Y40-80 Gaming machine / keyboard replacement

2017-12-20, 5:51 AM

Hi, All!

 

I am about to attempt to swap out the keyboard on my Y40-80. Tonight I did a test-run and man is it tght in there! 
It looks like I will have to remove the motherboard, fan array, HDD, 1 speaker, heat sink, etc. to get to where the keyboard is located. Furthermore, after reassembly, the function+adjust volume only goes up and the function + increaes brightness no longer works. 

(Perhaps ths is because I left few screw off the motherboard to make it easy for when I actually attempt to replace the keyboard. )

Has anyone on here attemped a keyboard replacement on a Y40-80 ?

 

Thank you!

Thank you. While this is very detailed. It does not specifically address how the keyboard is to be removed and replaced.
Please advise.

Okay, I think I am getting the picture. It looks like I am required to remove every component + the LCD--or nearly every component + the LCD--to replace the palm rest keyboard on the Y40-80. 
Does this sound accurate? 
I just purchased item #5CB0F78626. 

Is this the correct item?

Do you have any idea why I can only adjust the volume upwards and the screen brightness downwards at present? All other keys are working, however my 'A' key is failing.

 

Thank you again for your time and attention.

I didn't actually check the documentation but you should've changed the keyboard without dissembling the all system. Make sure you connect the keyboard cable well and check the key if it's stucked. It may be just a keyboard issue as well - you may need a replacement

Based on the documentation you provided, it does not appear to be possible to change the keyboard without changing the entire "palm rest" which includes the keyboard. 
Based on the documentation, this appears to require disassembly of all components as the keyboard/palm rest are inaccessible without having to remove the:
Speakers

Fans + Heat Sink

Motherboard

HDD

Battery
Video card

Audio card
WIFI card

I/O card.

Does this sound correct? 
Can you please confer with a colleague to provide specific instructions regarding keyboard replacement of a Lenovo Y40-80 ?

 

Thank you.
