I have a hp pavilion g6 2201ax laptop which came with Windows 8 preloaded. I wish to use a linux system on it and I have installed Ubuntu 13.10. I have found after installing ubuntu that I have encountered 3 problems.
Dual booting problem
When I installed Ubuntu and restarted my laptop, it booted into the win 8 os. Now every time I boot my system it boots by default into Windows 8 . I have found that if I want to boot into Ubuntu then I have to go into bios and have to select the required drive.
This is seriously the worst problem of the 2 I have to face; when I boot Ubuntu, my laptop fanspeed increases and is constantly on. As a result of this in a few minutes (10-15 minutes ) my system tends to become overheated.
Also if I plug out my AC adaptor and use it with my default battery then my system only lasts for 30 minutes while in Windows it lasts for around 3 hours.
How can I fix these three problems?
