How to fix the HDD contact in a ThinkPad laptop?

Question

Good time,
I have a ThinkPad T580 laptop, I move around with it quite a lot, at first a BSOD began to appear, after which Windows would not boot. I found a pattern: if you don’t touch it, then everything is fine, but if you walk around with it, then problems arise, and if you gently shake it at different angles, something falls into place and works. I disassembled it, pulled out the cable between the motherboard and the disk, wiped the contacts, put it back in - for some time it worked without failures at all, and the next time, with the same manipulation, the contacts on the motherboard fell off. It was in Bali, I handed it over to the local authorized Lenovo service, they said that they could not solder, and replaced the entire motherboard (ordering it from Singapore). For more than a year there were no problems at all. Now again I caught a BSOD, the boot hangs on the logo, diagnostics at the start gives an HDD error. Also, Gently shook it in different directions - it worked. But it's not clear how long it will take. It seems that the same problem has returned (although the motherboard has been replaced!). What can be done? The option to buy another laptop is not very good (you need a good one, which means not cheap), as well as handing it over to the service (now I'm in Russia), because. constantly needed for work, there is no way to wait.

Rub the contacts with a soft eraser so that the legs do not tear off.
