Lenovo unexpected shutdown// suddenly shutdown become polular

Hi everybody, I'm a electric/computer engineer.I come from Viet Nam and I have Lenovo T420s (from US) . On a beautiful day, he was silent when I touch he. Ahh, he was binky the led on power button. I serach on GOOGLE, and I bring he to maintance computer shop. They say power IC die, and they replaced with another. I think they do nothing because when I turn on my T420s, he ON, and he unexpectly/suddenly shuttown after about 25-40 mins in every case ( in win, in bios setup or in anything) but if I take restart he before 25 mins...he work over "die" time. I search and I dont know what was wrong with him. I love him, tell me what I need to do to bring he back please. Thank you.

Hi Kim_perfect_712,

 

Welcome to Lenovo Forums!

 

I appreciate the troubleshooting steps done, but as per the performed troubleshooting steps it seems to be a hardware issue and it looks like motherboard has gone bad. As you have told the laptop automatically shut down in BIOS, it clearly confirms that this is a motherboard issue. Hence I kindly request you to take the laptop to the authorised Lenovo service centre for the further assistance and you can get him back workingSmiley Happy

 

For your reference, please find the link given below to find out the authorised service centre according to your location.

Click here to open a link where you can select the country and get the exact contact support number. I’m sure they will be a great help.

Thank you, have a good day.
