  Toshiba Satellite 1800 Auto Power Shutdown 
 Date Written 
M Logix Jan 20, 2005, 11:59am EST Report Abuse

I have got a problem with Toshiba Satellite 1800. It automatically shut down after an interval of time.
I unmounted CD drive, Batterry (use with adaptor) and even Hard-disk and then started testing again.
A few minutes later, it automatically shut down again. But if I'm in BIOS setup, it lasts for the whole day.
You guys have any idea? Thanks in advance.

>> Re: Toshiba Satellite 1800 Auto Power Shutdown
Here is our Satellite tale of woe. Does it sound familliar to anyone else. Has anyone found a good fix?
When plugged into AC and booted up, the green plug light shows on the front. The computer on light glows green. The battery plug is variable. It can be red or blinking red or green or not lit at all. In our case, it is never green anymore and here is why. While plugged in and booted up, if you go into the control panel and look at the toshiba power management area, this is what you see. It shows that the AC power is on. It shows that the battery is, for example, charging. Then, for no reason, it starts using the battery! The battery gets used, is shows it as discharging, until the power becomes critical and if left alone, the computer shuts off. Sometimes, if you catch it at about 30% or so, you can pull the plug and plug it back in and the batter will go from discharge to charge and you are back in business. Other times, no matter how many times you fiddle with it, the battery mode remains dominant and she shuts down. When that happens, you have to wait a bit before turning it back on because the machine seems to need a bit of battery to boot up. I have looked around on line and this doesn't appear to be an isolated problem but I have not seen any useful suggestions for fixing it. I don't even know if it is a hardware or a software problem! We have two satellites, one with the problem and one without. Tried swapping the batteries and or the power cords, didn't make a difference. Suggestions appreciated.

This issue is due to a problem with the old bios....update your bios and it should
resolve this. The latest bios can be obtained from toshibas website....

Has anyone tried this solution yet?Does it work?And how did you do the update?Windows based or
by using a floppy disk?I'm pretty scared that the laptop might shut down while updating.What do you think?

I installed the update (from 1.1 to 2.x) and via the Windows file, was pretty easy ; just let the update sw do it's work and don't touch it during the update process.
I updated it 2 days ago, but got mail from the client this morning that it happened again, so back to []1

This is bad.So I didn't go for the update anymore.I removed the battery,and used it plugged shuts down indeed,but only if I try a deep hard disk scan...funny!If I do a registry scan,everything works fine...but when the HDD is being used intensively,it shuts down.Any ideas?Did you go to your customer?What did you notice?

I found on another website that another reason for the expected shutdown is : overheating.
I asked my client if the 1800 was warm/hot when the shutdown occured and it was very hot! I went over and cleaned the machine from dust (that was there in heaps), restarted and works fine sofar.
At the rear just below the screen there are also minute ventilation holes that need to be cleaned. I just used a household vacuumcleaner at low speed (300w).
Let me know if this works for others too (that is : upgrade Bios and clean 1800) !
I will keep you posted too.

Hi! It is most likely that you found the topic I opened on notebookforums.I am Inch'Allah(nick name obviously,my name is the one on this forum:P:P)----nice to meet ya!
So....indeed,this was my first seems that the bios upgrade+the cleaning process should do the trick.But I'm scared to work inside the lappy.What do you recommend.Could you post some details?Is this by any means risky?Thank you.

I am no (too) afraid to open the machine; just make sure you discharge yourself from any static electricity you may have built up (just touch e.g. something metal , like your seat etc.(not the drive, memory etc))
Ten carefully inspect the screws and see if you have the proper tools (philips and torx). Gently lift the parts and use the vacuumcleaner the clean near the fan-area, afterward check if the fan works smootly.
Also: just thought of this, we can install software that monitors the CPU temp as wel (not sure if that is supoorted by the BIOS) but will look into that too.

I also have one of these notebooks(1805-S253) and have spent countless hours searching for an answer, and alas....i found one right outside your very own door. please check out this link below (in portable hardware)). the bios upgrade is recommended as well. it allows the cpu to throttle down a bit and keep from overheating.i opened up the CPU cover on the back of unit useing a #6 torqs bit. i then unscrewed the 4 corner screws on the heatsink allowing the heatsink to come away. i cleaned the cpu off and applied arctic silver thermal paste, then put it all back together. i then used my air compressor to blow the dust out. its been a week now and everything seems to be fine. i think this lappy needs to be blown out at least once a month or so . hope this helps some. - tommie j

Nope, you're not alone out there, posts are also made at the Toshiba Forum but no decent reply.
They reeally should recall these machines : people are now tinkering with the notebook, thus voiding the warrantee, but also since the machine gets so hot, it is waiting for an accident to happen.

>> old toshiba bios for satellite 1805? any body got one?
i reciently purchased a used toshiba satellite 1805 notebook that appears to be suffering from controversial cpu throttling.

i understand that early version of this bios did not contain this cpu throttle, and will allow my notebook to run at the advertised clock speed.

did anybody happen to save a copy of the old bios when upgrading? could sombody make my a backup of an early bios? say version 1.1->1.5?

thanks in advance for any help.

>> Toshiba Satellite 1800 Auto Power Shutdown
Hi, I've got a Toshiba S1800-400, which doesn't automatically power shutdown, but constantly just has the screen go black, which if you close the lid and open it again comes back visible. It can come back visible again for up to 10 mins or it can go black again straight away. Anyone got any ideas??
