The only thing I can think of that would do that is if the power setting are messed up. There are different levels of power settings you can choose. Normally on the battery it runs the CPU slower, the screen less bright and so on to save power and make the battery last. It almost sounds like the full power mode or the adaptor mode is using the battery or extended power settings.

What you can do is look under control panel for the power settings icon or right click on the battery or the power plug by the clock and then adjust properties. Look for the tab or pull down that says A/C power or Full power or something like that. Then you need to go to the settings section for the cpu and cooling. Those are the two that have to be adjusted together. Depending on the software controlling you will either see a min/max setting or something that says cpu speed. Just adjust the max to 100% or set the cpu to variable. You can set it to max but that runs fast all the time and is noisier than it needs to be as the fans will always be running harder. And double check that the cooling settings are set to variable as well. Once you save or apply the settings your laptop should be much faster. There is a chance there is a setting in the system bios that is set to slow cpu but that is supposed to be over ridden by the windows software.

Anyway thats about the only thing that I can think of that would do this.Once you get the speed sorted out you can use the same panel to tweak the battery portion to run slower and not use as much power. If the cpu is allowed to speed up and down it only uses more power when you run more so it can slow down when its not needed. Think of this just like a car going up and down a hill. Power to go up then coasts down.

Hi why does my hp nc6220 screen flicker like a beacon when booting has finished so much that i can barely view the desktop


You may have a problem with the display driver. I would go to the Control Panel>System>Device Manager and delete the display adapter and then reboot. It will automatically re-install the default driver when you reboot. If that doesn't help, go to the HP website and download the latest driver from there.

HP Compaq NC6220 No Power


Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

When I hit the power on button on my compaq nc6220 the yellow battery light flashes and nothing happens


Please try removing the battery, and then connect the power adaptor and try switching the laptop on see it if works if it works then the battery needs to be replaced. I would also recommend if you can check your power adaptor / swap your power adaptor with a know good adaptor (if you have one). The remaining steps will depend on the outcome of the steps above.

Hi. My son's hp compac nc6220 has a problem. When one checks for the 18.5 volts at the power supply plug all is well but when i plug it in the voltage at the motherboard side drops indicating that there...


The power adapter could be faulty and not the Compaq.
Try putting a small load resistor on the power plug on the adapter and measure the voltage.
OR
Try another power adapter and connect it to the Compaq

NC 6220 will not power up, power source good?


Take out the battery and just use the ac adapter and see if you get power. If you dont then if you can try to use another known working ac adapter.

If that still doesn't do it then take out the hard drive and the dvd drive.

If you still can't get power at this point then the motherboard is bad.
