ARCHOS 70 WON'T CHARGE
there are three things involved. Problem is either from the charger, or battery or charging port.
A defective charge can cause a unit not to charge. To actually find out if your charger is defective or not, borrow a charger from a family or friend that has the type of your tablet PC, use the borrowed charger to on your tablet PC. If the the tablet PC charges, then obviously, your charger is defective and need to be replaced. It is also good to test your charger on another tablet PC to confirm the status of the charger.
Make sure you run the above test, before buying another charger so that you don't waste your money. Sometimes, charger might be working and tablet PC won't charge due to some other reasons that would be discussed below. So confirm first before buying another charger. Don't buy another charged based on assumptions........
A battery that is very flat, I mean a battery that its cell is very weak, won't charge with a phone charger. You might have to leave the battery in the phone with the charge plugged in for some minutes or hours before the battery will begin to charge and other times, it might not charge at all.
What make batteries to be in this kind of condition is;
1. If you use you tablet PC to the point when it says "low battery" and you still don't charge the battery and the unit turns off by itself. This can run down a battery cell.
2. If you leave a battery in the tablet PC idle for days or months, the battery cell will become weak. Or if you leave a battery used for days or months.
3. If you don't use the correct/right charger for your tablet PC, this can drain the battery instead of charging it.
Batteries in such condition will have to be fast charged with a desktop charger. The desktop charger will be connected directly to the battery and the battery will definitely pick up within 1 hour. Thereafter, you can continue charging it with your tablet PC charger and it will charge immediately.
But if the battery is defective, it won't charge at all. Even if you use a desktop charger. Such batteries needs to be replaced. Also, it is good to test the tablet PC with another battery, and charge it to confirm before buying another battery.
If non of the above seems to be the reason why your tablet PC won't charger, then it means the charging port is defective.
Most times defective charging port confuses people. They think the charger is the reason why their unit won't charge and after using another charger on the unit they still find out that it still does not charge.
Once your tablet PC doesn't charge, the first thing you test is the charger and second, the battery. But if the battery and charger seems not to be the cause of the problem, then it is the charging port that is cause the problem.
Your charging port might not be defective, maybe it loosed contact with the phone phone or it shifted from it's position. Sometimes, the way we forcefully insert our charger into the tablet PC can make the charging port loose contact.
At this point, you will have to disassemble your tablet PC. But if you feel it is a task you cannot perform yourself, then take it to a repairman to help you out. But if you feel you can do it yourself (DIY), read further.
Turn off the tablet PC. Remove the battery. After that, get a screw driver, unscrew all the tablet PC screws, remove the tablet PC's cover in order to gain access to the panel and get to the charging port.
Check if the charging port actually loosed contact. If it didn't loose contact, then you will have to replace the charging port.
Note that some charging port are soldered to the tablet PC board and some are not. So if yours is not soldered, simply remove the charging port and make a replacement. But if is soldered, you will be needing a rework station. Rework station is what you will use to remove the charging port.
Have the above checked.
