Is there a way possible to run a laptop only on AC power without having the need to remove the battery i.e. to disable the charging as it is possible in Windows 7.

Just a note, Windows 7 does not have the option to disable battery input, nor does it have the option to disable charging reliably. – Thomas Ward Feb 8 '12 at 21:11

I think the only way this is possible would be on a hardware level. I've never heard of a laptop that had this as an option, though.

In Windows that is probably done by a driver for this purpose. Something like Smart Battery in DELL laptops. Not sure if that will be an option for your laptop, check the builder's website.

I needed a solution for this because my battery life is going down so i want to save it from degrading further due to over charging. – Vinay Feb 10 '12 at 7:00
You just remove the battery. There is no other solution. – gajdipajti Feb 10 '12 at 9:00

According to How to charge the battery till 60-80% only?, you can use Dell's Airplane manager to enable airplane mode so now the laptop will not charge the buttery and run off AC power instead.

You can install it from ppa:opensource-subakutty/ppa, but personally I couldn't manage to install it on a 64-bit Trusty machine.
