My laptop runs on Windows 7 and is a HP Pavilion dv7 - A6S17UA#ABA
Lately my laptop has been freezing on me. When if freezes the f12 or wifi blinks between white and orange. The only way t o unfreeze it is to restart the computer. I did this for a while to circumvent the problem but twice after rebooting the computer wouldn't start up normally and I had to do a system repair which led to a ststem restore. However, even after a system restore the problem is still happening.
Is having my computer plugged into the power cord most of the time the cause of this problem?
Also, the screen darkens on its own when I'm on dark webpages then lightens back up on bright ones. However, this only happens when the power cord isn't plugged into the computer. What is casuing this?
