HP G62 plugged in, not charging

[leadbelly]

Hi,

I have a HP G62-107SA , running Windows 7

My laptop is about 2 years old and in the last few days the battery has been causing me problems. First the laptop would shut down when the battery level was at about 30%. I tried to calibrate the battery but it still says on HP support assistant that it needs to be calibrated. I then turned off the laptop, removed the battery, held down the power button for 30 seconds, put the battery back in, booted up and reset the power plan settings. This seems to have solved that problem but now the battery does not charge fully. It charges to about 75 - 80% then its says "plugged in, not charging", I then shut down the computer, removed the battery and started it with ac power, i then uninstalled Microsoft ACPI Compliant Controll Method Battery, shut down the computer, unplugged the AC power chord, put the battery back in and started the computer on battery power. I then left it running for a few minutes shut it down plugged the AC power chord back in a started the computer again. The battery started to charge again but stopped charging at about 85%, 5% above what it was before. I repeated the action and got another 5% or so and again until it fully charged. Once fully charged i unplugged the AC power chord and let the battery drain to about 70% then charged it to see how far it would go and it fully charged. When i used my computer today the problem had returned and have had to repeat the action all over again to charge the computer, i am currently at 82% and cannot be bothered to do this every day just to charge the computer.

Can anyone help me fix this? Do i need a new battery or is this a problem with the computer?

Thanks.

2 years is a decent life for a battery. I always say the obvious solution is the most likely and the most likely is it needs a new battery.

You might take a look at this but it looks like you have tried most of it:

Hi,

Thanks for replying so quickly. I attempted to calibrate the battery using HP System Diagnostics which i  accessed by pressing the esc button whilst starting up the computer. I followed the battery test procedure and left the computer whilst it was being calibrated (it took about 4 hours), when it had finished i started up the computer as normal and ran a battery test using HP Support Assistant and it said the battery needs to be calibrated.

Is this correct, did the battery calibration fail? If so what can i do now?

Many thanks.
