After the Dell tech replaced the board I had no problems booting up on my F16 installation. After a few days this motherboard started exhibiting power supply issues. The system would switch from AC power to battery, dimming the monitor, and then switch back to AC with the monitor brightening. This continued to happen on and off for several weeks, it also would happen under Windows 7, so wasn't an OS issue. I tried two different external power supplies, but the problem still occurred. If I took the battery out and ran on just the AC then the system would power itself off within a minute or two. I contacted Dell and described the problem and today the Dell tech replaced the motherboard again. The problem is that now Linux no longer boots. It starts to boot, it loads the kernel and the ramdisk, but then the fan speeds up and the system powers off. Earlier today I was able to boot off a F16 DVD and was able to backup my user account data to an external drive. Now when I try it it no longer works, it starts the process, I get prompted for language and keyboard, but then again the fans speed up and the system powers off. The system is configured to boot both Windows 7 and Linux. If I boot Windows it comes up just fine and runs, but Linux wont. When I boot Windows the fans do not speed up as they do with Linux.Anybody have any ideas as to what might be going on?The system is updated to the lasted changes. I tried to boot an earlier kernel, but I get the same behavior.
Any help is appreciated.Thanks,PaoloI'd try, the problem is that booting from a Fedora 16 DVD also causes the system to power off :-(Paolo
I can see at least two possibilities:
1) The F16 DVD is defective. I'd check it somewhere.
2) Your hardware is defective.
Beyond that I am not sure what to say at this point. Sorry...
Boris.
