Hp media center conputer wont turn on. button on front blinks blue to yellow and back, fan starts for 1 second, then dead. How can I check the power supply

1. Put it in another pc.
2. Check the voltages etc with a mutimeter, not an easy job and I can't tell you how.
3. Open it up (carefully) and see if you can see anything wrong like bulging/leaking capacitors, burnt bits.

Personally I'd find another pc to test it and/or open it up. If it is the psu then it's quite likely that it's blown capacitors.
Quite a cheap fix, if you do it yourself anyway (never paid anyone to fix em myself).

Plenty of info on replacing cap on this site and here's a link that covers everything, read it before you try
opening it or changing any caps

Bad caps

Could also be a motherboard or processor issue, and i'd say that is more likely, but the psu could be at fault..

I have a Compaq Presario F700 and when I try to turn it on, the power light comes on for a second (I hear the fan), but then shuts off again. The cause is most likely that I was restarting my computer for...

Test or replace your PSU power supply unit preferably with a heavy duty one with plenty of wattage remembering that with any added hardware your computer will use more power/wattage eg:more RAM ,bigger hard drive,slave drive

One bad/faulty lead can cause a computer with lots of problems continually rebooting or failing to detect your drive

replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA the ones that attach from your motherboard to hard drive

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?

hope this helps?

Hi!! Usually HP or Compaq Pavilion Presario passwords are storedin eeprom memories that has to be read or writen to remove / bypass the BIOS password!!!

Compaq Presario F700 wont turn . The blue power light next to power is a fast blink.

Well I have the same computer (I wish i didn't) but it goes threw a lot of problems I will list some solutions and hope fully it will work.

1st try tapping f8 repeatedly

2nd try taking out the battery and holding the power button for about 60 seconds then keep the battery out and plug the power in and try to power it on if that doesn't work do the same but leave the plug out and put the battery in and turn it on

3rd reset the RAM buy taking it out and then putting it back in be careful when doing this you might want to wear rubber gloves

4th try putting in a recovery dvd and turn it on if this works and the recovery starts you dont have to restore your computer just turn it off and take the dvd out and turn it on the computer

5th this might not work for everyone but it does some times work for me turn it on and if the lights turn on and stay on press every key on the key board like 11 times or more it takes forever but it has worked for me 3 times

6th well this might sound stupid just press a bunch of buttons kind of mess around maybe you will get lucky

hopefully this will help

Can't turn on PC, Presario SR2163WM

You sound like you know what you're doing, so I expect you've made all the motherboard connections(Same as the original PS). Does the switch work when you test it? If so, it sounds like the PS is DOA. I've had bad luck with cheap power supplies.
