Toshiba Laptop Not Retaining BIOS

2

We have a Toshiba Satellite L50-C-1FR laptop.

For some reason, one day it stopped retaining all the BIOS information (time, date, etc). The info has to be set every time it's booted. The first thing we thought was to change the CMOS battery but this model doesn't have a CMOS battery.

Also, it appears to have no pins or jumpers for a reset.

We replaced the laptop battery, the charger, the memory, the hard drive, reinstalling the OS and changing the OS but none of these replacements worked. We even tried using the replacememnts in various combinations with the original parts but this didn't work either.

We've pulled our communal hair out trying to figure this out. Can this be sorted, if so, how or do we now own a Toshiba laptop doorstop?

Did you replace the CMOS battery (image for reference)? It's not clear from your question

2Ah, "battery" might not be "CMOS battery" but might be "laptop battery". Good call, @CaldeiraG. – Arjan – 2019-10-24T09:59:54.247

@Arjan that's what first popped out of my mind :) – CaldeiraG – 2019-10-24T10:00:46.000

1Have you moved the jumper for a CMOS reset, and left it on the wrong pins? – spikey_richie – 2019-10-24T10:04:22.683

Would anyone know if the CMOS battery is typically also used to preserve the settings? (Rather than only for the real-time clock.) – Arjan – 2019-10-24T10:09:00.883

2@Arjan typically yes – CaldeiraG – 2019-10-24T10:12:34.657

Hi all. Edited the question as suggested to add relevant detail. Thanks all. – MartySmartyPants – 2019-10-24T14:05:52.723

Looking at some pictures of your computer MB, it seems it's a jumper somewhere I didn't find yet. I'll have a look later :) – CaldeiraG – 2019-10-24T14:07:23.517
