Windows 7: "Consider Replacing Your Battery"

Here's another testimony (still on bit-tech.net) :

" Sounds like BS from MS to me...

First, to the people who say unplug your battery, that really isn't necessary. Most chargers, and in fact *all* chargers in computers, will simply switch off the charging circuit and run off mains power once the battery is full. Removing the battery is unnecessary and an idea based on pure paranoia.

@shanky - recharging lithium-ion batteries often doesn't really cause any problems. In fact, it's better to charge them often than to completely discharge and completely charge them; lithium-ion doesn't suffer from memory like other types of battery. For more info on this see How to charge - when to charge table

The problems people are having relate to capacitance - it's a case of the battery not being charged correctly. From the sounds of things, MS decided to use a new method for measuring batteries which not all manufacturers conformed to, but whether or not this is down to the manufacturers not conforming to standard design specifications or MS using a field that wasn't widely accepted I don't know. The reason it hasn't affected new laptops is likely down to MS telling manufacturers how their system would work, and them making sure the battery would conform to their specification.

@LucusLoC - As I understand it, the peope who have had this problem were running other versions of Windows, upgraded to Win7 and then after that their battery was ruined. Changing back to another OS, be it Windows or Linux or whatever, didn't do anything to fix the problem. Also, I think it's better to leave a Li-ion battery partially charged for storage rather than fully charged, but I could be wrong.

Thinking about it, for my girlfriend's Eee PC there was a BIOS update for Windows 7. It's possible that this updated the ACPI information about the battery, so that Windows 7 could correctly charge it. If that's the case, then so long as the laptop manufacturers have provided a BIOS update within a reasonable timeframe of Win7's release the blame might lie with the end user. MS could argue it's their responsibility to ensure any software installed is compatible and won't break the computer.

Still, I don't like the way MS have come out with this press release. It's obvious if you listen to peoples' complaints that there *is* a problem and it's not just down to battery degredation with age. At the end of the day, whether or not the fault really lies on MS' shoulders they're not going to admit it. The ramifications if they did would be immense, and they would likely have to compensate everyone who had their battery ruined.

I came to this thread to post a "potential" problem... and rather than getting proper responses, I got another one of those "it's your hardware" replies. Ok then. Gotit. Thanks.. Peace.

The actual batter BULGES physically, there are even pictures showing the problem... And you say no piece of software can affect hardware? Please....
So you want me to be extremely technical? Very way. Operating Systems and software that run on top of the hardware and its firmware cannot affect the battery in such a way. The BIOS update you are referring to update the batteries firmware. That crucial piece that lets hardware actually work?

hp nc6400, 4+ years old, original battery, same run time length as always. been running w7 since i got my hands on the first leak.

battery issues? not a freakin one. run with battery in on ac? sure, all the time. random charge/discharge/full charge cycles? check.

pretty much everything they say not to do to a battery, i've done, short of stabbing it, dunking it in water or shorting the terminals.

my take: short of the os glitching and assigning a faulty value to the battery serial number in the registry, it's either the power regulation software just deciding to be stupid and saying 'nope, this ain't right, even though it really is' or the batteries are worse off then people think (note: new != perfect, some will have flaws)

why so? as it's been pointed out, the hardware controls the battery, not the os. there's actually a specific set of circuits on the motherboards designed to check, monitor and regulate the battery charge level depending on wether or not it's on ac or running off the battery. os interaction? all it does is look 'oh hei, batury at #%! hay guis, lukit thiz!' and if it's read as a value below the given threshold, it starts whatever action is programmed.

i have, to date, had maybe 4 real issues with w7 beyond my finicky dislike of the ui layout in places*coughexplorercough*

honestly, it's either a really stupid software glitch thats fubaring the way it's reading the battery charge, or it's pebkac.

Guess which one my money is on in most of these cases.

YMMV.

I have a Toshiba Satellite which came with Vista but I did a clean install of Win 7 Pro x64. No problems for the first 3 months, but now the "consider replacing your battery" notification is always present. Used to get 4+ hours life out of my battery, but now a full charge gives me 56 min. Go figure...

Btw, you can always go to Device Manager and disable the "Microsoft ACPI-Compliant Control Method Battery" listed under "Batteries". I don't know how much good it will do, but it will remove the error message. Unfortunately, once disabled you can no longer determine how much battery life is left. Nonetheless, just a suggestion...

That won't stop your battery from dieing. Either.

Did you try my technique that I posted? If not, try take out your battery and put it back in then boot up your laptop while it is facing sideways or upside down even. Believe me, this might sound silly, but after all that trouble, I'm sure trying this won't be as bad. It's worth a try.

Here's another interesting thread with eerily very similar stories:

Windows 7 and the battery error "consider replacing your battery" (Part 10)

One of the posts read:

"
I have COMPAQ PRESARIO V3000 laptop. My laptop is just less than a year old.
My original OS is Windows Vista. I used to have 4 to 5 hrs of battery usage until I upgraded my OS to Windows 7 Ultimate.
From the original 4 hours of battery life, I ended up having less that 20mins of battery usage.
I am also experiencing that error where in it displays an X on your battery and says that "Consider replaying your battery"
Can Microsoft be responsible for what happened to our batteries? It is unfair for users to spend money in buying new batteries that will later on display the same problem.

NOTE: My brother is using the same brand and model of laptop as I am. He is using Windows Vista and still enjoys the 4 hour battery life.

PLEASE provide us some answer. What can we do to fix this problem. It is even better if you will replace all our batteries!"

Replace your battery or talk to the original manufacture of your computer. The battery says it is dieing so there is only one logical solution, replace the battery. Why is that so hard to understand?

Quote from the link I pasted above: (could be a viable workaround)


"Appears to be a problem with Windows 7.
I found out that the following steps, revived the battery, which is possibly caused by a buggy ACPI in Windows 7.


Running Windows 7 32 bit, getting 30-35 minutes of battery power when AC is disconnected.
Disable the Microsoft ACPI-Compliant Control Method under BATTERY in the device manager.

Put the computer on HIGH PERFORMANCE (I get approx 2 hours of battery life before it shuts down on HIGH PERFORMANC.....Eensure Screen Dim, etc are NEVER) and start running Scandisk (Sector errors scan), Virus Scan, defrag, anything to make it quickly die.

When it has died and there is no power left, remove the battery for a few minutes, press the power button, put the battery back in and plug the power plug in and started the system up.

When windows loads, enable the ACPI-Compliant Method.

BatteryCare (cool program) should now be showing a FULL total capacity, rather than 1/3 or less that it was previously. There is also no Wear Level now (for me), it is saying 0.00% - previously it was 63%.

Since the power on, there is no X over the power icon, its acting normally.

Buggy ACPI - perhaps doesnt charge further than 40% and therefore the warning appears? Doesnt recognise that there is more to charge?

Either way, this fixed my issue and I could then use it for 2 hours, it told me two hours and no longer died at 30 minutes. " - Damian18
