The power supply is the issue, or the DC jack in the laptop has developed bad connections, or ram issue. Remove 1 stick of ram and power on, if no! remove second one, and replace the first, power up, if no! test the power supply for proper voltage, if okay! it is a DC jack or motherboard problem.

Hp probook 6455b will not turn on why?


Take everything out of it that you can. That would mean the ram and drives, see if it boots. IF it does, then put the ram back and check it again. If it does put the hard drive back etc. If you get to the point that it wont boot with nothing installed then it could be a dead cmos battery or a loose CPU or something like that or a bad mother board.

No power on HP ProBook 6455B


Hi there,

Try removing the charger and the battery, then replacing the changer while the battery is out. This does a hardware reset that can sometimes solve issues like yours. If that doesn't work, you could be correct in assuming it's the button. If you're brave you can check the connection of the button to the mainboard. In this video: http://www.youtube.com/watch?v=Am6na_9HDww at 5:24, you can see the ribbon cable just above the keyboard connection, re-seating this may also solve your issue.

Thanks,

Liam

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen
