Wheres the jumper to reset BIOS on Toshiba Satellite P850 motherboard

SIW2 · 17 Sep 2019

Hopefully someone will have had the same mobo and may have an idea. Nothing obvious in the screenshots as far as I can tell.

None of us here can see the pins. Look for 2 or 3 pins grouped in line together. There is probably a little jumper on at least one of them. If you can't find it and removing the battery doesn't work then you might have to contact the seller.

On Gumtree I have recently purchased from a local guy (who has now movedhouse, which I knew was happening he was living in Sheffield)

AND

If I could get back to the seller (Joeif you are reading this call round to the house) but anyway as I say I’mpositive Joe would supply the BIOS supervisor password.

Probably this schematic might help, please see attached.

Regarding three pins that's a negative.

Just a thought on what SIW2 wrote I am willing / could provide a video of the pesky motherboard, I wonder if that's down to the Moderators to allow this.
As HAVOC has been contributing to this thread maybe they might be able to shed some light on this.

Here is one thing I found.
Going to need a picture of close up around the battery. You can jumper these connections to clear the BIOS.

Well it looks like I may have moved a bit further on in my quest.
Shorting the two contacts JRST2001 by the battery looks like it had no effect whatsoever.

So reading on another website [Try turning off. Leave for just a few seconds then turn on and press F12 a few times while booting. A list of bootable devices should appear][2]
[Bollotom][2]

As seen here;
Toshiba satellite c850 laptop no bootable device please restart system - MoneySavingExpert.com Forums

The thing is it is now allowing me to Leave "secure boot enabled or do I disable "secure boot"
I have a Windows 7 OS in the DVD drive and a blank HDD ready to go.
Your thoughts please.
I don't want to do the wrong thing and then get back to square one

Disable secure boot. You won't be able to boot win7 if secure boot is enabled.

Win 7 also requires CSM so there should be a bios setting for enable csm or it is sometimes called Legacy boot

Thanks for that

I have now disabled secure boot and found CSM under the Advanced tab that is now set to CSM Boot

Do I now just click F10 ( save and exit ) and leave the Windows 7 installation disc in the DVD drive ready to install
The BIOS boot order now reads
DVD
HDD
etc etc

OR

Do I just shut down altogether and THEN switch on the machine as I would normally install a new OS

If you make any changes in bios settings, you need to save and exit (F10) for them to take effect.

If dvd is first in bios boot order, then it should boot from the dvd ( if there is bootable media in the dvd drive)
