Most recently I restored the OS (Windows XP) from the restore disk and after a couple of days of using the notebook it didn't recognize my finger swipe. Therefore, I decided I had to find a solution to this. I ran a search on google trying to find a fix for this issue, lo and behold this was a known bug in the BIOS in some Toshiba laptops. With doing a cold start, when the BIOS password is not set, some settings in the BIOS gets corrupted and sets a password. The articles I read suggested to short circuit the CMOS_CLR1. Although I located CMOS_CLR1 on the circuit board, I wasn't sure which pins I had to short circuit since I had no visual guide and I didn't want anything nasty to happen to my laptop. After some researching around and contemplating I managed to figure out what needs to be done.
First make sure the power cable and the battery is removed. Open the memory compartment at the bottom and take out the memory module. What you see below is the memory compartment cover removed and the memory module in place, which needs to be removed. There's a clamp at either end which holds the memory module in place. You just need to push them little outward and the memory module should lift it self up.
Then lift up the black insulation and you should be able to spot the text CMOS_CLR1 on the circuit board. Do not put too much force when lifting the black plastic insulation or it may tear. Just above the CMOS_CLR1 mark you should be able to spot something which looks like a zipper. Hold a screwdriver or something metal on that zipper like imprint on the circuit board for 15-30 seconds. Then put everything back together and you should be good to go. When you boot it will prompt saying the time has not been set. You can hit F1 to go with default settings or F2 to go to the BIOS setup. I selected F2 and set the BIOS password with something I will remember.

Excellent!!!
Thank you for this! The photos really helped. It worked the first time for me, on a clinic work computer. Our IT guy was impressed :)
You are awsome.good job
I used this BIOS reset on a Satellite M105-S3041. It worked perfectly. Total time was approx 4 minutes. Toshiba quoted $378 to address the same issue. Thanks
When putting screwdriver to the circuit board should I plug it in or put the battery back in?
gracias me funciono al 100
Plugging it in or putting the battery back either should be fine. I would go with putting the battery back on, cause anyway I'd need the battery.
Slick! My neighbor is rolling again!!! Thanks for sharing the love!
thanks very much..... is work 100%
Thanks man, it is december 2016...
Will give this laptop to my daughters with linux installed. (Learning)
You are a saver pal!.
Thanks :)
Funcionou. Obrigado!!!!!
I have a slightly different model Satellite M105-S3041. But I found the same zipper like solder just like you described here.
I tried to method and it doesn't work. Is it because different model requires different procedure? What am I missing?
Looking through some others comments, seems that it has worked on that model. Try holding on to the zipper little longer.

Useful information in 2022! Regards.
Thank You Very Much. I have two M105's, and had already dismantled one and was thinking to desolder one contact of the CMOS battery in order to reset the BIOS... and then, ¡miracle! you came to the rescue. One of 5he laptops already resetted. The dismantled one will follow.
My mom has this laptop and she passed 4 years ago. She had one password her whole life and this laptop probably hasn’t been turned on for 10 years. This is the only solution that worked. Thank you so much!
Gracias
I bought the m105-SP381, May 2024 and the BIOS prompted the password when typing F2. Thank you so much for this!
