Was the new one that you purchased from HP? If so, then did the model numbers of the old one match the new one you bought? If the new one isn't an HP power supply, then that could be the reason why it won't charge your battery. Some of the "after market" power supplies will be enough to run the computer, but they aren't all able to charge the battery. It could also be the DC Jack on the motherboard that has gone bad. If you are not familiar with de-soldering a component from a motherboard, then you may want to think twice before attempting it. You will have to get the exact jack that goes to your motherboard, de-solder the old jack, & solder in the new one. Trust me, de-soldering and removing an old jack isn't always as easy as it sounds. You will have to completely disassemble your laptop to do that too, so be sure to keep track of all the little screws and which screws go where.

My power cord seems to not be working with this computer. I have tried all the outlets in my house and nothing is charging my laptot.


I'd call HP and request a new power adapter. I've had a few of them go bad before and it's just a short in the cord. Your plug might be loose also...but a good place to start is by calling HP and getting a new cord.

Was a new or a refurbished hard drive was purchased? If new Replace the power supply instead. The power supply can cause hard drive failures even on new hard drives. Never purchase a refurbished hard drive neither

Why wont the mouse,keyboard and monitor not work after cpu,pwer supply install...


If the motherboard used to work with the old cpu and power supply, but does not with the new cpu and power supply, then probably the cpu or power supply is bad.
Why did you change the cpu and power supply?
If the power supply went bad, it could have overloaded the mother board as well as the old cpu.
If you think the old cpu went bad, how do you know it was not actually the motherboard that went bad?
All I can suggest is that you double check all the connections.
If you have USB mouse and keyboard, try a DIN connected pair.
If you are using the onboard graphics, try a PCI express card instead.
Tell us if there is any front light activity from the power switch, drive, etc.?

Hp Pavilion 763n won't startup light on fan on cpu not running


The most common issue is a portion of the power supply has gone bad (power supplies provide +5, +12, -5, and -12 vdc). Otherwise, the motherboard may need replacing. Try finding a spare power supply from a friend and hook it up to see if everything runs fine before purchasing one (about $40-50). If the power supply doesn't fix it, it could be the CPU (although I believe the CPU fan would still run) or any portion of the motherboard.

My computer won't turn on! It seems like no power is getting to it, even though it is plugged in and SHOULD be working fine. Please help!


check if your power used to connect form your CPU to the outlet is not defective...use a multitester to test the said cable,,or simply use another power cord and conenct it from your cpu to the outlet...if still the same you have to purchase a new power supply since there is no power and your curretn power supply is already defective.

This is a motherboard problem. You'll need to replace it. Although, it may be cheaper just to buy a new PC (eMachines are never very expensive, or well-made for that matter)

I agree...sounds like a power supply problem. Typically a bad power supply will not damage the motherboard. It should still be functional.

HELP! No video on Sony Vaio VGC-RA710G desktop


Since the power supply wasn't secured properly it actually contacted the motherboard while it was still carrying a charge. For next time, I use zap straps for all of my wires and to secure components. Try removing the motherboard and doing the power supply self test, most likely you will have to replace both the motherboard and CPU though.

Replacement Battery


PDA 2005 (as old as)
bad power supply ( weak)
bad battery charger chip inside.
this device has no value, really, why spend hard labor on such old tech? if compelled, buy 2 or 3 other dead 4360s ones, used off fleabay
to get one good one.
There is no PC made that will not fail.
consider this, if you had 2005 Toyoto car and the alternator went
bad , as all do about NOW. do you Boycott, Toyota.
nothing made by man lasts.
even earth is doomed, but not in 11 years.
