Question about HP Computers & Internet
Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.
Possible troubleshooting steps and repair solutions:
1. Test your compaq tc4200 power supply with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.
2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.
3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

It sounds like you have a faulty power jack, and possibly a dead battery as well. You should take it to a person you may know that can order and solder a new one in or take it to your local electronics repair shop. I do repairs like this on a daily basis for my computer business.

If your system won't boot up with just the AC adapter connected, it means to say that there's a problem with the AC adapter or the motherboard of the computer. Basically, if the AC adapter or the motherboard is damaged, you won't get a charged battery. If there's another AC adapter that you can try your computer with then that will be great. If antoher AC adapter works, then you just have the AC adapter replaced. If a known AC adapter didn't work then you may need to consider replacing the motherboard of the computer.

Either the electronics in the charger or the battery have failed. If you still have any warranty left on the laptop call Dell support and they will assist you in identifying which one has failed.
