hp probook light blinking problem

Message 1 of 3. HP Recommended. Product: Hp Probook s. Operating System: Microsoft Windows 10 bit. Please help. Tags 2. Tags: hp probook s.Hi,i have a HP ProBook s with windows 7 home premium. Some weeks ago my ac charger short-circuited and i had it repaired by a local electrician. After he gave it back to me,it worked just fine for a while one week then stopped working completely. Whenever i plug it in,the ac adapter light indicator blinks about 9 times then nothing happens.

I counted my loses and bought a new charger,but it just wont work-I get the same results with my previous charger. I can use the previous charger on my laptop without the battery but the new charger wont work that way. My battery can be charged by another ProBook laptop my room-mate' so the battery works.

What could be the problem? Please help,thanks in advance. Erico,The old charger the one which was repaired works but other chargers like the one i bought give the white blinking light result. Go into the Device Manager. See the following images. Right-click on any device in the device manager and select scan for hardware changes. Take a look at the charging state led.

Is it charging now and solid amber colored instead of blinking? Thanks alot Erico,bt it didnt help at all-the new charger gives a white blinking light and doesnt charge still. Does the new "charger" have the same power capacity in Watts as the original one? That is important. The two adapters have the same wattage 65 ,but I dont know if the repaired one still has this wattage-can it lose or gain wattage after repairs?
