I, too, own a Satellite 5205 for the past three years and after having it repaired once about six months ago--where it sat for two (2) freaking months at a local *Premier* Toshiba ASP--I found the real problem wasn't the laptop...it's the woefully incompetent tech(s) repairing it, and at a *Premier* Toshiba ASP of all places.
Long story short: the laptop went in under the extended warranty coverage for hard disk, optical drive and LCD hinge replacement. When I dropped it off, it was is very good physical condition with its plastics in perfect shape and its motherboard was working totally perfectly with no issues at all. There were no thermal issues, spurious power issues, or video issues to speak of.
Then I waited. And waited. And freaking waited for news that they had repaired it. Then one day six weeks later I get a call from the ASP saying that laptop's good to go and I can pick it up at any time.
So I drive out to the ASP to pick it up. Then is when the fun started.
At first sight I found that they had completely customized the glossy metallic blue LCD lid--which was in mint condition when I dropped the laptop off 6 weeks prior--with scratches galore. The LCD bezel's screw covers were missing. And the failed optical drive? It hadn't even been replaced at all.
When I powered the laptop up things didn't get any better. In less than 30 seconds the LCD started showing flashing bright green vertical streaks and then climax: I get a blue screen of death.
Needless to say, I was freaking pissed.
So I tell the ASP to fix these problems of their own doing and to call me when it's repaired correctly. In the mean time I get in touch with Toshiba's global customer support.
The first thing Toshiba tells me: I should've used Depot Express instead.

Freakin-A! If I'd have known that maybe that could've saved six weeks of my time or so I thought.
But it gets better: what follows then was a veritable circus of daily calls between the ASP and Toshiba to get my laptop fixed. Day after day it was the usual BS: the ASP says they can't fix the laptop without replacing the failed optical drive but they can't replace the failed optical drive because they don't have it and Toshiba says they can't expedite the shipment of the optical drive because the ASP hasn't ordered it in the first place.
Finally after another two (2) freaking weeks of this, the ASP finally sorts their sh!t out and returns my laptop to me fully repaired with a brand spanking new virgin LCD lid to boot.
My only consolation is that thankfully the laptop's been running perfectly ever since.
But next time I have an issue that's coverable under warranty, I'll be damned if I'm going to just drop off my laptop without checking that the tech(s) that'd be servicing it are truly qualified to work on it in the first place.
