Laptop shuts off when it takes any kind of small impact

a few months ago i dropped [URL="http://shop.lenovo.com/us/en/laptops/thinkpad/yoga-series/yoga-14"]my laptop[/URL] and now even if I put a little pressure with my hands on the casing of the laptop or tap the laptop on a table when i put it down it sometimes just shuts off. kind of like if you just unplugged your desktop from the wall while it's on.
it's getting pretty annoying since it's obviously an unsafe shutoff and it takes a long time to boot up again afterwards.
i've tried taking off the back of the laptop to see if anything was wrong with the battery or fans but i don't see anything visibly wrong with them.
does anyone have any ideas why this happens?
My old PC used to do this but that was because the motherboard was physically warped.
Could be a hair line fracture - Same thing happened with one of my laptops years back. It would turn on if I held it in a certain way, but power off as soon as I released pressure.
It could also be that the drop may have either affected the mobo, the hard drive, or the connector to the hard drive.
First make sure those parts are all looking fine and don't have any dings, scratches, warping, etc. If you find an issue and unless the mobo is to blame, you can easily replace the part(s), but if it is the mobo you're a little out of luck unless you can find a mobo for it.
You can also try checking the S.M.A.R.T. data of the drive, and try using either Seagate's or WD's toolkit to test for errors.
A hard drive going bad does not cause a computer to just power off. Surely you could check the drive which likely does have damaged sectors if it was powered on during the drop, but I doubt it would do any good.
The motherboard having a hairline fracture somewhere along the connections sounds like a likelier cause. In that case you would have to get an experienced repair shop to look at it and reflow the board. That's usually really expensive however, so it would be either getting a new motherboard or just replacing the laptop altogether.
Hairline fracture within the PCB is not something you can fix by reflowing. Chances are op will need a new board altogether
