Same subject only different.
Last week I set my Nokia Lumia atop of my laptop touchpad during a conference call to the States.
Loud crack from laptop and it was as dead as a culled badger in Somerset.
WTF was my reaction with much stabbing of buttons CtrlAltDel's and such.
Scheisse as DinG would say.
Winged the link call then looked to get it sorted.
Removed battery and did a cold boot.
Up and running again thankfully
Not been able to subsantiate it but the Lumia phone has wireless/induction charging and the induction fields or static from that must have freaked to touchpad.
Anybody else aware that this can happen?
