  1. Please help me.

    How easy is it to replace the keyboard?

    And how many slots does it have for the RAM?

    Thanks in advance.

    1. ThinkPad Yoga S1 has no RAM slots; the RAM is soldered to the motherboard. You can try to replace the keyboard and write a replacement guide. I can give you a contributor account, and you can publish your guide on our website. Thank you very much!

  2. I messed up and forgot my BIOS password. I tried removing the CMOS battery, but it didn’t clear the password. Does anyone know if there is a jumper?

    Thank you

  3. How do you remove the LCD rear cover assembly? I have damaged one corner and would like to replace just the plastic cover if possible.

  4. I have an S1 with a basic 128GB SSD. I can see the empty mSATA slot. Can I just connect a 128GB mSATA (or must it be M.2) card for additional storage, or are there other changes I need to make? I see many 42cm mSATA/M.2 cards available. Is there a particular (recommended) p/n or model I should use?
    Thanks!

  5. I collect ESI for legal purposes. Popping hard drives and conducting a physical collection on these drives is much more efficient. When attempting to pop the SSD in a Lenovo ThinkPad Yoga S1. I discovered that the screw was stripped when the factory installed it.
    Any suggestions?
    Easy out? Not sure if the drill bits are small enough.

  6. Hi, I need to open the bottom cover to replace the fan. What’s the trick after I have removed all the screws? I don’t want to force/break anything.

    Thanks.

    1. You need to insert the pick under the bottom cover and move it along the edge to unfasten hidden latches. You’ll have to apply some reasonable force in order to separate the bottom cover from the top case.

  7. Hi,
    I would like to update the SSD from 256GB to 512GB or a 1TB SSD in my S1 Yoga. Are there any recommended SSD models that are compatible with the S1?
