Having problems with your HP Compaq nx9420 Notebook ?
Will not boot. Turns off after 5 seconds
\015 Problem: AFter 5 seconds, unit turns off. Will not boot.What has changed: * new battery, new power supply (which turns out doesn't have enough juice for this unit, but it was sold as "able to work for this unit" Not enough voltage (18.5). Needs 19.5 at least. Been using combination for about 2-1/2 weeks.What I have tried: Removing HD, battery, and reinstalling. Attempting to start unit with "undersized power supply", separate from battery and battery alone.Diagnostic tests were done with the Wifi, clock battery. Memory module was removed. to test feasibility of motherboard is my last action. Ran an eraser across the "gold part" of the module.As a result of removal of the memory module, I expected to hear a series of beeps to tell me the mobo and/or cpu were still functional. I did not get that sound, and wondered with the testing I have done so far, has clarified that I have a dead laptop or if there is hope still.Currently: I still have the same issue, even with the memory out and the keyboard detatched. * Other things I could do (in order to further the testing) [both will take days and cost money] - get a new power supply that is supported by this unit (the last one does not count). I do not have a "good power supply" I would hvae to buy it online. ---replace the RAM, though I am not sure if that is the issue or notAnything else I'm missing? What I'd really like to know is if I should stop wasting my time with a dead laptop, and try and find out why it failed in the first place (power supply or not)thanks for any help you can provide.\015
I would check your memory sticks i had the same problem and it was my ram.they get full and ware out
