Well, it finally happened. The Medion couldn't take it anymore. Had disassembeled it to clean it. Re assembeled it (all but 3 screws) and tried to boot. It worked fine. Turned it upside down to plugin the last 3 screws which hold the "case" together. Tried to boot again, and it started to boot, but nothing came on the screen.
When the Medion boots up, it's like on IBM Desktop computeres where all tha fans run full speed at start up for a couple of seconds. Very noisy.
The Medion never got past the noisy point. It just hung there and made a lot of noise. After trying to boot several times I tried to disassemble it again, checking if some cable had gotten detatched. There was no such thing. And by now I had run out of patience. The Medion called it quits after 5½ years. Sold it to some guy who wanted to fix it. Took out the harddisk before I sold it.
In stead one of my fellow students had an IBM T60 for sale as he wanted a Mac instead. So I bought his T60. Wow, what a machine. I am very satisfied with it. IBM spells quality compared to the Medion I think. But hey, it's newer machine, and was quite a bit more expensive when it was initially bought.

Medion Laptop trouble...
My Medion MD5400 has really started acting up. Some times it woun't start up. Just comes up with a black screen stating "No operating system found". I found out a trick that works. Turn the laptop upside down and then shake it a little. Voilá! Then it starts up. Usually. There must be a bad connection somewhere. But where...?
Over time I have modified the original. I changed the harddrive from a 40 GB Hitachi 4200 RPM to a 60 GB Western Digital Scorpio, 5400 RPM. The Scorpio is much more quiet. And faster.
I put in extra ram. 2x 512 DDR Pc-2700 (200 pins) and last but not least I changed the CPU from a Pentium 4, 2.53 GHz, 553 FSB desktop to a mobile Pentium 4, 2.0 GHz.
The desktop CPU got way too hot, and as a result the speedstepping feature caused it to go as low as 300 MHz. It's a known problem for this laptop.
I had to put in a little copper plate (1 mm) between the cpu and the heatsink to make sure that they touch. The temp. dropped about 10 degrees Celcius doing this trick. Also the mobile doesn't use the speedstep trick, so it always runs full speed. Or at least 1.6 GHz.
And thats another odd thing. It is a 2.0 GHz CPU, and detected like that i BIOS (or at the boot screen) but in Windows XP it runs at 1.6 GHz. I can't figure out why.
