Hi hope someone recognises the symptoms and can identify a fix?
Lenovo E530. i3 3110, no discrete graphics, new grease applied.
When power button pressed the laptop appears to make the right noises, but restarts 3 -4 seconds later with a continual boot loop approx 10 reboots before shutting down.
Pess the button again and the same happens.
I,m thinking the mobo shorted somewhere?
Checked motherboard for signs of short, eg usb ports for bent pins etc.
Board looks clean.
Thought bad RAM, when RAM is taken out of the board the laptop will power on without restarting, so I'm onto something?
.Used known good RAM..no different regardless of slot position.
Checked the ram slots for debris, appears ok
checked the ram in another computer work fine.
which makes me think the problem isn't a visible short
Done some multimeter diode mode checks on the power rail coils and
Vcore coil is only 3 ohms while CPU is in the board, took the cpu out and low ohms disappears. I,m fairly new to diagnosing laptop faults and would like to know if the low ohm reading is normal for 3rd gen i3 processor?
Any help appreciated
