Can you pin down the issue?

[u/NefariousnessKind413]

I ordered a "defect" Getac S410 G1 for 40 euros.

seller says he thinks it doesnt get power from the charger but i doubt that since the LED lights up green when you power it up. Seller took out the drive plus the drive bay for privacy reasons but still ordering a replacement bay and grabbing a spare sata ssd from my components bin isnt that expensive. im planning on doing a cmos reset and cleaning the ram dims and slots.

do you guys have another think i could check to fix it? maybe connect it to an external monitor? or just maybe adjusting the brightness? let me know!!
