Power lead is working but netbook not charging

check wires from rectifier for corrosion, is battery ok

Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter 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.

Hi,

You just need to set black & decker charger to 12V . Don't make mistake while connecting + / - leads. + lead usually come with Red color cable. You can use the AVO tester to justify the lead cable. The charging time is normally about 10 -12 hours (or just just check the status on your charger display). If your charger does not has trickle charge facility, you have to disconnect your charger after 12 hours continuous use.

Also, you can find the guidance about your charger here :

This is not the motherboard. The batteries in laptops have electronic sensors in them. When they reach the end of life, they stop the computer from turning on. Once that happens it wont power on with the battery in or out. Batteries are not that expensive. Only about 25 dollars.

It is corrected properly, right? + to the wiring harness and - to ground ... right? Are you certain about the rectifier? Is the battery charged at this time?

You know a alternator cannot make power unless you first put power into it ... right? Alternators (unlike most generators) are not self exciting. If your battery is weak or "dead", the alternator cannot make electricity to charge the battery. I don't know what the rating of your alternator is. Your battery should be fully charged before you do any more tests. If you have a 1 amp charger, allow at least 10 hours for a full charge. Don't cook your battery with a big, powerful, fast charging automotive battery charger.

Good luck with your repair ... I hope you find this response helpful.

Thanks for your question @ FixYa.com

First, you need to make sure your power adapter is providing enough power to both run the netbook & charge the battery. A very good way to do this is to compare your netbook voltage & ampere requirements (written on a sticker on the bottom of the netbook ) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the netbook's voltage rating. Amperage of the power adapter should be at least equal to or greater than the netbook's rating. It should never be less than the netbook's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the netbook, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the netbook & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another netbook, or try a good or new battery in your netbook.
If this did not work, there might be a possibility that the charging circuitry on the netbook's motherboard is defective & needs servicing. In order to do this, the netbook needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the netbook's motherboard altogether.

A battery that might sit for a month at a time, would only need a trickle charge or about 1 amp, a charger of this type can stay hooked to the battery for the whole month. A 10 amp would be for a quick charge or only about 4 - 12 hours depends on how fast the battery lost the charge. A 10 amp charge would cook the battery if left for days.

Leave it plugged in for about 10 minutes. The battery just needs to charge a little more. Then you can come out of sleep mode.

If it is locked in sleep mode. Just hold the power button down to shut off the computer. Let it charge, you can now reboot, and keep charging after about ten minutes.

bad battery.. RMA that back to where you bought it from. probably wasnt a new battery they sold you. id charge it from completely dead to completely full one more time and if you dont get at least an hour out of the batt then i would return it..
