mwroobel,
I have one more question for you if you don't mind.
I've been using a replacement AC cord for like over 1½ years ever since the other one wore down, the cord that connects from the AC to the power supply. The label on it says 13A - 125v. Additionally I have another AC cord lying around that says 10A - 125v. I don't understand if this makes a difference or not, unfortunately engineering wasn't my strong suit. I couldn't find any info on the HDX manual about the AC cord, so was hoping some of you could shed some light here. The specs on my power supply are as follows:
Input Voltage: 100V-240V 50/60hz
Output Voltage: 19V
Output Amperage: 9.5A
Plug Size: 7.4mm X 5.0mm (Centre Pin)
Here's a link with full specs

The cord won't make any difference.
