Hi

Laptop turns on, no picture, the fans do not spin, after cca 10 sec laptop goes off and after cca 10 sec again goes on and repeating endlessly. Maybe bios is in problem.

Please help.

Thank you

Request the bios inside the dedicated bios forum for this unit.

Remove all power. Measure the resistance to ground on each and every inductor. List the details of any suspects with a low resistance to ground. Each inductor is linked to a local switching power supply. Perhaps a shorted part on a power rail.

Share the silk screen markings of your logic board. My database shows NMD041 and NMD191 as options used for this chassis.
