a little under the 88800 mWh it was originally manufactured with). After installing Windows 7, the wear level almost immediately dropped to 55%. That's insane on its on. But worse, everytime I used the system on battery the wear level drastically decreased until Windows 7 refused to run on battery at all.

So I replaced the battery with a brand new HP battery. Right off the factory floor so to speak.

After barely 2 months, my second 88800 mWh battery is down to 28890 mWh capacity. I'm a technician so of course I have tested my hardware such as the power regulation on the motherboard, made sure all my caps were still good, ect. The computer is just fine otherwise. There is no explanation for this. Especially since Vista never had a single problem with this on the same laptop.

So yes, Windows 7 may USE more power, but that does not explain the drastic drop in battery capacity very quickly. This is clearly an issue with how Windows itself is interfacing with the battery's memory to report proper values. It seems to me that it is somehow damaging or corrupting the values on the battery.

If Microsoft says this isn't a Windows issue, they shouldn't be building ANY software, let alone an operating system. Common freakin' sense here people!

I bought 2 acer timeline on august and register for the win7 upgrade, the battery usually last for 6-8 hours on vista.

After upgrading to windows 7, and use it for around 2 weeks, suddenly the battery drop.
one is dead, and the other one only last 15minutes. i suspect it's windows 7 cause.

sending both laptop for warranty claim.

I used to show ~3-4 hours of battery life in my Dell Laptop XPS 1330M with Vista.

After I upgraded to Windows 7, my battery life starts at ~ 1 hour ad 45 minutes!!!!

What's up?

Have recently upgraded entire school to Windows seven. Brand new HP 6730b laptop gives same battery error. This is the first time that it has ever been used.

I agree with every single person who has the same issue. I just got a laptop around two weeks ago with windows 7 already installed. I have been noticing that I need my laptop plugged in AROUND THE CLOCK to stay constistently connected. It takes a while to get to 100% and when it's finally there, the power diminishes to 50% in like 30 mins.!

I fear that in the next month a full charge will only get me like 20 mins of computer time. It's HORRIBLE that Microsoft has been keeping this a secret and hasn't dealt with it for nearly a year. Sooo many people are speaking out and are having problems with it, yet they continue to ignore every complaint.
A laptop is supposed to be for ease and convenience! This seriously feels like I'm on a DESKTOP. If they do not come out honestly and fix this problem, I will be changing my OS (maybe even a MAC if they continue to take no action)!!

This is very serious and really irritating!

i hate win 7 my battery is losing power after 25 min

Have same problems with HP 8710w , the battery last for 30-40 min, then it's shot down without warning some times, other times it's says it have 5% left and after 30 sek it shots down.

Since I installed Windows 7 PRO 64 bit, yes I have seen a most definit issue with battery life. And this on my HP 6730b 64 bit laptop, previously with Vista changed to XP PRO and now finally Win 7 pro, clean install. Well as clean as I could make it.

Thanks for this thread.

I have 2 notebook both of toshiba.
A 2005 model and and 2009 model.
I never have issue with battery on both notebook until i installed Win 7 on the new one.
I never have a month with Win 7 and my battery sucks.
Now i can't start my 2009 notebook unplugged, yet the older one on XP still enjoy the duration it has since the day i purchase it. What's wrong with this OS? Is this design for Desktop users only? So frustrating...

I have an HP Pavillion dv6850er... I've upgraded my laptop from Vista to Win se7en..... I still don't have any issues concidering the laptop's battery.... everything works fine for me... Otherwise I must agree while I'm using Win 7 the battery is running out too quickly... but I guess that's ok.... it's all cause of Aero style and other imrovements that Microsoft has made to improve their system, to make it better & much more stable...

A system is a system and we cannot blame it... I have Ubuntu 10.04 and Windows 7 in one laptop its called a Dual boot laptop. I currently have the problem and Windows 7 is not wrong. I go into my other Operating System Ubuntu and it says Battery may be old or broken and considering a replacement so i dont blame windows 7 i blame the battery structure Litium Ion... It may blow but we gotta deal with it... if you need tips on how to prolong battery life take this...

I don't know about you guys.... but here's my story. i have a HP Compaq Presario Cq-42 with windows 7 32 bit Home Premium and I purchased this laptop around in April 2010. Couple of days ago this "consider replacing battery " issue popped up but easily subsided. Now it happens all the time as long as i am plugged in to the charger. The weird thing is that when i plug out the charger it will flash the warning sign for awhile and after wards it works fine, no crosses, nothing. But the problem returns when i am charging my laptop. This shows there is nothing wrong with my battery but rather something with the software Microsoft has concocted. I have been searching all over the net for a solution and the only one i have is one that can only fix the issue by chance and it doesn't work always. To top it all off the issue has been buzzing all over the net for more than a year now and Microsoft has not even come up with a solution? No offense, but this is poor performance from the techies of Microsoft. This is very upsetting as i am only 18 and studying in college with little money to spare to repair and/or replace my laptop and all the info i have pooled all leads to a very high possibility of the battery permanently impaired or destroyed. and these batteries cost ALOT. anyone have a solution to this annoying problem?

I have a Pavillion DV 6000 which I updated from Vista to Windows 7 about a month ago, my battery life has gone from 2hours to 15mins in that space of time! if I had of known that I would of encountered this problem I would of just bought a new Laptop. Microsoft doesn't seem to be doing anything about the problem. Why wasn't this flagged before people go up grading! has anyone found any solution to the problem?

Less than one year old Sony Vaio. New install of Win 7 from XP 2 months ago, battery life fell from 2.5-3 hrs to less than one hour in the first week.

How I fixed my "consider replacing your battery
and batery life

Microsoft them lazy to fix the program / Win 7 ACPI /. Unable to Win Xp to work and the battery is charging, if Win 7 is not working and the battery is not charging! Complete crap!

same thing here as of today March 3, my HP DV6 model# 1134Ca has the same issue after upgrading from vista to win7 pro, battery only 6 month old and now last only for 11 min max then shut down, when start again the battery starting charging from 70% and up.

well guys, i have a sony vaio VGN-fw140e , originally came with vista, battery life was about 3 hours, when i switched to win 7, sudden drop on my battery life, and lasted only for 10 mins, so i tried to downscale my laptop, and reinstalled Vista, it is working fine ........ so that i overall concluded win7 had a problem....... now as like you all i am searching everywhere in the microsoft website and search engines to find a solution for this .....
(Not only a problem in Battery also the same result faced in DVD-RW)

I upgraded my laptop from vista to windows 7 after a couple of days the computer stated that i should consider replacing my battery with red x.

I tested installing windows 7 into three different laptop and all of them have a battery issue, 1)stucked at 0% battery plugged in but not charging, 2)stucked at 60% plugged in and charging(but on actual not charging) and 3) consider replacing your battery with X mark.

One laptop has an extra battery and charger both tested but the same fault, considering that there was no battery problem when using vista.

Is there any real solution for this windows 7 battery issue from microsoft or from anyone here?

thanks for the help.

Same problem. Dell Inspiron 1525, battery lasts half as long as it did under Vista. (And everyone told me Windows 7 was easier on the power than Vista. Maybe I should return to Vista....??!?!?!! )

Looking at this thread suggests Microsoft has just given up with this issue, leaving its customers dissatisfied again. And to think I PAID for this "upgrade"....

I upgraded from Windows XP to Windows 7 this year, along with a battery replacement for my Acer laptop. The laptop is about 6 years old, but the battery just recently stopped working and does not survive more than 5 minutes without being plugged in. Perhaps this really is a problem to do with Windows 7 that should be worked on.
