Nice message. It reminds me of myself when I am sending a support message in between patients. :-)
Read your message again and re-word it if you want a response.

Sorry I was in a hurry. I got 2 Scribbler SC2200 from a friend and one of them works and the other one dosen't. He was using it one day and it just shut off by itself and he turned it on but the screen was blank and I connected it to a monitor using the port on the side and still a blank screen. The power light and battery charging lights are on and the hard drive is running but no video just a blank screen. I thought it might be the hard drive or ram so I swapped it out with the good scribbler that works but still blank screen. The ram and hdd out of the broken one worked in the one that works.

Do you see the BIOS information go by when it starts?
Try Safe Mode on boot.
Try pulling the battery out and leave it out for 3 minutes before putting it back in. NO AC plugged into the unit.

If above fails, it sounds like a video card or wired connection problem, but I am certainly no expert. I think a call to EV tech support is in order.

No I don't see bios nothing comes on the screen likes its not turned on. I've tried taking battery out and using it with no battery and plugged in a/c. EV tech support said to take out the battery inside it. Its acting like a bad cpu. I have fixed a few desktops with those symptoms and it was a bad cpu but I don't know how to take it out or where its located. I can swap them from the one that works and see.

A bad internal battery (CMOS)would keep the unit from booting (no Bios) and explain why the Bios screen never appears. I've never looked for this battery but hopefully it is easily accessible from within some area that is readily accessible.

Now that I think about this issue, I actually had this exact thing happen to me two years ago with my Scribbler! As I recall it started when I swapped an old battery from a 2100 into my 3000 or maybe it was vis versa. The unit would not boot at all. Blank screen, no bios, nothing.

Here is what I did from memory: I removed the battery completely, [u]waited a few minutes </u> and started the unit with AC only. NO BATTERY. This worked for me, as I could then boot to the desktop. I then shut down the unit and replaced the battery and all was fine. Has never happened again. Even if you have tried this, try it again and but make sure there is no battery in the unit with you plug in the AC. Maybe even unplug the AC before inserting it again.

I always felt this was an electrical problem where my battery swapping technique (slam bang) caused the unit to shut down as a misguided safety precaution.

I replaced the cmos battery and it worked. Thanks for all the help.

Glad you are a go! Where is that CMOS battery? Under the regular battery?

Its next to the hard drive. You have to remove the hard drive to see it but I had to remove the cover to get to ot.
