Solved How To Replace A Power Switch Button On Thinkpad T540P Laptop Lenovo Thinkpad T540P

Chosen Solution

Power button will not turn on nor shut off my ThinkPad T540p Lenovo laptop. How can I fix this issue? Thanks!

Hi @tomenews42 , Here’s the hardware maintenance manual for the laptop. Go to the bottom of p.75 to view the necessary pre-requisite steps and then the procedure to replace the power button board. To find a replacement board search online for 04X5553 to get results for suppliers that suit you best. (A W540 is the same as the T540p as far as the board goes)
