I’m having a serious issue with my gaming laptop (Medion Erazer Deputy P60).   It started with Windows boot looping. The laptop would reach Windows, then restart repeatedly. Sometimes, after waiting a few minutes, it could boot to the desktop before restarting again.   Trying to fix possible overheating, I: * Disconnected the battery * Removed the heatsink * Cleaned old thermal paste with isopropyl alcohol * Applied new thermal paste * Reconnected everything carefully After that, the problem got worse.   Current behavior: * Laptop powers on * RGB lights turn on * Fans spin at full speed *No display at all (black screen) * CPU remains **cold** (no heat buildup) * After some seconds, the laptop shuts down   I also tried: * Disconnecting battery + CMOS battery reset * Different RAM positions * External monitor   ➡️ No change.   Before thermal paste change, it could at least boot into Windows sometimes. Now it doesn’t pass POST at all end shutdown  Config: Medion erazer deputy p60  I5-12450h Rtx 4060 Ram 16Gb ... Mehr anzeigen
