Presario Cursor Shuts down

Compaq / R 4000
January 13, 2009 at 17:09:46
Specs: Windows XP, Don't know
My Compaq Presario just "quits" after a few minutes of use. The cursor just refuses to move ( I don't use a mouse I run only the cursor pad) and at the same time the keyboard goes unresponsive. The only option is to push the power on / off switch and reboot.

If the machine is initially booting after being shut off for a few hours or more it takes a few minutes before it goes out to lunch. Everything works normally until it decides to quit.

Once it goes into quit mode all avenues of user interface are inoperable. Whatever screen was open when it quit remains displayed.

If I immediately restart it after it "takes a powder" it seems that the amount of time before it heads back to the powder room again is shorter than it is when the machine is booted from stone cold condition.

I am suspecting some sort of overheating issue but have no other related clues to this problem beyond what I have said here.

When I reboot it will run for a few minutes or less then the same thing happens

Boot to the BIOS and let it sit there for a few minutes. Does it freeze?

If the PC has 2 RAM sticks, try removing 1 of them and trying to boot again.

Thanks for the reply.

I tried to do the suggested test and proceeded as follows. I did not try the Bios boot yet but FWIW I now think even more strongly...almost certainly, that it is the FAN. I started the machine up today with it stone cold just to see how long it took for the machine to quit. Just a normal boot up changes to the normal boot sequence. It came up A-OK and took about 9 minutes before it went to lunch.

The machine has two fans under it and one does not run. I took a small piece of parper and slipped the end of the paper thru the grills and into the each of the fans. One is running, you can hear the paper flapping against the moving fan blades. The other one is doing NOTHING. The fan that does not work is on the outside of the chassis, that would be of course the underside of the machine on the right hand side of the computer as you sit facing the keyboard.

I think that the machine is OK UNTIL that fan needs to do its job, then without the fan running some component overheats and shuts down keyboard functionality and cursor movement.

I am going to let it cool off then try the suggested boot process. Once it comes up I will time the interval before it croaks...if it croaks.

Stand by.

Yeah some CPUs throttle back and shut down completely if they get too hot.

Keep us posted.

"Boot to the BIOS and let it sit there for a few minutes. Does it freeze"

Ahhh I though I knew how to do this. Guess not.....I was wrong thinking somehow of Safe Mode. Can you please advise how I "boot to BIOS"

If it does shut down / freeze when I boot to BIOS what is that telling me???? / Telling Us???? If it does not freeze what is that telling me???? / Telling Us?????

To get to the BIOS, you start repeatedly pressing F10 until a screen appears. This key varies with different PCs. Sometimes it's Delete, sometimes it's F1, F2, of F12, but for newer PCs, I find F10 is the most common.

If it freezes in the BIOS, that would indicate a hardware problem of some sort, like the fan or something else; that usually rules a software problem out.

Keep it booted to the BIOS for 15 minutes if you say the PC freezes after 9 minutes after doing a cold boot.

A dirty cpu heatsink or non-functioning cpu heatsink fan are the most likely culprits. Make sure the heatsink is clean of dust and its fan is spinning.

If it has a video card with a fan check that too.

OK !!!!!!!!!!!!!!!!!!

We are making progress. I have had it booted on the BIOS page(s)for about 1 hour now. I just left it sitting on the BIOS page. Everything stays up and running. I can move around the various BIOS pages etc. using the arrow commands and all appears well.

I must say I have not done anything with these BIOS pages in the past but IF moving around from page to page with the F Function keys is the tell tale test then I am apparently proving that there is a hardware / fan / heat sink issue.

Now can someone verify that what I hame doing / have done is the correct test to diagnose this problem?

I am guessing that I have another step to take that involves a new fan or cleaning the heat sink. Can I take the back off this thing and clean the heat sink, check the fan w/o ending up with a pile of parts that are no good to anyone????

I am VERY VERY good with mechanical things and 110 / 220 volt electrical circuits. My fear about this is just taking the darn thing apart. Never pulled a laptop apart. Some advice on this please. Is this just a work carefully with a screwdriver activity?

Last but not least. If that one fan is dead then how / where do I go about getting a new one?

Thanks to all respondents.

WHOOPS!!!!!!

I reported too soon. It has been about 2 hours since I began the test on the BIOS page. NOW IT TOO IS SHUT DOWN! No more function key movement around the BIOS page! All locked up, same as what happens on other screens pages. Only difference is the amount of time. It took more than an hour but less than 2 hours for it to lock up during this test.

Hmmmmmm?

Ok all you "Cyberspaces Benefactors" where do I go from here?

Again thanks for the help on this.

Well with the freeze occurring in the BIOS, that proves that it is a hardware problem for sure.

You said that one of the fans is not spinning. Which of the fans on the system below is it that's not spinning?

If you take the laptop apart, keep track with how things come apart. Laptops can be a bear to put back together.

I think this has something to do with the fan not spinning, but can't tell for sure. Some fans only run when needed. Did this fan used to run, and if so, did it run all the time? When did the freeze-ups start happening with this laptop?
