Windows 7: Microsoft investigating battery problems

Microsoft investigating battery problems

Apparently Microsoft is investigating battery issues with Windows 7.

Cnet news is reporting that Microsoft is investigating an issue that arises where the OS will display a warning message to replace the battery, reporting it as faulty.


Microsoft says it is looking into a problem that is causing some Windows 7 users to get a warning that there is a problem with their battery when, in fact, there is not.
"We are investigating this issue in conjunction with our hardware partners, which appears to be related to system firmware," a Microsoft representative said in a statement on Tuesday.
The warning in question uses the computer's basic input output system (BIOS) to try to determine whether a battery needs replacement. For some reason, the signals are getting crossed and some users are getting the message even when they should not.



However, because this warning is new to Windows 7, users moving from Vista should not necessarily ignore the message if they see it. Instead, Microsoft suggests users contact their computer maker to see whether the warning is warranted or not.
Meanwhile, Microsoft says it and the PC makers are trying to figure out what is behind the glitch. "We are working with our partners to determine the root cause and will update the forum with information and guidance as it becomes available."




Has anyone seen this warning after upgrading to Windows 7?

There is more on this topic in the Hardware section:
"Consider Replacing Your Battery"

This isn't just about a warning. It's about Windows 7 ruining the batteries of a lot of laptops. See additional links in the thread linked above to the hardware area. This issue has been given a lot of attention over the last few days because enough people have had their batteries permanently toasted that Microsoft issued a statement that they're "looking into it". It doesn't appear to affect all laptops, but enough of them that those of us with laptops need to beware. I wiped Win 7 off my new laptop and I'm using Linux on it now until this issue is resolved -- because Microsoft sure isn't gonna buy me new battery (unless the class-action lawsuit actually happens).

Well one thing I noticed with my Lenovo T61p laptop was that Windows 7 had no provision for adjusting the battery charge parameters and that Lenovo firmware that was rather poorly integrated with Windows 7 was required to have any control over that.

Well, on an aspire 4810Tzg (5800mAh) it is supposed to be 8 hours runs on battery, and it's quite true 'cause in the Manual Battery Instruction they do told to discharge 3 times then load it again...Can you realize about a 24 hours running on battery, then around 2-1/2 hours to reload it each time!!

Acer did provide a useful power management system config, to switch the graphic card from 512mb to 256mb video memory and a beside power management ( Intel(R) GMA Driver for Mobile ) working close together with Windows7 and the processor.

I didn't notice at all Windows7 taking a lot of resources and even pop up a window telling the battery went discharge faster than usual...
Crossing fingers by now! And hope it helps some Acer small-notebooks users!

edit:
Before was using an HP DV5000 series and early 2009 decided to test the RC 7100 and i was already owned the HP laptop since three years. The batterry was just a little normal weaked, but with multi-boot XP sp3/ Windows 7, the Os Windows 7 have never interact with batterry issue...My Hp laptop leaved me just with a "reallocated sector count" Hdd problem!!

Guess some will have hairs falling their heads reading threads at this rumor (fake or not).

Still crossing fingers anyway!

Hmm...maybe this 'problem' killed my battery
But I'm not making conclusions, I just think it is weird my battery died after switching to Windows 7. My notebook is a Compal JHL90, if anyone cares.

Hopefully Microsoft will fix this issue.

I have a newly bought Gateway P-7908u. Designed capacity is 86580mWh. First week run capacity was 88050mWh. 1 week later, with Windows 7 installed, it went down to 85037mWh. I also thought this is just wierd and I'm blaming the battery.

Currently (which is another 2 weeks later), it seems to stop charging at 82640mWh; says 97%, not charging. I'm not sure if it's supposed to be that since it used to always charge until 100%

Now that I've seen this article, I'm having some doubts. Not really making any conclusions though, too, even the slightest ones... :|

Not according to a lot of people on Microsoft Technet who've been looking into this issue for over 7 months. Do some real research before making a statement like that. And why would Microsoft feel the need to issue a statement about it if it had no basis in fact? And why is a class-action lawsuit being talked about? And why have most of the major computer reporting sites picked up on this? I'm talking about reputable sites that don't put up info unless it's been verified.

If you don't think that software can disable or damage hardware, well, you're not very computer-literate (ever heard of BIOS flashing?).

I actually like Windows 7 a lot and use it on my desktop... but until I hear more about the battery issue I won't use it on my laptop. Laptop batteries are expensive and there are too many reports of Windows 7 corrupting the EEPROMS in these batteries in a way that reduces their capacity to a tiny fraction of what it should be.

You didn't even read the statement about the problem did you?

Technet and News sites are not good places for conducting 'research' for facts about a problem unless you want information from people who don't have any technical expertise

The only offical statement from anywhere is from Microsoft and they said quote: "Windows 7 users to get a warning that there is a problem with their battery when, in fact, there is not"

People are obviously worried about their batteries and its clear Microsoft wasn't very happy with the amount of FUD being spread via the news and other sites and decided a statement was necessary to clear up the confusion.

LOL, A failed BIOS flash doesn't ever permanently damage/disable the BIOS or hardware itself, It just prevents your motherboard from booting up and thus working again. Most BIOS's are removable for this reason, so the manufacturer or yourself can remove it and re-flash it using a special kit.

Maybe you should read Microsoft's statement again
