How to fix a problem with a laptop?

Question

Windows

Product Name: Hp Elitebook folio 1040 g1
Operating System: Microsoft Windows 10 (64-bit)
My hp elitebook folio 1040 g1 won't turn on. When I press the power button it shows the power button, the wlan light and the mute buttons blink randomly along with the keyboard backlight.
The screen remains dark.
The laptop turns on only when I turn it over and lightly hit it a couple of times, only then it turns on. If after that I don’t touch the laptop and leave it as it is, I can turn it on the first time, but if I pick it up or take it with me to work, then there is already a problem turning it on, you always need to turn it over, make a couple of light blows to turn it on . Maybe someone faced this problem? I will be very grateful for your help.

Answer 1

Sounds like a track/soldering issue.
Hit further - it will die completely.
So - to the service, if you do not have a soldering station at home.

Answer 2

Some connector is loose. There, it seems that the battery is integrated into the bottom cover, perhaps its connector will not contact.
Or disassemble and look for or service.
