I am new to Ubuntu. I have installed wubi.exe for 12.04 LTS on my D: drive. Problem is when the login screen comes up at booting, my power adapter dies. If I unplug and plug it again immediately, it doesn't work. It only starts working when I plug it back after like 5 minutes. Another problem I am getting is my computer heats up a LOT while running Ubuntu. And after running for a while it shuts down unexpectedly. I am not sure if it is for the temperature sensor, because I did install lm-sensor the last time. Still it crashed.
My laptop is Samsung, Windows 7, Processor: AMD-A6-3410 APU with Radeon(tm) HD Graphics, 6GB RAM
