Hello,
====================
EDIT:
1. SSD -- tests good
2. power supply -- replaced power supply
3. motherboard -- replaced motherboard
====================
I am running Arch Linux on a Lenovo 6072 ASU ThinkCentre M57.
Recently I have noticed a problem with the power switch. At least I thought that's what it was. Sometimes when I powered the computer ON, I would hear a 'click', the fans (case fan + video card fan) would roll over and then they would stop. (This is the same thing that always happens when the power cable is first plugged into a wall socket even without the power switch being pressed.) Pressing the power switch a second time would allow the computer to start properly.
Yesterday, I shut down my computer in preparation for installing about a week's worth of updates.
When I pressed the power button, I got the click, the fans rolled over, and then stopped. Pressing the power button again repeated the process, but the computer would not boot. It never got to the point where a signal was sent to the monitor. I never got a motherboard beep code.
I tried pressing the power button again but this time after the fans stopped, they started again... and again... and again. Wiggling the power switch had no effect. I had to pull the plug on the power supply.
Then I started disconnecting hardware, one piece at a time, and plugging the power cable back in. Eventually the fans stopped, but now after plugging everything back in, nothing happens. The fans don't spin up. No signal is sent to the monitor. I don't get a motherboard beep.
The power supply has two lights on it: red, green. When it is plugged in, the green light is illuminated. The red light does not come on.
So I figure either the power supply or the motherboard is shot (or both).
I removed my solid state hard drive. I booted a Windows 7 machine by using my Arch Linux .iso (a couple of months old).
The drive does not appear with lsblk.
From root@archiso I looked at dmesg. Then I plugged my SSD into a USB port by using an Apricorn USB converter. Then I looked at dmesg again. The green LED on the Apricorn illuminates for about 5 seconds then turns OFF. When it turns OFF the following is written to the terminal:
dmesg
[ 44.831581] sd 7:0:0:0: [sdc] No Caching mode page found
[ 44.833646] sd 7:0:0:0: [sdc] Assuming drive cache: write through
[ 86.273468] print_req_error: I/O error, dev sdc, sector 0
[ 86.273468] Buffer I/O error on dev sdc, logical block 0, async page readSo... is there any hope for this machine, and more importantly, is there any hope of getting the data off the SSD?
Cheers,
====================
After researching some more...
it looks like the first two lines in the dmesg log at [ 44.831581] and [ 44.833646] are normal. The last two messages at [ 86.273468] and [ 86.273468] are the result of (not the cause of) losing connection to the drive.
I think the problem with the drive not showing up with lsblk is that I don't have whatever drivers I need for the Apricorn. I have a second enclosure which allows a SATA drive to connect via USB. I disassembled the enclosure and swapped my drive for the drive which came with the enclosure.
Now I can see my SSD and mount it. All my data look good.
Next step - purchase a power supply tester! Should be here next week.
====================
The power supply tested good, so I purchased a new motherboard.
Unfortunately it also would not boot.
Purchased a new power supply: it would not power the old motherboard, but it would power the new motherboard.
Cheers,
