mine has done this a couple of times now since i bought it new in december. it always seems to be when it gets a bit "too" empty. always i've been able to recover from it by doing some mixture of charging/powering on etc.
last night i came to my 101 and it seemed to have suffered the same fate.... so did the usual tricks but it isnt waking. the light is coming on and turns off after holding it down for 7 secs but i see nothing on the screen. last time i checked it a couple of days ago it had about 60% battery left. Is there any way of determining if it is truly dead or if the screen is dead (plugged into usb but not getting any of the usual beep bop noises, but i think from memory you had to select to use it as storage device within android which i obviously cant do)
So now i'm crapping myself since I am totally at a loss as to what i can do. its never been opened etc but I installed the dev rom. I cant honestly think that Archos could possibly put ANY hardware issue down to the fact you had a dev rom installed

(bought from currys, uk if it makes any difference... no doubt they have no stock to replace so most likely will say that they will have to return to archos)
Any advice much appreciated

thanks
