My compaq laptop shuts down All power connected and battery shows good. It runs for 3-5 minutes and then shuts down.. Almost like overheating or something like that and something shuts it down.

CQ60-615DX shutdown do follow step:
1) as a new laotop with windows 8 return to windoes 7 need to update a proper BIOS version to get good campatible current system

2) the Battery should be good, the charging issue is also link to BIOS version support, or check dc jack LED indicator on when adapter plug in. not lights no charging
3) check adapter plug in DC jack lights, shutdown could be related to if the lights not on. may be try change adapter first
3)

Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard

This could be a motherboard issue. Make sure the screen isn't just shutting off after 15-30 minutes. If you hear no fans or anything else running, I would say do a laptop craft project. They are very enjoyable!

Here's what you can try.
1. Remove the battery and try turning the laptop just from AC adapter. Maybe the battery is bad and shorting the system.
2. Try turning it on just on battery power (with AC adapter removed). Maybe the AC adapter is bad and shorting the system.
3. Try removing memory modules one by one. Maybe your failure somehow related to memory. Test the laptop with only one memory module installed. Try either one.
If nothing helps, the laptop still turns on and off by itself, most likely this is motherboard related failure.

The most common problem you get with a laptop is overheating, this can cause for it to shut down while operating to prevent more damage.

You will know if your laptop is overheating if it happens one ore more of the following:
-The keyboard and the bottom of your laptop are very hot when the laptop is working.
-The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
-The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
-The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).
Follow this steps to avoid overheating:
-Don't use your laptop in full sunlight for extended periods
-Don't leave the laptop in a closed car on a sunny day
-Don't place the laptop on or near extreme heat sources, such as radiators, hot air vents
-Turn off your laptop before putting it in your carry bag
-Turn off your laptop when not in use for a long period
-Work on an even surface as much as possible, not on your lap!
-Clean the air vents in your laptop regularly by using a can of compressed air
-Get more space under your computer by propping it up on something when it's on a desk
-Consider purchasing a laptop cooling pad
-Consider purchasing an external fan

To clean your laptop's cooling system:
-Shut down the laptop ie do not leave it suspended, sleeping or hibernating.
-Unplug all cables from the unit and remove the battery pack
-Get a can of compressed air and blow it into all vents around your computer - this should clear out any dust and hair.
-Do Not use a vacuum cleaner.

If it is not overheating, then it is a hardware failure. Could be the RAM memory, or the motherboard. You can only corner the problem by testing with different RAM modules or motherboard.

Hi..

If the laptop shutdown maybe it cause overheating.
Laptop shuts down? Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage. If the smart person keeps turning the notebook back on and figures out a way to foil the protection, the laptop is probably doomed. Once a laptop shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot. The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated laptop is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down. Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning.

Good luck !!!

It is possible that the battery is not charging at all and can't pass electricity to the board. But if its 3yo, its probably really dead.

Also, if you can see a fan not working at all, overheating is also possible.

It is also possible that there is a tiny foreign object capable of conducting electricity, such as human hair, that gets activated at the slightest movement of the laptop by shorting some pins on your board.

So I would suggest to observe more or clean the inside of your laptop if you know how to remove your keyboard.

very first thing u have do is if u have any other laptop try and connect the aac adaptor with that laptop and also try the battery if it is working with the other laptop that means the motherboard of the computer has gone bad u need to replace it and what also u can try is disconnect the ac adaptor and take out the battery from the laptop and the without ac adaptor and the battery press and hold down the power button for one minute and then connect the ac adaptor and put the battery back in and then try and turn on the computer and also what u can do is shut down the computer first and then just hit the power butoon once only to turn it on and then keep tapping f8 key on the keyboard and it will take u to windows advance options and select safe mode with networking and then try if it turns on to the windows screen or not......and if it doesnt turn ono then definately replace the motherboard...good luck....

Hi Asadi Hope you doing good. Please try the following solution : 1. Disconnect the power cable. 2. Take out the battery 3. Keep holding down the power button for 60 seconds. 4. Put the battery back in. 5. Connect the power adapter 6. Make sure the Power adapter is switched on and laptop is on AC Power 7. Wait for 5 minutes and try to restart the computer 8. If it still doesn't starts. 9. Hold down the power button for 60 seconds with AC adapter and battery connected 10. Try to restart now and check. 11. If it still doesn't switch on 12. Take out the battery and run on only Ac adapter and restart. Please advise if this still doesn't helps. Regards Harry
