I am completely new to Ubuntu and could not find my problem stated anywhere so far. I would really appreciate some help. :)
I am running an Aspire V Nitro (Intel® Core™ i7-4710HQ CPU @ 2.50GHz × 8; GeForce GTX 860M/PCIe/SSE2) with Ubuntu 15.10. Everthing is perfectly fine as long as I have the laptop connected to power. Even if I disconnect the laptop from the powersource and it runs on battery everthing works.
But if i start my laptop only running on battery it is nearly impossible to do anything with it. It lags with every task (open chrome/ firefox) or just using the mouse.
I thought that it may have to do something with the clockspeed of the graphics? Otherwise I have no clue how to fix it.
Cheers
