Due to a problem with my previous CPU, some pins broke while I was cleaning the laptop out, I had to get a new one. The original CPU is a P4 2.8GHz 533Mhz FSB SL725. I looked on ebay and found many results but also found a P4 3.0GHz 533MHz FSB SL726. After looking up some information on my laptop I found that the chipset supported the SL726 as well as the SL725. I then figured that I could use the little upgrade and bought it. After receiving it, plugging it in, adding some thermal grease and replacing the heatsink I turned it on.
It got to my boot manager and then all the lights on the front went out and even the light on the power supply, an external 3rd party model, turned off. After about 15 minutes of use it then shutdown due to low batter, yes I am aware that I need a new one. I found that after unplugging everything I could try again but with the same exact result, except in about 15 seconds due to the now discharged battery.
The question is really two. First, could the extra power requirement of the faster CPU, about 7 Watts as I recall from the spec sheets, be causing the internal power circuitry to fail and cut all power causing a shutdown? Two, could the BIOS have a setting that only allows the SL725 CPU and no others?
Answers are welcome for both and as always thanks in advanced.
Also, because of the date I would like to wish a Merry Christmas to all who may read this.

I'd love to hear the details of how you ripped the pins off your CPU...lol.

How much thermal paste did you use? For a desktop CPU, the recommended amount is a small dab about the size of a BB or grain of rice. I'm not sure of the recommendation for mobile CPUs but I assume it's the same.

Did you break the pins in the socket? Did you force the CPU in? Does the laptop make a noise of the monitor show any warning messages etc? And "Jam"

I think we all "lol" at him now but we all have done it before :(

OK jam, here are the details. Because of the design of my laptop, you have to first release the CPU from the ZIF, then lift the entire heat sink assembly with the CPU attached to it. This makes it difficult at best to reinsert the CPU back into the ZIF which caused some pins to be bent and straightened over time. Well two of them decided not to play along anymore so they crapped out and broke off during the straighting process.
As far as thermal grease is concerned, I used enough to see some extra kind of squirting out on each side, which I cleaned up, after tightening down the heat sink retainer.

Now onto 02coled's questions. None of the pins broke in the socket and the CPU was not forced in, it dropped in quite easily as it should. Also my laptop is showing the normal POST screen and not making any weird noises.

The issue here is with the laptop shutting off the external power supply and then shutting down when the battery out of juice, like I explained in my original post.

"As far as thermal grease is concerned, I used enough to see some extra kind of squirting out on each side"

If that's the case, you used WAY too much paste & THAT is most likely the cause of your problem. Pick your CPU from this group, then read the instructions:

Thanks for the link but I followed those instructions, my CPU is single core with a heat spreader, and it won't hurt it to have a bit showing on each side.

In other news the problem has seemed to solve itself. I have been able to leave the computer on overnight now without the power supply shutting down on me. I didn't do anything to it, it just seems to have worked out the problem on its own.
If anybody knows why this problem occurred in the first place than I would like to know as well. But if not than that is OK too.

"and it won't hurt it to have a bit showing on each side"

If it's oozing out on each side, you apparently used more paste than the recommended "grain of rice" sized dab
