my laptop keep shuting off on its own after 20-30min and the batery is full charged what can I do?

Your laptop is probably going into hibernation or sleep mode. You need to go into where you choose the screen saver and things like that and make sure that these options (hibernate and sleep) are turned to 'never'. Good luck

just leave it on.\n\nthat's my answer.  but you do have to edit your power preferences so your computer doesn't turn off after 2 hours of non use.  other than that, I don't know.

I'll try to return the favor of answering your q...\n\nI have a couple of decades of hardware experience, and your problem is one of the more difficult to pin down quickly. It's possible you have power supply problems (your electrical system). If the voltage dips "too far" (how far is too far depends on the electrical device) then your Compaq may shut down. Different computers, even different Compaqs, may shut down more, or less easily as the voltage coming from your wall outlet sags below 120 volts. You may, or may not, notice the lights dimming, but it may still be enough to trip the off circuit in your Compaq. If you don't have one yet, spend $40+ and get a battery backup (UPS). It'll help any system last longer, too. I like the APC UPSs.\n\nSecond possibility is that your Compaqs power supply (internal silver box) may be getting flakey. I haven't worked on a Compaq in a long time, but they used to have "custom" (proprietary) power supplies that required going back to them (Compaq) for a replacement (at a premium price). If it's a standard size/shape, then a new power supply is only around $50 to $60 and available at most local PC stores. Not a lot of expense, and easy to replace for even a novice. (Please uplug the system from the wall first, and try not to touch any electronic components inside the computer during your foray into the inner-world of your Compaq.)\n\nIf you still have trouble after confirming your electrical supply is good and your power supply isn't causing the shutdown, it is -slightly- possible you have a bad hard drive or mainboard. Replacing either of these is doable, but not for the non-tech. If you have a spare hard drive, you can just install it (replace your current hard drive) and fire the system up...let it sit...if it runs for a substantial amount of time longer than it usually does, then you -might- have found the problem. \n\nFinally, you may just have a heat problem. Try making sure all the vents (front, side, back) are clean and clear of obstruction. If you feel competent, take the case cover off and blow out the dust inside (but take the system OUTside first!). I've seen systems in relatively clean office environments build up a half-inch of grey fuzzy 'lint' all over the inside in less than a year. Even if this doesn't fix your problem, it'll probably make your system last longer by running cooler. I've seen hard drives that ran as low as 90 degrees F, and as high as 175 degrees F. The lower the better...within reason (less than 120F should be fine).\n\nHope this helps.

Even though the battery says its charged it may be bad. Do you know someone with the same laptop, so you can borrow thier batttery to test it.

I would call dell tech support up and let them know the battery is a dud.  To keep the battery lasting longer fully charge it then let it drain 2 or 3 times right off the bat then fully change it and drain it once a week do not leave the power cord in the computer when you don't need it.  If you do this constently it will kill the battery.

If you have already checked the battery, what about the AC adapter cna you run it just on the mains, does it shut down. \n\nIf it doesnt shut down, it just may be that the battery is faulty  or even check the power save/optimisation settings.\n\nIf it does shut down then check the following:\n\nLaptop overheating - make sure none of the vents are blocked/clogged up, when in use.\n\nProcessor Overheating - CPU fan may be faulty, so processor starts to overheat and system shuts down to protect the processor.\n\nGet it checked out by a pro, to be safe.\n\nGood Luck\nBattery Wizard

If your power supply is faulty or your processor fan is broke your PC will shut down to cool down, but wouldn't necessarily start up again.\nIt sounds like a virus or worm infection.  I would try going into windows in safe mode (F8 function key normally) and see if the system continues to close down.\nIf it is stays on o.k. check you haven't installed a driver or software recently that may be conflicting with Windows.  If this happens you should be able to roll back the driver or system restore to a point where you know your PC was o.k. (In F8 this is the "Last known good configuration")\nIf it shuts down again it may be a virus, have a look on symantec's site for a hotfix for the latest virus/worm,if it is a virus you'll proably need to disable your system restore whilst trying to remove it.  Follow the instructions to remove it carefully so not to destroy your pc further!!

