im seek Asus Transformer T100 Button Module Replacement

I am not sure what you are wanting to know. Are you wanting a new PCB with the Power Button, Volume Up/Down and Home Button? Or are you wanting the USB wall socket charging adapter (5 Volt 2.0 Amp Charger Block)?

Both of these can be found on eBay and Amazon. These sites have the original parts. For the Charger Block there are lot of aftermarket ones also, just make sure it is at least 1.3 Amp, or it will not charge properly. The OEM Charger is a 2.0 Amp, so using a lower amperage will cause it to charge slower, and using a higher amperage will cause it to charger faster. Be sure though if using a higher amperage, that you do not allow it to stay on the charger once the charge light turns white unless the T100 is turned on, and not in sleep mode. The controller for the charger is configured for optimum charging at 2.0 Amps, so using a higher one and leaving it plugged in can cause the controller to malfunction.

The part number for the Charger Block is P/N: W12-010N3A and can be found here - eBay - OEM T100 Charger Block/USB Cable

The Part Number for the Power Button PCB is P/N: 60NB0450-SW1020 and can be found here - eBay - OEM T100 Power/Volume/Home PCB Module
