I have an update on my personal charging issue on the Sola 800.
I am revisiting this subject, due to my old Sola 800 totally refusing to wake up this time, after retrying every step I had used previously when the light had sat unused too long.
I have struggled with it refusing to function or re-awaken for the last 4 days, and had begun a dialog with L&M.
Just a bit ago I finally (I think) have gotten somewhere.
After many, many attempts over the last 4 days to wake the Sola 800 up, yesterday I got it to suddenly go into SOS mode while plugged in, as I accidentally pulled the button back during the wake up procedure. The SOS continued, and could not be stopped, but went out as soon as I unplugged the charger.
In the meantime I have kept researching comments and suggestions on ScubaBoard and other sites, and trying everything short of disassembly.
I continued trying the 5 to 10, to even 20+ seconds of "wake the damn up!" pulsing the contacts, and then plugging it in fully, but every time after a while on the charger it would light 1 red LED and the light would come on bright. Moving the switch had no impact at all on this.
No change from this in 4 days of trying!
I discovered though that sometimes after the wake up failed, if I would try turning on the light after unplugging it, it would very briefly light up and then just as quickly go out.
I kept trying the 5 to 10 seconds wake up. No help.
Just now though when I unplugged the light after another failed wake up, when I unplugged it I pushed the button forward, and in that brief moment when it was lighted, I repeatedly tapped the light sharply against the palm of my hand, as I held the button forward while it was still lit.
Suddenly the LEDs flashed green, and the light seems to have reawakened!
The light is now telling me that the light is charging, flashing the series of green LEDs and the charger is showing red, which seems normal.
Fingers crossed. It has been showing charging now for the last half hour.
