Hi guys
I have a really strange power issue and cannot loaclize the problem and i was hoping that someone could assist.

I have a HP Compaq nc6400 that was running 100% on the processor even on a fresh xp install. i tried install linux mandriva and when it got to the time settings it would freeze and not go any further unless i unplug the power supply! also during an XP install it would seem to "freeze" however unplugging the power would start the install again! Anytime that the power supply is connected it is running the processor at 100% It is the origonal power supply and i have not changed any hardware in the machine. IT also seems that the battert will not charge to 100% either.

Any ideas?

Hi,

I actually swapped out the memory with a fresh set of memory i have here. I have now noticed that the battery is not taking a charge at all. and the battery light is now went to orange. if the power supply is removed it is flashing orange. could a dead or faulty battery be causing this type of fault ?

You will need to get a computer shop to deal with these issues that you are having. The on-board bios battery might need changing and sometimes these are soldered on, so the shop will have to un-solder it to replace it. The other battery issue, you will need to get another battery of which the computer shop will be able to order it for you. Also make sure that the memory that you replaced is compatible with your computer, take it out and re-seat it make sure it clips in firmly.
Just a few tips to try out. :)

Please post back if you have any more problems or questions.

Try runiing on AC power only, no battery plugged in. Does it run normally? If it running normally, add the battery while it is still running, it shouldn't hurt anything. If it is still running normally, check to see if it is charging battery. You said that you get a flashing yellow light when on battery only, that means your battery is not charged enough to run the system. That being said the system board may not be charging the battery. Good news, if machine is under three years old, system board should be covered by warranty. Bad news, battery only has a one year warranty. I would suspect the system board in this situation first. If you have another nc6400, try the battery from that. If not, get the system board replaced.

We service laptops in our area, and this model is constatntly needing system boards replaced. If this were a car, the government would require they be recalled.
