HP Pavilion power up

I have a HP Pavilion 533c. A few months ago while the pc was on for a couple of hours, it would just shut down. The indicator light would change to yellow. I would be able to boot it back up with no problem. The problem continued to happen, but the time kept getting shorter, and now it won't come on at all. The monitor doesn't even come out of stand by. When I turn it on the fans will spin for about 2 sec then stop and the indicator light stays yellow. I put in a new power supply, but still get the same results. Could the CMOS battery be causing the problem?

    colliewob, thanks, but I'm not sure I understand what you are referring to when you say to remove all plates from underneath. The HP Pavilion is a desktop machine not a laptop.

You could have overheating problem
remove all plates from underneath that allows access to internals and blow out using a can of compressed air (from Radio Shack shop or similar) and ensure fan vent is clean and clear. then try it with all plates off if OK replace plates and try again. If still shuts down laptop requires stripping completely to clean

    On the underneath of laptop are numerous plates held in by phillips screws that allow access to memory / hard drive etc remove as many as you can and blow out using canned air
    Mine has 3 such plates give it a try even if you only take them off and try rebooting with them off if it runs OK you know its a overheating problem

Won't turn on


Susan,
Dealing with overseas tech support people can be frustrating. If the laptop is only a few days old, you really need to contact them first.

Im sure its still covered under warranty, so start there first.
If it wont boot, it could be a number of things.
If you get no where with them, please post back and someone here will try to help.

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.

Laptop turns off when charger is plugged in !!


Charger is bad and is not putting out the correct voltage which causes the computer to shut down. Battery probably isn't much good either if it only lasts for one hour. Get new batter and charger. Ebay'ers will help you find one cheap.

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.
