Do you have any advice for cleaning the keyboard on the Lenovo Yoga 3 Pro? One of my keys isn’t travelling as far as it should be; I believe there’s something tiny blocking its path. I have a good feeling that I’m not meant to rip the keys straight up and out. So it’s really unfortunate if I have to completely tear down the entire machine just to clean out the keyboard. Thank you if you have any advice on this.
Does anybody know where I can get a replacement fan for this? Everywhere I’ve looked, they only seem to stock fans for other models.
How did you disconnect the screen? Thanks in advance.
My Lenovo Yoga Pro 1370 stopped working, and I was told it’s the motherboard that needs to be replaced. Do you know how to replace it? Is it ok to do it, or is that the end of my laptop? Thanks
Is there a CMOS battery at all? I cannot locate it and am having to reset the whole battery to reset the BIOS. I hope this works. I cannot remember the Windows password or the system password, so I can not log in at all.
