Welcome to the wonderful world of HP and their support......none!! I have rebuilt so many of these things because they have cooked themselves well done, I can take them apart in my sleep. First, go to the HP support and drivers page, put in your model number and see if they have a BIOS update for your laptop. The new BIOS update they are putting out supposedly has a new algorithm to make the laptops fan run more efficiently and longer and faster to help keep melt downs from happening. Then I would suggest opening the laptop to expose the processor and heat-sink and purchasing and installing small square copper sheets over the processor and graphics or north-bridge chip. These can be identified by the fact that the heat-sink already has heat dissipating media on the right areas already....just replace it with the copper and then a VERY thin layer of thermal paste.

I'll give you the link to the service manual if you want to give it a shot. Good luck ParrotHead PC Repair

My compaq CQ 61-420 US notebook won't turn on It was on and we left the room for a few minutes and came back in and it was off and won't come back on the 3 lights in the bottum left flash 3 times...


Greetings! Whenever you're dealing with a laptop computer that does not power up the first thing you want to do is disconnect the AC adapter from the laptop.The next step is to remove the battery from the laptop. Then reinsert the battery and reconnect the AC adapter. Press the power switch at this point and see if the laptop will power up normally.

Laptops are also prone to overheating. If the laptop powers up after it has cooled down and then fails again you may be dealing with an overheating issue. Try taking a standard can of compressed air and blowing out the ducts that supply fair to the cooling fan, as well as blowing off any "dust bunnies" or visible debris that have accumulated on the cooling fan itself.

Also make sure that the laptop is not sitting in an orientation that impedes the airflow to the cooling fan.

Computer wont charge the light comes on every few mins for about a min then goes off i can turn it on but only stays on a few mins i have a compaq presario r3000


The lithium batteries that laptops use have a 3 year lifespan. If you have had the battery for that amount of time then you have reached the end of it's life cycle. Most manufacturers build in a warning message that will pop up to let you know that you have reached that time frame and it is time to change the battery. If your battery is not that old then you have an issue either with the battery itself or the charging system built into the laptop. The only way to identify what the problem is would be to switch out the battery to another laptop and see if it would charge properly. If you do not have any access to the same model of laptop that you are currently using then the other choice would be to take your unit into your local HP-Compaq repair center. Usually the batteries are warranted for as long as the original warranty period on your laptop. The warranty would not cover the life cycle. If age is the problem then your only recourse is to buy another battery.


Thank you for the opportunity to assist you in resolving your issue. Should you need further information or assistance please do not hesitate to let us know.

My television turns itself off after a period of time. What seems to be the problem? Thank you for your assistance in advance.


There can be several causes for this, few of which you can do anything about. However, a few things to try:

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

I hope this helps. Joe

Lexmark X5470 powers on and off constantly


I encountered the exact same problem with my Lexmark X5470. After a power failure on Aug 20, the printer would reboot itself every few seconds. I unplugged the power cord and/or adapter for a few minutes and after replugging, it worked fine. However, the problem returns after I power off the printer and then turn it back on, in which case I unplug again for a few minutes. Hope this helps.

Black, cannot boot up... etc.


Try taking out battery and plug in power. If it works, battery is faulty.
If not, try taking out your hard disk plug in power, if it works, hard disk is faulty.Try taking out memory card, if there's a sound, memory card faulty. If no sound, it's your motherboard that is causing the error.

Note: If machine is under warranty no need to pay for the repairs.
