Guys this is related to my Battery problem that i posted before...correct me if Im wrong but I noticed my Battery Drivers...

I opened Device Manager and clicked on the Batteries and noticed that there are only 2 drivers there:

1. Microsoft AC adapter
2. Microsoft ACPI-compliant Control Method Battery

those are the only drivers that are in Device Manager...correct me if im wrong but there should be 3 right? the Microsoft Composite Battery?...do you think its the reason why Im having trouble with my battery?

This might not work but you can restore the laptop to it's default factory settings and see what happens(after backing up your data of course)

well I just finished Recovery Area...and its still the same...is it safe to assume that Microsoft Composite Battery is 'bundled' with Microsoft ACPI in Windows 8?,im not sure,but I read some articles about that...

I don't know what the problem could be but you could contact tech support on the official vendor website or visit the forums there.

You're being sub-par in the intelligence department.

Lithium Ion batteries don't respond well to draining halfway and then being charged again.
It's not how long you've had it but how many cycles you've put it through, this is normal wear and tear, no battery lasts forever.

If you want to be cheap, go back to the store and get it replaced.

Don't believe half the crap people tell you here, in regards to your other post the poster who sheepishly wrote that your laptops cooling system operates separately from all other components was the biggest load of crap I've ever read. You left your laptop on in your case, potentially damaging it. Your fault. If you had shut it down correctly, there's no way it could have ever gotten hot, and even if it did, no way for the fans to turn on.

Also, a Sony Vaio is the shittiest model and brand you could have ever purchased.

Good day.

duh? lmao...just so you now,i know everything about li-ion battery life cycle...lmao...thats why I asked why my battery suddenly went dead in just a day...if your battery becomes dead,it would SLOWLY DETERIORATE,meaning in a span of couple of days or weeks you could see the deterioration...but my battery was working great for months,and held an average of 3.5-4 hours...then suddenly ONE DAY,it could not reach 100%,just like that...and next time when you try to comment,stop being a bitch...

Good day

Buy yourself a new one.

Like with car batteries, the only cure for a bad battery is . a new one.

There is no need to insult people who come here asking for help. I'm sure there was a time you yourself didn't know the answer to his problem but that didn't make u any less intelligent.

I am not familiar working with windows, but in that link I gave you they also directed to this page.
maybe there is a similar troubleshooter in windows 8?

months,and held an average of 3.5-4 hours...then suddenly
ONE DAY,it could not reach 100%,just like that...

my battery never reaches 100%,it stays at random percentages..like 65%, 73% ,79% etc...so basicaly the battery lasts only 1.5 hours now...and when it discharges at about 24%,it suddenly goes down from 24% to 10% or 7% in just a minute...and my other question is I just noticed that 'MICROSOFT COMPOSITE BATTERY is not included in my battery drivers in Device Manager,there are only 2 drivers under BATTERY...there should be 3 drivers there right?

well thats what im planning to do or maybe just buy a UPS,but my concern is there is no MICROSOFT COMPOSITE BATTERY in device manager,as far as I know there are 3 Drivers under the Battery right?...or is it different in Windows 8?

I won't consider it a driver problem. The problem is solely with the battery. It's dyeing.

yeah,aryt...but how about MICROSOFT COMPOSITE BATTERY in Device Manager? is it really not in windows 8? cuz my other laptop with Windows 7 has 3 drivers under Battery...and this laptop only has 2,which are the Microsoft AC Adapter and Microsoft ACPI

I'm quoting this reply from the link provided...

'The Microsoft Composite Battery Driver (MCBD) does not have anything to do with the battery charging or not charging. The charging function is controlled by the Hardware Charging Circuit that is a part of the Motherboard installed in the laptop.
The only thing that the MCBD does is report the information that it receives from the charging circuit. This information is displayed in the Battery Meter GUI that is located in the Desktop / Notification Area.
If you can see the Battery Meter, this means that the MCBD is working OK.'

yeah already read that before...im just confirming if that's how it is for all Windows 8...thanks
