I have a Presario R3000 running just on the power supply with no battery yet. And have cleaned dust and stuff from the ports and took the cover off to clean the fans as well a few months back. Just recently I took the fan cover off to watch the fans when i turn the laptop on and both fans come on at first then after a few minutes one of the fans stop. Could my fans need replaced are they getting worn out and going too slow? I recently installed Speed Fan and it shows my CPU diode, Temp2, Temp3, Temp4, Temp5, Temp6 and Temp7 at 102C or 216F. The HD0 is 35C or 95F and Temp1 is 54C or 129F, I noticed before my laptop shut off a few mins ago the Temp1 reading was around 99F or 37C. Also for some reason where it says Fan1 and Fan2 they both say 0 RPM, but as i type this i can feel with my hand on the back port that The Temperature on my taskbar next to the clock shows 199F or 102C. My laptop is running Windows XP service pack 2, Intel Pentium 4 processor, 3.00GHz Dual Core or Hyperthreading I'm not sure, and 448 MB or RAM, i have the laptop sitting on 4 hairspray type lids so its sitting about an inch and a half off the table, it helps a little sometimes.

The way to find out your current BIOS is given on the linked site. Just press F10 when the Compaq logo appears. Try entering it on the site search engine, (and/or go through the lengthy product and model ID procedures) to see if there has been an update. If that doesn't get you anywhere, then e-mail the support staff about the problem, and ask them if your BIOS is the most recent version for your PC. They might be able to offer you some other suggestions if that isn't the cause of the problem. Hope this helps.

hi,

102C is high and would surely cause a shut OFF. have you opened the laptop up and clean the insides? if you have not done so yet, reapply thermal compound. if doing so shows no improvement, try replacing the fan.
I've cleaned dust off the fans and cleaned dust off the heatsink, I just ordered some Arctic Silver 5, i'm just waiting for it to get here so i can apply it to the processor to see if that helps. I've watched the fans before and they both come on when i turn the power on. One fan runs constantly and the other fan is suppost to come on for a short while when the cpu gets hot and cool it off right? Well i don't think it kicks on, so does that mean it's bad? Or is there a problem somewhere else? If replacing that fan doesn't work, would it be possible for me to splice the wires and connect both fans together so they are both running constantly? Or would this cause a short or voltage problem?

I updated the BIOS, but i read on the website that the update just deals with a battery charging problem.

Well i don't think it kicks on, so does that mean it's bad? -- test the fan if it runs, you can do this externally, remove it and use a battery. if it spins, then it is still good. that leaves you with the motherboard that controls the fan. btw you have to figure out a way to wire the fan to a battery.

Or is there a problem somewhere else? If replacing that fan doesn't work, would it be possible for me to splice the wires and connect both fans together so they are both running constantly? -- this is possible but i do not think it is a good idea.

Or would this cause a short or voltage problem? -- it could if not done correctly.

Well I got the arctic silver 5 in, applied it and didn't seem like it made much of a difference. Although, I put a napkin on the side fan port and noticed the side fan is kicking on, but only for about 2 to 3 seconds or so, then goes off, and the air coming out is very hot! My laptop is still shutting off, I don't know if i mentioned it or if it makes a difference, but i'm only running on the power supply, no battery. Shouldn't make a difference though, i would think... I have a new 12 cell battery on the way though. This might be a stupid question but, the oily substance i saw when i first took my laptop apart on the heatsink and fans, i was wondering if you know what the R3000 heatsink looks like... if there is some kind of liquid inside the tubes running to the cooling fins? Could it have leaked out if there is fluid in there? I doubt there is but i could be wrong? Could this be where the oil came from and why its still overheating? Or maybe a previous owner spilled something on it, or might have sprayed some WD40 or 3-in-1 oil on the fans if they were rattling... i just read about some people with a rattlin fan problem. Hmm, I dunno what else to do, my fans are coming on, so I guess they are still good?

Forgot to mention, the side fan that kicks on when it gets hot, isn't loud at all, you can barely notice it. I don't even think i could hear it, the only way i could tell it was on is when it was blowing on a napkin i placed near the fan port and then i placed my hand there. Could my fans be getting worn out and going slower than they should be, or no? I think when i first got the computer the fan kicked on more often, because i always remember feeling how hot the table was next to that fan port. And also its a wooden table so me and my friends sometimes could smell what was like wood burning and couldn't figure out what it was for a while, and then noticed how hot the table was. So thats what got me thinking that fan doesn't seem like its kicking on as often or as fast as it should be...?

The tubes you see running from the heatsink to the fan area contain no liquid. They are called "heat pipes" and serve to conduct heat away from the cpu area over to the fans so it can be dissipated.
