What screws do I need for replacing all of T480s internally? M2x3 - m2x4? (programming.dev)

I recently purchased a T480s and after taking it apart to do a badly-needed clean, half the screws inside are missing, e.g. no screw for SSD, only 1 for the battery, various ones for the connections etc.

If I buy a specific set for the T480s, they're like £35, so I'm thinking of buying a large generic set from ali - what sizes do I need though?

M2 x 3, M2 x 4? for both the normal and the 'fat head' shorter ones?

Are there any others?

Also, bonus question, the previous owner did something funky with the screen and the sides don't seem to be pushed in equally all the way around - can I simply just apply force and push the screen into its housing so the sides align up equally, or do I need to actually take it apart?

As far as the screen goes, I advise following the manual in my other message to disassemble and reassemble. I love to push things back in, but breaking the LCD will be upsetting.

lol and the exact reason I haven't pushed in too hard. As it's a new laptop to me (and my current laptop is an aluminium tank) I'm not used to the max forces that can be applied before things get to the 'upset' stage!

Starting at Page 57, there is a part number for screw kits and then replacement procedures for each item with screw size and description

Thanks! I'm not too impressed with the build structure of the 480s compared to my M4800. It's a shame that screw sizes seem to be non-standard.
