Won't come on

If the rechargeable 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.

Hello, guys. You can try these OBD2 tools to find your car problem.

1.Check the device's battery level for at least two bars of strength.
2.If the battery level is low, charge the battery.
3.If the issue is not resolved, remove the back cover.
4.Remove the battery.
5.Wait 10 seconds.
6.Press and hold the W key.
7.While pressing down the W key, re-insert the battery.
•The device restarts and after approximately 15 seconds, the 'Recovery' screen appears
•Release the power button but *continue holding the home button*, for another 30 seconds.

The power supply adapter may not be delivering enough power when you run it and trying to charge the battery at the same time. The only way to find out is sub another power supply.

how old is your laptop?

Unfortunately, batteries have a shelf life. If the player sat for three years without being charged, the battery is probably bad. The chemical reactions inside the battery continue, even when it's not charged.

My advice is to replace the battery if possible.

Good luck!

You have two problems and they are separate issues.
First your battery is nearly worn out. Rechargeable batteries have a finite number of charge and discharge cycles and as the battery ages the charge capacity will drop. When the battery is worn out, it may not charge at all or show it is 100% charged but when you remove the AC power the laptop will shut off because the battery is dead. A new battery is required to fix this problem.

Second when you connect the AC adapter into the laptop's power socket, and the screen flickers and the charge LED also flicks, it means the power socket is faulty or the power socket has a dry solder joint connection to the motherboard. If you hold the power plug in a particular position you should notice the charge LED will stay on without flickering as well as the LCD screen.
This fault can be repaired, but it requires the laptop to be dismantled completely to access the power socket. I suggest you get a quote first.

You need to reprogram (flash) the phone. Go to a nearby shop, they can do it for your for a little amount of charge.

i happen to me you need to find a friend or a family that has the same phone that you have and that your problem solve!

I've had 2 and 1 did that to me i switched the battery-and that fixed it but then it wouldnt transfer any more songs so ! At the top right theres a phillips head screw-remove that and pull it out just a little then turn it as theres a little catch in the middle of it,if you try to pull it straight out it may break so turn it while you do so it will come loose just have to kinda twist it or you can slide a credit card down the side til you feel it then it will open/look the 2 i have dont work no more for the cost of the battery ill send it to you say 10 $ and no i wont send it to first then etc... but if it was me i would just get a different model like an apple
