T440p: missing screw

#1 Post by Peppo » Mon Oct 21, 2019 8:50 am

Hi, I've lost one screw from the bottom of my T440p. I'd like to buy a replacement, but I don't know the exact specifications of the screw.
I found this manual: https://thinkpads.com/support/hmm/hmm_p ... 467_01.pdf

The missing screw is the 1c screw on page 77, but the manual is wrong as it says they are M2 x 3 mm screws, but those are definitely longer than 3 mm in my T440p. I'm not sure about their exact length though. The manual I found on Lenovo website doesn't even mention the screws' specs (https://download.lenovo.com/ibmdl/pub/p ... _ug_en.pdf).

Can you please tell me the specifications of that particular screw (M2x5, M2x6)?
Where would you buy it?

Thank you very much in advance.

I'm also missing a couple screws from my T440p so what I've done is ordered a set of laptop screws in different sizes. You can get this from sites like Amazon or Aliexpress, just search "laptop screws", it's not expensive and you will have a nice set for any future projects/repairs.

@Peppo:
take one of the other 1a/1b/1d/etc. screws out and measure the threaded part.
if 4mm long then you need M2x4, if 5mm, then M2x5, etc.

One of my T500's came with several screws missing. I found a replacement kit on fee-bay from a parts machine. I forget the seller, but he had screw sets from many different TP models.

You might want to just buy a whole set if available. I think I paid around $6.

My conservative estimate is, that I currently have about 2,000 Thinkpad related spare screws, collected over ca. 15 years.
They are sorted by size, not model.