That is a pretty old laptop.  I suspect the battery may be so old it may never charge and you will have to get a new one.  One option though is to put the battery in the freezer for a few hours and then give it a couple of days to charge up.  Some times this can revive an old battery for awhile longer.

How old is your laptop may I ask? Mine has done that a couple times after it comes out of stand-by, but it eventually turns on. Your hard drive isn't starting up, or there isn't any power getting to the hard drive.

check the power cord to see if there is a break if not then it most likely dead try and take it to computer shop and see what they say you can get a new one if they say it dead

Your computer shutting itself off can be a symptop of 4 things.\n1. Windows power saving settings. This is unlikely to be the problem if you are using the machine.\n2. You're on a laptop that has run out of battery life. Trying using only your power adapter.\n3. You may have a defective motherboard, processor, memory RAM, video card, or powersupply. My suggestion is to always start with the cheapest to the most expensive. I'd try replacing your Power Supply with one of quality with sufficient wattage(not the cheapest power supply you can find). I have found that AMDs are more sensative to power flucutations as when CD-ROM drives and Harddrives spin.\n4. The mostly like possiblity is overheating. As mentioned on here, most new motherboards have a temperature threashold that will automatically shutdown your PC if it gets too hot. I suggest making sure you have sufficient air circulation (cool air coming in from the front, passing over your motherboard, and out through the rear exaust). You should have a quality heatsink attached with thermal paste (helps avoid heat pockets being trapped between the processor and heat sink). On the heatsink you should have a fan that is clean of dust and rotating at its proper top spead. \n\nAnything else is just random and rare cases.

On a laptop, it shouldn't affect the computer, provided your battery is in good working order.  If your laptop's power supply failed, your batteries should kick in until AC power is restored.  If you think it's your power supply, try to get another one to see if it happens with that one.  If that's not the case, then it may be an internal issue (overheating, for example).\n\nOn a desktop, though, the power supply might be a cause, but then again, viruses, a bad motherboard, or overheating could also be causing your computer to reboot spontaneously.  You'd have to take more notes when it happens - does it happen when you do a particular thing (maybe a virus) or after a certain period of time (maybe a virus or a heating issue), or is it completely random (power supply may be working intermittently)?  And then, after your computer shuts down, does it come back up immediately or does it take a few minutes to start again (maybe a heating issue)?  I would check for viruses first before getting into the case.  If I went into the case, get some compressed air and blow out all the dust, and then see if all your fans are working properly.  And if that doesn't help, try another power supply if you can.

my brother's gateway has the same problem...after a while pc batteries run out of power...you drain a battery by using the laptop not plugged in until the computer goes to sleep because it has no power...

It's either your power cable/power adapter, a bad power connector on the motherboard, or a bad CPU/CPU fan. I had a dell inspiron something or another and my power connector on my motherboard broke so it would not turn on unless I had it a certain way but as soon as I moved it or bumped it, it would shut back off. If it doesn't power on, I'd say get rid of the Dell and go with something more reliable like HP, Toshiba, or Sony (just to name a few) Look on ebay or tigerdirect, or hp/gateway/etc for used laptops.  Good luck with fixing the hunk of junk from Dell.

not sure\nthe best - unplug and re-plug ur pc, then restart..

Goto your CONTROL PANEL and select POWER OPTIONS.  Make sure it is set at a level you want, I assume it says to turn off hard disk after 20 mins...Just change that to NEVER.

This is normal, if you have not used the computer for a pre-set time. If that is not the case, check the battery.  Try another one if available.  If the problem is not the battery, then you may need to check the setting of AMP/ACPI in either CMOS or Power Options in the Control Panel.  To access CMOS, you press F2 or F3 or F11, or one such keys: as the computer starts up (watch the screen carefully during startup)and it will tell you which key  to press to enter CMOS. Go to Power Management and look for ACPI.  Set it to "Off" .  Then restart the computer.  If you still want it to turn itself off after, say, 30 minutes, go to "Control Panel" after the desktop is available, choose "Power Options", and the computer will lead you throuh the rest. The last settings over-ride CMOS.
