Power on but no display, the issue happened after changed the thermal grease with battery disconnected. but then after changed the thermal grease and thermal pad, it stopped working now.
Is dit een goede vraag?
1.CHECK BRIGHTNESS AND ALSO TRY TO CONNECT TO AN EXTERNAL DISPLAY.
2 FORCE RESTART, power off the device and then power it on after 15 seconds.
Was dit antwoord nuttig?
It is not brightness issue and connected to external display not function all.
Tried force restart and follow the guide from reddit hold down volume up + power button to reset the device. still no luck, but once it a while the device can be turn on. when i plug in ssd or reopen the heatsink and put back, but now no more luck. i believe may be is due to static electricity or other electric leakage issue, cause the lenovo backplate case the screw see got electricity while charging.
Nobody can solved the issue, many shop not confident to fixed it.
