While not familiar with the specific laptop, I had a similar issue with an application which used the MAXIM8724 controller IC.Battery-in positive and ground line shows shorted signal in multimeter but in power jack side positive and ground is not short.
It does not sound like the same problem I was referring to earlier. Getting too involved in SMD computer motherboards can get very frustratingVtech thanks. We found pc92 and pd3 were shorted. After replacing these components this motherboard litup everything like normal but after some minutes all the light gone again. Please help
This is just some information chucked in gratis, but a computer which suddenly blacks out, as you mention, is often due to one of the chips overheating, normally the CPU.Cpu, North bridge and South bridge were found very hot. I think its normal but suddenly blackout. Thanks for your help vtech
