Question about HEWLETT-PACKARD HP ProBook 6455b Notebook

Open Question

My HP Probook 6455b has a black screen on start up

I have tried to start up my laptop. It will start as in all the mechanical parts inside will run and you can feel the heat from the fan, but the screen will not light up or show any form of operating. I have tried hard reboot and attempted to reboot by means of clicking the windows button and trying to select the power off selection. Keep in mind that the screen is black at all times, so I dont know if I have even selected the correct option or even if its working at all. Please help me fix it cause I need my laptop for school.

SOURCE: Whenever I start my HP

That message means that your hard drive is bad and is not seen by your computer. If it is under warranty, HP will fix it. If not, you can find a hard drive for it for $70 +, depending on what capacity you purchase.
Although the hard drive is bad, a good tech can retreive your data, ie: documents, pictures and music from it.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

SOURCE: My HP Pavillion laptop g61 wont turn on or off.

I had trouble looking up that model on the HP page, but you should check this page and see if this model is affected by this NVidia litigation. If it is, you can get it fixed/replaced on NVidia's dime.

Good luck!

SOURCE: hp probook 4530 ac connected indicator flashing. will not power up

Either your charger is not providing the perfect voltage or there is a short circuit in your motherboard. Try replacing the charger first. If still the problem persists then you should check the connector. try resoldering it cause loose connection in it also sometimes causes this problem.or you need to change the motherboard finally.

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
