As my prs 650 now shows the well-known symptoms (without me touching any button, suddenly asking "Do you really want to switch off completely?"; going into standby out of a sudden; not going into sleep mode, but asking whether to switch off completely after only short push of the power switch, ultrafast battery drainage; etc):
Has anybody found a solution to this problem , except than avoiding the use of the power switch completely, or by exchanging the reader for a refurbished one?
I am really disappointed: the reader was not cheap, and looked quite sturdy. Now it merely lasted 18 months only, the device's life time as projected by Sony, it seems

.
I do not think it is wise to look for a used one: the problem seems to be quite common, and I fear a used reader will show the same defect sooner or later, won't it?
At least from the outside, the power switch of the prs-t1 looks similar; so there might be the same design flaw with it. Any experience?
