New battery won't work

maybe your battery or your phone os .... try a new battery if nothing happens... try re flash your phone

Is it a replacement battery? Are the specs the EXACT match, DC volts and Amps? Some inexpensive batteries do not work well with your laptop, it's a Connector/ pin thing, they don't communicate with the laptop. Try pulling the plug and drain the battery and recharge. Cycle it a 4 times, drain/ recharge. Does your BIOS setup have a Battery Learning section?

POWER SUPPLY & BATTERY PROBLEM
If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

Battery could be dead and won't hold another charge. Batteries only last for so long until you have to replace them. If you laptop is ok with the AC Adapter & Power Cord meaning it boots and allows you to work in windows, then the battery is definitely dead.

Sounds like you need a new battery.
It's not just a battery in a case, it also has a small circuit board inside to control the charging etc, if that's faulty it won't charge, or if it has dead cells in it won't charge.

I would say that you definitely need to purchase a new netbook battery. If it's only turning on when plugged in, then the battery itself doesn't have any more charge cycles.

Hello,
If the battery won't charge and the laptop won't turn on but the ac adapter works with other laptops, then the problem is the port where you plugin the ac adapter. Some of the laptops has it built in to the motherboard. So you might need to have it repaired by a technician. Or if the laptop is still in warranty, you might need to send it to the manufacturer to have it repaired or replaced. But if the laptop works without the battery, or it will turn on but the battery indicator is not lighting up, you're facing one of these problems.
1. The battery itself is dead. 2. the battery bay is loose 3. the battery itself is loose
Hope this helps...

Now you have a good battery & a starter that turns over the motor

Have you cycled the key on & off with a fuel pressure gauge on the
fuel rail?

Do you have a fuel filter that isn't over 3 or 4 years old?

Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance

If you removed the ducting & MAF Sensor it won't start

Tell us what you checked & exactly how that was done.

In a laptop, you can lose power in three ways.
1. Dead battery 2. Dead Power cord. 3. Bad motherboard.
ther first two should be rather obvious, as the battery won't work or it won't hold a charge, but if it won't turn on at all, even while plugged in, chances are that you're going to need a new motheboard. This can be expensive in the M--x laptops, unfortunately.
Sorry for the bad news, mate.
