There is a RoverBook Navigator B510W
When you press the power button, the power indicator lights up,

, the HDD indicator goes out (this cycle usually repeats several times ), then silence.

in terms of symptoms, it looks like a video chip, only rebowling will save ...
it is either soldered or shorty from overheating.

Faced, though on the Sony NR-31SR. The problem was solved by simply pulling out and inserting the battery from the laptop.

Answer 3

no battery, bp 100% working.

yes, repairs will cost 6 thousand rubles.

Answer 6

try connecting an external monitor, maybe the card is intact,
