Question about HP Pavilion ze4400 Notebook

1 Answer

Absolutely no start up. Power button does not work at all. (HP)

I received an HP Pavilion ze4400 for my 16th Birthday (about two months ago). Everything was working fine until it started to overheat and power off, no problem. I bought a cooling fan, and the issue was solved -- Until early yesterday (July 10th) morning. It had overheated (after about 10 hours of NO use) and shut down. I waited for it to cool off before coming back. When I pressed the power button nothing happened. It doesn't start up, at all. NOTHING happens, not one single thing. I've been told by websites that my motherboard is shot. After only two months of use I hope this isn't true. PLEASE HELP!

    Also, this computer was given to me by my dad. I'm sure he bought it off Craig's List,(he had it a bit before me, and his brother [a computer wiz]replaced the motherboard before I got it), so no luck in returning it to the store.

    Yes, not even that works.

    I'm not sure what video you're referring to. The laptop won't even turn on, let alone play video...

    I'm slightly confused.

With the motherboard constantly overheating that is a sign that the motherboard is bad because that means its not regulating the voltage properly and too much is going thru which is why it gets hot even though the fan is working.

There are some steps you can take to verify this though.

Only plug up your ac adapter and leave your battery unhooked and see if you get video that way.

If you don't then unseat and reseat the memory one stick at a time in each slot one at a time and turn on the laptop after each stick reinsertion. If you have an extra stick of known good memory then you can try it in each slot to see if you get video. You want to make sure its not a memory or memory slot issue.

If you don't get video this way either then go ahead and remove the dvd drive and then the hard drive.

If you still don't get video then you know for sure that the motherboard is shot and it would need to be replaced to fix the problem.

My HP Pavilion PC will not start. The on button indicates it is on but it is not. Monitor says "no signal". The power supply failed a few years ago and it was replaced. Do you think this is what happened...

I do not know exactly what is going on with your computer, but if the light by the power button comes on and stays on then you can try pulling the ram out of it and then put it back in. A few years ago i had a compaq computer and all of a sudden it would not come on but the light by the power button was on. I thought the computer was shot but i contacted a tech and he told me to pull the ram out and put it back in. I did this and the computer came back to life and worked fine. Good luck. I hope this works for you.

I bought HP Pavilion dv5 6 months ago and fan not working

Your cooling fan sounds to have went out,causing it to overheat and shut down.It also could be something in the fan stopping it from turning.Try cleaning it or blowing it out with it off.But it mostly sounds to have went out.

My hp ze4300 will not turn on

Has there been a power surge meanwhile? If so, try unplugging the power cord, press the power button, reconnect power and try booting. Sometimes works.
