Thinkcentre M90p - Desktop wont turn on / Powerswitch doesnt work
I own a Thinkcentre M90p - Ive only added a NVIDA quadro 4000 and 16gigs of ram to the stock product.
The computer just wont power on. I replaced the mother board, and the small battery inside the motherboard.
I hear a spark when I plug the power cord in the back of the tower, but when pressing the power button, nothing happens.
Thats my board with nothing plugged,
This is the two pin out of the speaker/beep
This is the three socket coming out from the PSU
There is a three pin wire coming from the PSU that Im not sure where to plug in, or the 2 socket coming out the speaker/beep speaker.
Im not sure what i can do to get power working. It was working initially, until I plugged the three pin into the power_fan on the mobo next to sata 1. I do not have a volt meter to check if power is coming out the PSU. Is there anything I can do ?
Es esta una buena pregunta?
