I repost my related entry from another thread
I began to have this problem after my R500 died on me, went for repair, and was repaired (apparently faulty USB ports. ) the repair guy soldered on other USB ports, he managed to wake up the computer, but the USB do not work anyway.
I restored an old image of my ssd system disk, and the pC worked.
Upon the first boot back from repair, it was unable to boot correctly and stated "error in time and date" or something.
I have entered some fake date, in bios, and then the pC started functioning
However, the soldered USB ports do not work. I am considering some expresscard with USB 3
-however, I started to have the problems described above. PC suddenly going into suspend for no reason.
Also, it seems that the power scheme settings behaved idiotically, i.e. I reset them to Go to suspend: never, and later when I looked, the setting was five minutes.
I installed the latest Power manager, the problem existed, then I removed Power manager.
- I tweaked around bios. Switched off all "clerver" methods of power management, CPU performance regutlation, wake on lan, anyghing that looked a bit sophisticated I turned off
- new chipsed driver, new bios
- TP fancontrol, set on an agressive setting, that is, I am erring on the side of more noise, lower heat.
now standing at CPU/ GPU at 52/40 celsius.
- now I have not seen any shutdown for a while, running on battery. However, this is an intermittent problem. I will see.
The problem occured when I was watching DVD form the DVD drive, and browsing.
- any co
