From now it’s pretty easy. You just need to disaasemble battery (big black). Unscrew and delicatelty take out connecting cable. Keyboard cable should probably be under some tape – you will recognize it by my earlier pic.
I’ve already wrote to seller asking if he has it and asking for some picture. Will write to Gearbest as well with your suggestions.
This Bmax Y11 looks nice, but what is really difference with F5?
BTW – if I were you I would do some backups. My disk has failed after about 5 months
