Phone worked last night, now it's completely dead

Hi.

Last night, my Asus Padfone 2 (sadly has no subforum of it's own) worked fine. I put it on charging and fell asleep after setting an alarm. The phone was charging fine and working.

Woke up and when I realised the alarm hadn't gone off, I checked the phone. Completely dead. Doesn't react to charging, turning on, or holding the reset-combo. Nothing.

Asus have their support open at weekdays only, so I'm on my own until monday morning.

Is there anything I can do to breathe life into it?
