Help - not good with computers. Troublesome battery on laptop?
Hi there,
First off let me apologise. I am RUBBISH with computers.
I have an acer aspire 5535. Its about 2 years old. I installed windows 7 about a year ago. I have noticed a couple of problems just recently.
First off, I noticed my laptop was not holding its charge for very long when unplugged. (I must admit I used to keep it plugged in over night which maybe why it is so worn out now).
I then began getting notifications telling me I should consider replacing my battery.
I now have to keep it plugged in when I want to use it. When I unplug the charger the battery life lasts for 5 minutes - literally.
The battery symbol at the bottom right has a red cross in it and when I hover it tells me to replace my battery.
Also I find that it overheats quite quickly now and it gets quite scarily hot so I tend to turn it off now and again to let it cool down.
Is this just a simple case of getting a new battery? Does anybody know where I can get one from? I don't want to buy a random one of the internet because I really don't want my laptop to break.
Also
Earlier today I was looking on the internet trying to solve the problem myself. I noticed on a website somebody having a similar problem and somebody had replied telling them to run command prompt. I followed the instructions for an "energy report". On command prompt it told me energy efficiency problems were found. 4 errors, 8 warnings and 15 informational. I then opened the .html. and this is what it told me:

Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.

Obviously this means absolutely NOTHING to me. Can anybody help? Thanks so much!
