I have just registered to contribute to this thread. I have been following it for some time being the proud owner of an S5100-501 with the same fault as all other worthy posters here. I agree that it’s a nice laptop, shame about this fault. Now, I know all this has been gone over time and time again, and confess in advance to probably having missed a few posts, but I would like to clarify the situation and ask a few questions with regards to my own experiences with this problem. Sorry it’s a bit long-winded.
First off, as some people seem to have abandoned all hope, I’ll run through my temporary fix which has been working for about six or seven months now, cobbled together through links posted to this thread:
Fan.exe turns the fan on to about 25% and keeps it there, also allowing the auto-controls to rev it up higher when it gets really warm (if it hasn’t already crashed):http://www.buzzard.me.uk/toshiba/windows.html
and click the ‘here’ link.
Speedfan helps me to keep an eye on the temperature and sometimes lets me manually force the fan faster for a few seconds at a time, but it seems to lose even that control when the PC is really hot, which sort of defeats the object. It doesn’t fully detect the ACPI fan, so control is limited.http://www.zdnet.nl/downloads.cfm?id=48934
Task Manager helps monitor processor use and what program is using it.
Nothing gives full manual control over the fan speed so this isn’t perfect - heavy Photoshop work, for example, causes overheating. Neither can I play graphic-intensive games (not that one has time for such frivolity!).
Turning to the cause of the problem. I had noticed how hot the laptop had been running for some time and thought there might be a problem, then it started going pear-shaped. I tried replacing the nVidia card with an identical used card but had the same problem. It may be that the replacement was equally faulty but it came from a reputable part-sourcing company and I can only assume (hope) they tested it, but who knows… This suggests, in agreement with Cheebster, that the fault lies elsewhere.
An interesting thing that all this close monitoring has bought to my attention is that on odd occasions seemingly innocuous processes cause major (100%) processor work and rapid heat increase to around 80-85°C (Nearly-boiling°F). Sometimes it happens during MS Word “Spelling and Grammar” checks for example, further supporting the fault not being the video card.
So I was wondering:
Does everyone with the fault use Windows XP? I thought maybe it was a driver issue that made XP behave a bit strange on occasions that is causing the overheating.
What fix are you trying Cheebster? Reworking the soldered bga connection on the video chip or processor or what? NOTE: I am an ex-techie of four years now, so not really up-to-date on the patois. I believe it is useful, for everyone’s sake, to make descriptions as accessible as possible.
If the problem exists, could the component be damaged, probably due to overheating, which no amount of reworking will fix?
What caused it in the first place, poor heat dispersal, poor quality chip or workmanship?
What happened about the class action from last year? Have Toshiba said anything else on the issue; after all, this is clearly a design flaw.
Regards and thanks for all the efforts of the people here so far,
