Default AW: My tablet dosent charge!

Your new charger might not supply enough amperage for your tablet. I take it that charger isn't an Asus charger, is it?

Just to clarify, the TF NEEDS the ASUS charger to show that the unit is charging. If you use a standard charger or charge from a standard USB PC port the TF will take many many hours to charge and there will be NO indication that it is charging.

The ASUS charger has a themal cut off in it, you could try putting it in a sealed plastic bag and then in the freezer for a few hours, that should reset the charger if that is the problem.
If it is the cable than connecting it to a standard USB connection and waiting at least 4 hours it should show a 20% to 30% charge. If not than it's either a bad cable or a problem with the TF.

Buy a new charger made for the ASUS laptop. The good thing is that it is not the TF.
Still could be a bad cable or a bad charger.
You can buy an ASUS branded charger for around $30 or look on Ebay.

FYI the TF needs 12V plus(ASUS charger puts out 15V) to charge normal USB is 5V.

It could still be the cable. The TF charging voltage doesn't kick in unless the cable detected is at least USB 3.0 - meaning it needs those extra pins. Through grounding out certain pins the charger is told it's connected to a TF and kicks in the higher voltage. If one of the pins or the cable itself is damaged it could fail to ground and hence fail to signal to the charger that it should pump out the voltage the TF expects.

I leave my charger and cable plugged in to each other 24/7, using a USB 3.0 6 foot extension cable between them. It works great and pretty much means no stress on any of the connectors from accidentally pulling it out at a bad angle for instance.

I recently experienced this issue, I purchased an new charger from Amazon (Asus original equipment) and before I received the new charger a couple of things happened which I'll document;

1. I went back out to the outlet where I normally charged, and it worked with the old cord, so I experimented. I noticed the plug is not polarized which menas that you can plug it either way into the outlet. I found that when I switched direction it was plugged in sometimes is all that was required (reversing polarity).

2. I have also noticed that sometimes when plugging into an electrical extension cord (old style 1 plug 3 out) that sometimes it does not matter how it's plugged in, it will not work, I am guessing this is an issue with the cheaper nature of some of these extensions. I have not had this problem when pluggin into a power strip however.
