Solve : HP Will not Start,? |
|
Answer» HP Pavilion a6742p Windows vista Friend computer would not turn on.... everything indicated bad Power supply. When you attempted to turn it on, there was no light on the power switch/button, no sound of any kind from inside No fans turn on, nothing. Looking at the indicator light on back of the power supply it was blinking, Per HP trouble shooting guild, this iis a indication of bad Power supply. Replace the power supply, It will power on...light on in power swicth, fans will run... and so on But it will not start the boot cycle... BTW the replcaement ps has more wattage... What i have done up to this point. I have removed the CMOS battery left it out for hmmm 5 minutes press the power button and held it for 30 seconds or more while the puter was unplugged and battery out and attempted to boot again... The only thing that it will do is turn the fan on.... What I have advise her to do is Replace the CMOS Battery, and just in case.... try a differnt monitor... At this point I trying to decide MB or HD? One of the things you should have done is remove all drives and all USB devices and see if it starts up into the BIOS. A bad drive, really bad, can stop the system cold. And stop it warm too. Both HDD and DVD. EDIT: When I said 'remove', I meant disable by removing the cables, power and data.I FORGOT to mention... power button will not shut it down, could be because it not booting... I will try to DISCONNECT all cable from drives and reconnect one at a time. process of elimination. With the hard drive disconnected.... will it boot to the splash screen? (not the windows screen)****UPDATE*** Disconnected all internal drives, and everything outside except for the monitor, Attempted to boot, NOTHING no display of anytype, I thinking MB?

Lights on keyboard should flash on, then off. Should get beep from speaker. If not, might be MB.No beeps, CPU fan does come on, Remove all ram, attempted to boot with drives unplugged and connected. lights on KB did flash, no beeps, heard Cpu fan running.... ? |
