Ace Aspire 5672 battery causes keybd and touchpad malfunction

[Koofah]

I upgraded my Acer Aspire 5672 from win xp to win7 hm prem 32bit. I realised that the keybd and touchpad fails to function when I have the battery unit installed, but they work fine as soon as I remove it. Before the upgrade, I run the microsoft upgrade advisor program and it did not flag the battery.
Secondly, I dual boot with ubuntu 12.04 and the keybd and touchpad works well in the ubuntu platform except that it receive very minimal charge. The laptop runs on the minimally charged battery for a short period.

Hi Koofah. Welcome to the forum.

Unfortunately, you are going to need to replace that battery. All batteries have a limited lifespan. When they will no longer charge fully they are finished.
And when they are dying a laptop can exhibit many strange behaviors.

The fact that everything works normally on power supply with the battery removed is proof positive.
