Hi! I recently got a Contura Aero 4/33C from a friend. When I try to start it, the only thing that appears on the screen is 4096 KB OK. What's the problem here and how can I fix it? I need this notebook really badly, I hope someone can help me with this!

Could be the CMOS (BIOS) battery is gone (with a notebook that old it wouldn't be a suprise) or a hard drive that's went to bit-bucket heaven. Leave it on for several minutes and see if any error messages are displayed.

Try a dos 6.22 disk 1 to see if that will work. Turn computer off ,install dos disk 6.22 1 and turn on computer... then see if it will boot.

You can download a simple MS-DOS Bootdisk from my Bootdisk Project Page. (Link above) Turn Laptop off. Insert Bootdisk Turn PC back on and you should get MS-DOS message and A:\ Prompt. I all is OK. Type SYS C and press enter. remove diskette and turn off. Turn Laptop back on and it should now boot to the C:\ Prompt. Read the notes on the Bootdisk Project page on how to create a bootdisk. Please reply with a message to let us all know we are on the right track with your problem

Hi guys, thnx 4 the replies! So far I tried T-R-A's tip, about leaving the notebook on for some time but after a couple of hours nothing else beside the 4096 KB OK appeared on the screen. I just downloaded the Powerload files to a clean disk, thnx Mick, so I'm gonna try this next when I get home. I'm not sure I understand the notes on the bootdisk project page, I'm not that familiar with all this, especially not in English, so I installed the MS-DOS 6.22 Bootdisk and mback622.exe on my disk. Please tell me if I have it wrong!

on that compaq when it starts showing the ram test start punching the f10 key to try to enter the bios

It works!! My notebook works again, thank you all for your replies. Mick, thnx for telling me about the boot disk, when I started the notebook after having used the disk, it started working! I'm so glad I can use the laptop, thank you very much!!
