remove the battery and see if it works fine, use only the power supply. If it works the problem is the battery if not you need to test your power supply. That's the easier way

Your power inverter most likely has died or the connection between the inverter and the wall outlet cable has come loose. Most computer retailers sell universal power adapters you can test this with.

Remove the battery and hold down the power button for 10 seconds. Try powering on without battery in.

Make sure all power connections are firmly connected.

Check the voltage output from the charger and see if it is within the range that is stamped on the charger body (eg: 20 volts) If it is below or above this, then the charger is faulty. If the green light is flashing on the charger, it means that power is "not being accepted" by the laptop and this indicates a faulty charging port / circuit.

Computer will not turn on

Try a different power outlet
check whether battery is completely drained out
check for a battery meter behind the battery which can indicate whether the battery is completely drained off or not
check whether the system ppowers up with the AC adaptor connected
check whether there is any lights lit on the system indicating some activity is happening

If the power supply is powering the system without the battery installed, and the battery powers the system without the power supply attached, but the power supply will not charge the battery in the system...chances are very high the charging circuit on the systemboard is not functional. There are a few possibilities as to why but the only real solution would be to replace the systemboard since the charging circuit is integrated. You could run through the charging circuit to locate the exact fault but you will need schematics in order to resolve if you are comfortable with micro-soldering.

To verify, if you can, place the AC adapter and battery into another 1737 and see if you get charging on the battery.

Allen -

It sounds as though you may have either blown the power supply, or burned the power circuit on the motherboard. That buzzing sound usually indicates an electric arc, where electricity passes through open air from one contact to another; In this case, it was probably caused by a loose or broken solder connection on the laptop's power jack.

If you can get your hands on an identical or equivalent power supply, test it with your laptop. If it works, then the power supply just needs to be replaced.

If not, try taking the battery out of your laptop, and plugging it in again. Sometimes, when a power supply burns up, the battery will discharge, rendering it inoperable.

Hope this helps!
