Solved! Thinkpad t430 power button turning off and back on by itself when booting

[doantientai94]

Hi guys,

My laptop (Thinkpad t430) power button is acting so strangely. When I press the power button, it lights up then off immediately, and after about 3 second it starts to boot the system.

I recorded a short video of the problem: https://photos.app.goo.gl/iaj9vPyD9NacLSfJ6

I don't know if this is a problem of the CMOS or it is because the button (which goes with the keyboard) is malfunctioning. What should I do to get it fixed?

Thanks a lot for your attention!

remove the HDD
try booting with only one RAM module (switch slots)
try booting without main battery and only the charger
try booting withouz the charger and only the main battery

Thank you for your reply and sorry for late response. I tried removing the HDD and the problem is actually gone. It seems the HDD caused the problem but it is not completely broken right? My HDD is in a tray in the place of the DVD reader at the beginning. I started to use this HDD for 2 years, but the booting problem is recent. What should I do next?

check if the HDD is working again in the tray, maybe it was just a connection fault.

check the HDD in a different system
