Problem with Toshiba Satellite Pro 5205-703 laptop display

Problem with Toshiba Satellite Pro 5205-703 laptop display
:roll: The display brightness drops to about one half after 12 or so seconds during boot, then goes back to half brightness
after getting to the desktop environment.
This is when even powered from the
external AC adaptor, so it's not a battery
problem. I've set all laptop power control options to full when externally
powered, so it is controllable via the
desktop, but only after those properties load.
Anyone have any ideas ?
I was told by their techs according to my serial number, that I had purchased a corporate laptop, so I can't get to the
BIOS, at least so far when we've tried various boot options. I am hoping there may be additional control over bootdisplay properties in the BIOS, but that's only a guess since I haven't gotten
there yet.

I presume you have spoken with Toshiba's tech's so this probably isn't anything new but on my Toshiba laptop I hit ESC just after power on and then F1 to enter the BIOS.

There are Toshiba utilities for adjusting the display brightness- unfortunately they aren't on the Knoppix disc. They can be installed via apt-get (if you install Knoppix to hdd of course).

What xserver are you using?

dmesg | less

Tried any CheatCodes

What video card do you have? How about some hardware specs?

Hi rickenbacherus,

Thanks for replying.

Right, we tried everything. I spoke to two techs, the normal one reading from a screen, and then to an advanced guy. Both had East Indian accents and as we stumbled over each others words, I asked where they were located and he said Istanbul!!! It was 7:00PM Boston time and 2:00AM over there! :shock: That's why we stumbled, not the language, but over the delayed satellite transmissions.

After trying things, he asked for my serial number and then said I had a commercial laptop, which is protected from getting into the BIOS for security. But I'm a private consumer and don't know how that happened.
He said he would get back to me in 24 hours with an answer.

That was last week.

As for your own Toshiba laptop, first, is it a "Satellite" model? When you get into your BIOS, do you see any options for display dimming after a preset time? That's what I'm trying to find out.

If not, your model could still have a different BIOS. When booting, does the display seem to dim a bit after so many seconds? When mine boots I see is the Toshiba name first, then the XP windows logo. It's at this point that the display switches to dimmer and remains that way until I get to the desktop, then switches back to full.

With the Knoppix CD, it boots and the display goes to dim after the same preset time, but remains that way all the way to the "it's" desktop.

So an MS-coded program will work in Knoppix?

> What xserver are you using?

Hmm, not sure what you mean. No server, just from the downloaded ISO image from the Knoppix website, saved to CD and booting from there.

Not really. Not really sure what to try. Just tried this program on a recommendation of a friend (he posted my original question for me). I know a few UNIX shell commands from at my old job but not really versed in a GUI Linux, or Xwindows (although I've occasionally used it on workstations). But i thought it might be good to become familiar with it since I'm taking courses in computer networking and expect to see some of this from time to time, like I did at my last job (I was a tester specialist for Lucent Tech's fiber optics).

Actually on hindsight, if it wasn't for my friend, I probably wouldn't have been aware of this problem in the first place. :?

> What video card do you have? How about some hardware specs?

nVidia GeForce4 460 Go graphics, 64m video ram, 15" UGXA display (800x600 to 1600x1200), 2GHZ P4M, 512Mram, DVD-R\CDRW, 60GigHD. The touch pad is a lighted cPad - multifunction capacitive display pad. Don't use it much though. Harman/Kardon speakers with built-in subwoofer (if you can believe that in a laptop) and built-in wireless 802.11b card.

Is that what you wanted? :wink:

Thanks,
Marcel

490CDT Satellite Pro- oldie but a goodie. 233Mhz, 160M RAM, 5.7G hdd runs Linux like mad. No such settings in the BIOS tho. I'll have a look next time I boot and check again.

Well actually yes - you can run wimpdoze apps on Linux if you want with WINE but that's not what I mean. There are Linux utilities for changing the display brightness on Toshibas.

Xwindows is what gives you a GUI in Linux. When you use Xwindows you also use an xserver, that is the driver that Xwindows uses to run your display. On top of Xwindows you then run a desktop environment like KDE or Gnome. They are seperate from the underlying operating system. (that's another huge advantage over M$). If you really want to use Linux you might want to get into the habit of opening a terminal every time you boot. Sounds like you're familiar with shell commands-open a term and enter this:

lspci -v

and you will learn more about your hardware with one simple command than that ridiculous M$ hardware manager ever thought about telling you.

Oh my, yes, you'd need something like Linux or Knoppix to breath new life into that old thing. ;-)

No, it reverts back to full brightness once it gets to the desktop. No such luck with the Knoppix CD.

Although that may not be far from what I am contemplating. It's more than 3 months old now, but I have a 3 year unconditional contract with them. Of course they stopped producing this model 3 months after buying it and is already replaced with another model with built-in TV tuner and wide screen display for th same price.

Check out the P25-S607 in the first part of the portables section at http://www.toshiba.com but mine has better sound and a higher resolution display. But I don't have any legacy ports like parallel or serial ports. Looks like they added back the parallel port in this model. But both Windows 2000 and XP have trouble with interrupts with the parallel ports and USB is the only way to go now with those OSs.

Mine looks like the 5205 "Spanish" version at the bottom of the list complete with remote control. You could click on a product tour after clicking on the "More info", but it would be all in spanish. ;-)

Now you're being facetious. :?

Okay, the "environment".

Quote:

Well actually yes - you can run wimpdoze apps on Linux if you want with WINE but that's not what I mean. There are Linux utilities for changing the display brightness on Toshibas.

So these are separate utilities not on the CD? Where would I find them? I could probably modify the ISO image so it includes these. Though the CD looks pretty full now, 699megs.

