Question about Lenovo ThinkCentre M52 PC Desktop
maybe i could add some interresting aspects...
a nvidia quadro 1700 card was build in a M57p, i had to replace the sysboard in case of a problem of the rear-fan thermal control.
finally, the nvidia card sended video signals spontaneusly. (sometimes it does, but mostly not, after starting the system the next day)
the funny thing is, i replaced the nvidia card with a similar new one, now the card doesnt work anymore - no output.
today i tested the new one in a M52 8113-cto-System and got the beep code 4 2 3 3 and - of course - no video signal from each output.
I think, this depends on a biiiig problem with all lenovo power supplies. ^^ They really must be overestimated. For example, my pcie-card nvidia quadro 1700 demands a 500W PSU, but the most powerful Lenovo PSU you could order for such a machine only provides 310W. The Power must be much too less!
this really sucks!! but i'm glad to hear, that another people have the same problem.
