Well, I've bought that thingy in october, and i do have quite a story to tell...
Sys specs: 3.0 Ghz P4, 512 MB Pc266 DDR-Ram, 80gb 4200rpm Harddisk, 128 MB ATI Mob. Radeon 9600, 2.4x DVD+RW
When i returned home after buying this beauty i fired it up instantly, and noticed severe harddisk rattling... The hardware store refused to exchange the notebook, so I had to pay my local Fujitsu-Siemens Bring-In center a visit. After 3 days of waiting I finally got my new disk and was ready to rumble.
The first thing i noticed was the really amazing screen. The resolution was a bit low for my likings, but after some time I got used to it. No dead pixels here.
After a quick windows install, including dx9 and putting all the necessary drivers on, I immediately scored about 9100 points. Some overclocking netted to 9700 pts in 3dmark 2k1. I can't remember my 2k3 scores from then though.
Some days later, due to some extreme overheating caused by the notebook being placed in standby whilst being in my bag, I had to visit Fujitsu again, to order a replacement case (luckily i could make them believe the laptop overheated itself without any interaction from my side heheh). That thing wouldn't even sit plainly on my desk.
Some months passed, and Fujitsu was still unable to swap cases because they couldn't find one(?). Instead, they changed motherboard, cpu, ram and the DVD+RW drive, because they thought there might be some problems evolving due to the system having overheated. That did no good, the notebook produced one bluescreen after another. After some bugging around, I found out that those idiots forgot to fasten a screw, which was happily rolling around in the case. After that, no further problems. Well, except the case.
In April, I encountered more problems. Fujitsu finally received a small part of the case. After replacing it, more bluescreens turned up, but this time it turned out to be more severe: No screw rolling around, so it had to be something else.
Two days later they finally declared it as being irreparable. Yay, finally a replacement notebook! After three weeks of waiting (They had some severe shortages factory-side), here it is, my new Amilo.
Funnily, though having the same system specs as the old one, I now score 9500 out of the box, and 10850 with severe overclocking (10450 using moderate overclocking).
A final word on the DVD+RW Drive. THIS DRIVE HAS GOT TO HAVE THE WORST F****** ERROR-CORRECTION EVER!!!!! It can't even read discs only mildly scratched, discs my desktop DVD drive can read at 40x speed!
As you can see, my experiences are somehow two-fold, but it is still a nice gaming laptop. And really exceptionally quiet for a P4 machine! The Inspiron 8600 of a friend of mine is a lot louder when gaming.
Well I guess I've got to put up with that