Tried that and got a tiny display still at 1024x768 but with a 2 inch black border around it. Same half display brightness tho.

I looked through the settings and couldn't find anything for changing the display resolution (it was too small to see with these tired old eyes so I booted back normally). I'm unfamiliar with the environment. But I should get used to it. I own a high powered (66mhz :wink: ) Amiga 4000 for many years, still have it, for now.

The option for laptops was ghosted and it said that "The ACM and ACPI were not loaded for this laptop and can't be used. See here for more info". I clicked and it went to the Knoppix web site but didn't have time to explore further yet.

I was amazed that Knoppix found my cable modem network connection with the default CD boot, and most everything else. And yet it didn't seem to find the built-in Yamaha AC-XG audio device. At least I didn't seem to be able to make any sound other than beeps from the speakers.

Leave the bios alone. There is nothing there to do.
I guess that the problem is hardware releaded.
Fist look if it does the same with windows. If it does then it is defently a hardware issue.
It seems that your inverter is damaged ( it is the part that is responsable for the brighness of the screen)
What I did is recovered my satellite machine with the original software and got it to a toshiba certified tech center. After 4 days I got it back with a new inverter and paid nothing as it is covered by the waranty. it is some weeks now and all works like a charm (knoppix too).
Toshiba has moved their phone support to turkey as the laber there is almost for free compeard to germany. It is a price to pay if we want cheaper notebooks, but the service is still very good at the service centers
Anyway...
Try that and see....

That doesn't sound good at all but I dunno- I'm no Toshiiba laptop expert.

No not at all- I guess I still don't see the connection. No matter tho.

Linux on Toshiba
If you're willing to remaster then no doubt you will find several apps that you could remove and gain the necessary space that way. I use the Toshutils but I have yet to try out fnfx but it sounds promising.

You can change resolution on the fly like so: CTRL+ALT+ + or -

I don't recall ever seeing that but there is an acpi patch for the kernel. I have patched my kernel with it but still trying to get suspend, hibernate and resume to work properly. I'm almost there tho.

You can specify a resolution on boot too:

knoppix lang=us screen=1024x768 (of course add whatever resolution you want.

Not sure about your soundcard- you might try this tho:

modprobe sb irq=5 Of course you should use whatever IRQ your soundcard is on or even try it without specifying an IRQ.

Now that Toshiba has moved to 'Legacy Free' laptops, there is no way to modify BIOS settings other than thruogh the "Toshiba Console' available on your Windows Start Menu AFAIK. From the Toshiba Console under 'Customizing Your Computer', select 'Power Settings', then select 'full Power' under the 'Plugged In' listbox, then click 'Details'. From the Details applet, click on the 'Power Save Mode' tab and the rest is self explainatory.

I had the same problem with my 5205-S703.

Ah, another S703 user. Excellent.

So you can't access your BIOS either?

Quote:

It's called "Power Management" tool on mine, but whatever.

Thing is, I already adjusted everything in that tool. I have everything maxed out on every sub menu I can find.

In the "Details" mode for plugged in full power, in the box it says "This mode is for maximum speed and performance of your computer."

On the Power Save Mode tab, all slider controls are slid up to maximum and the Cooling Method is set for "Maximum Performance".

On the System power mode tab I have "Power Off when I switch the power button" and "Standby when I close the lid", if that makes any difference.

So yours doesn't go to half-brightness any more when booting something other than windows?

I also have the extra battery option plugged into the aux slot on the right side of the laptop to extend it's portable power by another 45 minutes or so. But that should be moot when plugged in.

It does it with anything I boot with, be it floppy, CD or hard drive.

But with Windows, once it gets to the desktop, it switches back to full brightness.

Quote:

If the inverter is damaged, I would expect it to stay at half brightness no matter what. No software could make it change. But it does go to full once it gets to the windows desktop.

Cheaper notebooks? Are you kidding? It's the most expensive one out there. $2699 I paid. I would never have bought it if it wasn't for a grant from my Union after the company let me go.

Nope, it works like a dream now in GNU/Linux or Windows, I remember this driving me crazy when I first started using it. Unfortunately, I'm at home now and won't be able to muck around with my laptop until I'm back at work tomorrow.

I'll get back to you on this tomorrow. I'll put it back into the old mode and follow the breadcrumbs in the opposite direction and document the process.

FYI I've got the Style Bay filled with the extra battery as well.

Hmm, it is indeed the 'Monitor Brightness' slider that does it for me, under the 'Power Save Mode' tab. When I do this, the brightness stays low after it switches, and does not brighten back up when I get a Windows desktop from a cold boot.

Toshiba support for linux

Here is a link to a toshiba webpage that supports linux unofficilay ofcourse
http://newsletter.toshiba-tro.de/main/
The only problem for u is to find the european modem that coressponts to your model ( eg. 5200-701 ) see the hardware specs for details the only thing changing is the model number . Anyway you will find someting I am sure.

ps. the inverter in my case would change brithness every 1-5 minutes even after I got to the desktop

So it sounds like it's writing to the BIOS then, because this behaviour remains the same when you boot to Kroppix where there are none of those tools. And when in windows, you move the slider for the monitor brightness up to the max, which on mine says is "8", then click "OK, or "Apply" then "OK", then the monitor remains at full brightness throughout the boot process, whether it's windows or Kroppix?

If so, that's what I would have expected to happen when it's working "normally". Unfortunately mine starts at full brightness, then goes to "half" brightness after so many seconds during boot, then goes back to full brightness after getting to the desktop. With booting Kroppix, it never goes back to full brightness. I've even tried changing all the "battery" options to full power at all times with the same results.

And also unfortunately, as someone else pointed out, it's going to be very difficult to convince a repair center that it is a problem. :x

Thanks,
Marcel
