Powering On And Off

by patrick121 / February 27, 2004 11:55 PM PST

Hello,

I have a Compaq Presario 2100 series with Windows XP installed on it.. i'm not sure if this is the right place to post this but i'll ask it anyway;

My computer will power on for about 3 seconds and then power back off.. and then repeat this pattern until you take out the power cord from the back..

Any ideas on what could be wrong?

Re:Powering On And Off, but is it broken?

It's unclear if its broken or not. Some machines do that on shutdown and a review of the XP Shutdown Article two clicks from http://www.aumha.org/articles.htm would be helpful. But if it never boots, then disregard that and tell if its broken.

If under warranty, call it in.

If not, cry a little and try this. Unplug and remove any part you can. Reassemble and try again...

powers on then powers off...repeatedly

I had the same problem with my 3 yr old HP Pavilion desktop. After putting it into sleep mode I could not wake it up. After powering it own manually it would not start up properly. It began to power up, but after about 4 seconds shut down. Then began to power up, then doff. It repeated this over and over. I tried to remove the power cord, all USB inputs, the keyboard, monitor, etc. Nothing helped. I opened it, cleaned the fans(which needed it) but still no luck. Finally, I replaced the lithium back up battery for the BIOS (CR 2032, in my case)and voila, that was it. I had to reset the date and time, but other than that everything was back. Hope this helps.
