problem with small factor thinkcenter.

[Evert]

Hi ,I am new here.
Hope to find the answer to my problem.
I have a Lenovo small form factor model B2U,machine type 4163,prod id 4163B2u.
My pc was on when I left home.When I came back the monitor was black and the front (round)power led was off but the cpu and ps fans were still running.I hit the pwr button to shutdown.I waited couple of minutes and tried again.No luck,just blinking of pwr led.
I disconnect from ac oulet and tried again ,no luck.I went out of the room and when I came
back after 30min I saw my pc working.Then next morning I took the pc to the shop,it denied
to power up.I took out the ps checking for cold solder joints and bad caps.No bad joints and caps measured ok.My question,did any member experience this problem ?
A intermittent ps problem.
