My dad's Lenovo Z470 with Windows 7 is shutting down automatically and the time it stays on based on how i start it:
(1) Normal start : in a few seconds
(2) Under Safe Mode, Low resolution (480X680) option : I can get to browse a web site or play a short video ad
I also try the last know good configuration and has the same result as option 2.
I try to remove the battery and ac charger and press on power button for 20 to 30 seconds. Then plug back the AC charger and still shutting down.
I order a new charger and battery will test to see if this is the issue when i receive them.
Please let me know what could be the issue and if you need additional information.
Thanks so much in advance!
