Power problems

2020-09-26, 8:46 AM

I have a Ideapad S145-14IWL 81MU and when I power it on a short time later, between 30 to 60 seconds it powers off then back on by itself, I replaced the SSD and it still does it, I go into BIOS and it does the same thing, I try to install windows on new SSD and it does it. Any help would be greatly appreciated

Hello,

 

You should consult a PC repair technician.

 

It seems you can reach the BIOS screens, but even there with those screens showing, the machine powers off after 40 seconds?   If you can a good first step would be to reset BIOS to factory default settings.  Usually that toggle is on the same screen as the save changes and exit button.  Also, is it really off, or did only the screen lighting shut down.  Will brightness UP do anything useful? 

 

A simple thing to check is whether the cooling air inlets and outlets are blocked.  If so, unblock them.  Then perhaps support the PC spaced farther than normal from a hard surfaced table top, to allow free circulation of cooling air into the PC and hot air out of the PC.  For cooling to happen, both processes have to happen, "cool air into" and "hot(er) air out of"....
