I can tell you that it's a Torx bit, but it's hard to see what size it is and I can't find it online.

But I would guess the bit size is somewhere between T3 to T8.

Update

Thanks for the documentation, they are M2 Torx4 (T4) screws.

From my understanding, the "L" just means that it's one of that L shaped tools normally used for Allan/hex keys. So a normal T4 bit should work without any problem.

I updated the range of bit sizes, I started thinking about this answer after closing the computer yesterday and the bit sizes I wrote were probably way to big.

Sorry if that confused anyone!

Appears to be a Torx. Probably somewhere between T5 and T9. I'm not seeing a pin in the center, so it does not appear to be Torx Security.

Mohammed Musa you are right. No teardown or guide for it yet. Download the maintenance manual for it from here to work on it. While you do so, create a guide for the next person that may need one. It's really easy to do and will help https://www.ifixit.com/Guide/new the next person.

Yes, the screws are regular TORX screws. Those are M2 screws so I expect it to be around the T3 to T5 range.
