HP Probook 4340s not turning on

[Gonzaga]

My ProBook wont turn on when i press the power button. When I plug in power, the LED light for charging in on but nothing happens when i press the power button. 

I have tried with a different battery, different charger, but all the same. 

I have removed the battery and memory and pressed the power button for over a minute but it didnt solve the problem. I have not hard any issues with this machine before, so am wondering how can it stop just like that!!! I last used it yesterday and it was all fine.

Kindly help.

Thanks

Hi,


No life at all while you press that Power button?

Is it the same when you remove battery and plug in AC power, try powering on?

Kindly do a hard reset and try again with AC power alone:

Hi Visruth, Nothing happens at all. I have done the hard reset as in the video but no change. The LED light for the battery is a solid orange as it should be for a working computer. 

Can i try removing the cmos battery and put it back?

Hi,


Manual: first one - Page 67

You could try that once. But it needs major disassembly to reach RTC battery.

If that doesn't work, board issue is what I would suspect. Get it checked by certified technician.
