Wont charge and get get it to stay on,

There are two troubleshooting tips for this:

• try changing the battery. Sometimes the battery can be bad, not keeping a charge long enough to allow the computer to power on.
• Try a new power cord. First thing is, there can be a short that intermittently causes the computer to show as charging, but it stops actually charging after letting go of the plug. Second, the cord is going bad and not allowing a full charge to go through.

bad cable or bad battery. I bought a power supply for computer and power cord was actually bad. had a spare and worked like a charm.
usb connectors get misaligned sometimes. the cables are cheaper then move on to battery.

It is the cord, it probably needs to be re-connected properly.

Your battery maybe out of charge. Thats why nothing happens when you press the power button. The battery may not be charging because the power cord might not be working. Try another power cord.

Try removing the battery and plugging the power cord and switching on the computer. If its the problem with the power cord the computer wont start. If it starts, the power cord is working fine.

it sounds like your power adapter isn't supplying enough power to the unit. You should be able to try switching out the adapter with another and see if that helps. If the doesn't help, then there may be a problem with the recharging circuit on your GPS. AT which point you should contact TomTom.

If the laptop is old think about changing the battery.

Stelios.

Sounds to me like the transformer circuit that enables the batery to charge. If you have bought your machine within the last 12 months it should still be covered by warranty so go back to the supplier. If not covered I wouod still try as it is not beyond reasonable expecations that the machine will operate perfectly in very way for more than 1 year.

Either the power supply has a loose connection or is faulty.
You can try removing the battery pack, press and hold power button for 3 seconds and then put battery back in and see if it corrects the problem. You can test power output from the supply to see if it is putting out the voltage it states it should on the label of supply.

You either have a bad battery, or a bad power supply that charges the unit (power cord). If you have a friend that also has a PSP, try swapping out the battery to see if that works, and or try another power cord to see if the charging indicator light comes on. I think that possibly your battery is dead and the power cord might be bad. You can find good deals for both the battery and cord on ebay. Good luck!

Try booting into BIOS. If it stays on than you need to reinstall your operating system.
