I have a hp8204b charger. power light comes on, fan runs 1-2 seconds then quits. does this charger need replacement?

pin 1 positve, pin 2 and 3 are joined negative.

You have the 4-amp charger version. If you have the U1 batteries on your Pride you can replace the charger with a 3-amp version after you have your batteries load tested and tested for internal resistance. Verify batteries are good and "finishing voltage" after charging is proper. (14.4volts per battery)

In the first instance you need to check your power lead. Exchange it for another one that you know works.

The red wire is positive and is soldered to pin 1. You can see the 1 on the pin (non solder side) of the plug housing or on the solder side as a raised stamp 1.
The black wire is soldered to the negative pin 2. Two of the pins are bridged to inhibit the power chair operation when the charger is plugged in. Hope this helps.

It sounds like you have a bad charger cord. Does it do the same when powered off the battery? Like it is tryin to start up. An d also make sure battery is plugged in good to the laptop,

You must veryfi the CPU and try without battery or try it without charger with a already charged battery! This must work!

If the noise is constant then it means the problem is either:

1: a Power supply issue
2: a motherboard issue
3: a keyboard problem

the latter of the three being the easiest to fix, try booting with your keyboard unplugged or even better if you have another keyboard try using it to see if that corrects the problem.

If the above does not work then you have a problem with 1 or 2, and in order to find out for certain you will need to test it, you can goto your local computer diagnostic store to see if they can check which it is.

and hope its not a problem with the motherboard.

Hope this helps, and Good Luck

you can try to replace the motherboard, which is apparently totally UnHappy
