Pls what did you do? Did you change the CMOS battery or capacitor? Which pls?
@r.k.techno24013 жыл бұрын
No I did not change CMOS battery or capacitor, I change Resistor the original resistor value is "33"ohms, I did not have that time, so I put "0"ohm. Thanks for your understanding.

Yo dantee this model probook 4520 and 4440s have a common dc jack LED blinking problem..It could mean 3 things so far..But i have tried all those 3 things and my problem didn't solve..After spending hours trying to get it to stop and power on today..I realized that i had a bad Bios chip...Remove the bios chip and try a good working bios dump for it and try.. I took a bios from another working board and the LED light stop blinking and labtop working normally.. if every other fix fails..you can contact me at djchillsound@gmail.com if u need more help and assistance..Before you contact me make sure you have chip level repair tools so u can remove IC's.
