Windows 7 "Consider replacing your battery" error [updated]

Windows 7 users are up in arms over a long-standing battery charge problem. Their batteries are dying prematurely, and they're blaming Windows 7, which is popping up the message, "Consider replacing your battery. There is a problem with your battery, so your computer might shut down suddenly." In IT Blogwatch, bloggers consider replacing their operating systems.

UPDATE Feb 9: Users scoff at Windows 7 battery problem denials

Your humble blogwatcher selected these bloggy morsels for your enjoyment. Not to mention iPad reality distortion...

    Ina Fried looks into it:

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. ... 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.


Microsoft suggests users contact their computer maker to see whether the warning is warranted or not ... [and] 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."

Lin Edwards sees the irony:

One of the Windows Vista problems that Windows 7 was supposed to solve was the drain on laptop battery life. ... Some Windows 7 users claim their laptop batteries have been permanently damaged by drainage problems occurring after they installed the new operating system.


Battery problems were noted by some users during the Windows 7 beta testing period, especially by those using Netbooks, but the complaints began to pour in after the official release of Windows 7 for general consumers in October last year.

Emil Protalinski adds:

Microsoft's stance is that the root cause of the issue is related to specific system firmware, meaning it only affects machines with certain BIOS releases. ... However, customers disagree with Microsoft's explanation since the problem appears to affect notebooks from more than just one OEM, and some claim their vendors have informed them that it's a Microsoft problem. The phrase "class action lawsuit" is mentioned.


Microsoft has sold more than 60 million copies of Windows 7, and it's not clear what fraction of those owners are having problems with battery life.

But fat_ray is at the end of his tether:

Samsung Q70 Aura Tirana Laptop. Worked fine under Vista (Batterywise). After I installed Win7 the Battery gradually but quickly lost its capacity.

When I bought the Thing in mid 2008 they advertised a battery Capacity of up to 6 hours.


When Win7 had brought my battery down to 25 Minutes worth of power I decided to [downgrade to Vista]. ... Now my laptop is back running under vista and as it seems, my Battery has taken a big beating in approx. two months under Win7.


I wont get more than one hour to work without having to charge.

On top of that. The Battery won´t fully recharge. It stops at 97%. ... My company is not going to upgrade until this is resolved..

And DanLee81 can barely contain his anger:

This is not normal battery behaviour. Yes, the values can return to normal on the battery information, but the battery still will not hold a proper charge. I've seen batteries that are broken from windows 7 that observe this behaviour, but while discharging, it will shut off like you took the battery out, but when you turn it back on, it will still run for another 30-40 min.


Windows will report that there is still X amount of battery left (eg: 50-60%) but the laptop still shuts off prematurely. Who wants a battery that does that? This behaviour happens in ALL OSes after Windows 7 damages the battery, not just within Windows 7.

Meanwhile, Varun Gupta twists the knife:

The same thing has happenend to my Dell XPS M1530. And i have been following up with DELL like crazy thinking this was an issue with the laptop. ... My laptop battery is completly dead and now i need to shell out 1/5th amount of the laptop price to purchase a new battery which will not charge up at all.


It calls for a lawsuit against microsoft and we should be getting replacement batteries from microsoft for this blunder.
