Re: M90Z flickering/blinking power button

Hi @chuck1234


Welcome to Community Forums!


does it stays on and flashing or does it flash for couple of times then turns off?


Lets try these steps:


Method 1

  1. Unplug the power cable from the wall outlet.
  2. Hold down the power button for at least 15 seconds.
  3. Reconnect the power cable and try turning it back on.

Method 2

  1. Shut down the computer.
  2. Tap F1 repeatedly right away right after hitting the power button to turn it on.
  3. were you able to access BIOS ( if yes hit  or Fn+F9 and hit yes to set BIOS to defaults to the same with F10 to save changes ).

Method 3

Reseat ( removing and then putting it back into the same slot ) the parts listed below by follow the steps from this link as your reference.

  • RAM/ Memory Card/s (Page 77)
  • CMOS battery (Page 78)
  • Hard Drive (Page 80)
  • Optical Drive (Page 81)

Let us know how it goes
