Hi all. I've got what once was an MSI GE40 sitting here that has had a hard life. I bought it for the screen (14" 1080p IPS panel, that I haven't been able to test yet...) with a dead Mobo.
I was curious how "dead" so I plugged it in and the charging LED lit up. Pushing the power button gave a brief flash of the power LED, then nothing.
And that's my current abilities exhausted.
I don't know the history of this laptop but I can see no evidence of spill damage on the mobo, however the power button board looks like it's seen some action before (see image). If it helps I believe these systems can run very hot.
Please could any one advise on what the next step might be (and maybe how to go about it)? A schematic may help, although I have little experience reading and interpreting them.
Thank you very much!
I was curious how "dead" so I plugged it in and the charging LED lit up. Pushing the power button gave a brief flash of the power LED, then nothing.
- So I removed ram, swapped for known-good, switched slots, tried none. No change.
- Removed and reseated CPU. No change.
- Removed battery. No change. Measured PSU with voltmeter = 19.35v
- Removed all power. Held down power button for 30 seconds. Reconnected power. Power LED lights & fan on full, sits there indefinitely doing that and that only. Power down, and next power up power LED lights for 15 seconds but that is it (no fan), then powers off. And then next power-on, back to the brief flash of the power LED, then shuts off.
- And then next power on nothing at all, just the charging LED lit. No brief flicker of power LEDs, nothing. So I went back through everything but still no signs of life apart from the charging LED remaining lit.
- Disassemble. Unplug everything apart from power in and power switch. Charging LED still lit, but no other signs of life.
- 19.35v getting to 3 left most pins on POWERCONN1 (top left, first photo), 3 pins on right are ground.
And that's my current abilities exhausted.
