Thanks

Hello

Thanks for the help. Unfortunately I dont want to go to use APM as that
is depreciated as you said. 

What you said about the chvt, I was really happy to hear, and I tried,
but it does not work unfortunately. Same as before, buzzing sound and
the display shows writing. (UPDATE: not only writing, but also vertical
lines, about 50 of them, right next to eachother, and horizontal lines,
about 3-4 of them far apart.) But this writing is very hard to see. Not
obvious at all. I realized it after 2 months of using it, so you can see
how dimmed it is. Also, another very interesting thing, that when I open
the lid, and the laptop is still asleep (it needs button press to wake),
as I said, I can see the writing from an angle, but only if I turn the
LCD to the left, or right, and get some sunshine on it, or light. Now,
when I press the button (space usually), it starts to wake up, and the
first moment when I press the button, I think the LCD goes off for a
moment only, and then wakes up. Why I think this? I checked carefuly,
and before I press the space bar, the text is on the display, and when I
press the SPACE bar, it gets erased, and the screen is even darker, but
only for a second or less, and then backlight comes back on.


Another thing to note, is that the text I see on the display looks
something like this:

******************IRQ Something************
*************Stopping tasks................

SOmething like that. And again, when I press the space bar, it goes
away, and finally the screen looks to be off for a moment.

Thanks

Ben
