Question Toshiba satellite p75-a7200

[jrslexus]

Toshiba satellite P75-a7200 specs:
Processor: Intel (R) Core(TM) i7-4700MQ CPU @ 2.40GHz
Ram: 24.0 gb
System type: 64-bit operating system x64-based processor
Windows 10 ver 21H1

I can access the bios by pressing F2 when the laptop is booting up. Once in the bios, the keyboard doesn't work and nothing can be changed. The only way I can make any changes is to remove the CMOS battery for a minute; restart the computer, enter the bios and the keyboard works fine while in the bios. Is this unique to Toshiba P75?

Thank you in advance for your thoughts / suggestions.

Welcome to the forums, newcomer!

You might want to shut down the laptop, disconnect the battery from the unit as well as the power from the wall, then remove the CMOS battery for a good 30 minutes, then press and hold the power button on the laptop for 30 seconds and then replace the CMOS battery. Once replaced, power the laptop using the power adapter and then let the OS boot to GUI. Speaking of GUI, what OS are you working with? What sort of changes are you inputting in BIOS?

On that note, what BIOS version are you currently on? Might want to use the serial number for your laptop on Toshiba's support site and see if you have any BIOS updates pending.

Lutfij:

Your questions are answered as follows:

Operating System: Windows 10 Home
Bios Version: 1.60 (this is the most current version via Toshiba)
Changes to BIOS: Don't want to make any changes; just wanted to be sure I could access the bios in case issues were to arise requiring changes. Spent time on the internet reading and researching and gambled on temporarily removing the CMOS battery which worked and let me access the bios. Prior to that; I could access the bios but couldn't make any changes from the keyboard.

I am currently in the process of performing the following steps you recommended:
Disconnected power from wall
Removed laptop battery
Removed CMOS battery

Once I wait the 30 minutes; I'll complete your instructions and see if I can access the bios without having to remove the CMOS battery.

Your timely response to my initial question is most appreciated.

After approximately 30 minutes, I put the laptop battery back in, held the power button for 30 seconds, replaced CMOS battery and plugged in the power adapter. Powered up computer; it booted to the GUI. I waited about 20 minutes and attempted to enter the BIOS using the normal process of booting and pressing F2. Got into the bios and as per my original message; and the keyboard wasn't functioning. I had to remove the cmos battery, wait a minute, put the battery back in order to change the date and time.

I can only presume this must be a "unique" characteristic to this Toshiba laptop.
