Toshiba Satellite C50-B-14D Will Not Start or Go into BIOS!

Hardware

Got an unusual problem on my desk

Client came in with a toshiba laptop saying windows would not accept her password, could i get her data off. No problem. Boot to linux mint plug in an external drive, mountain the windows drive and ignore the security windows sets.

Copied all the files off so she went away happy. But left me the laptop to put mint on to it.

Booted to bios but said date time error, so set to correct time and date, thought change cmos battery tomorrow.

Installed lmde, rebooted everything worked fine.

Took it apart to replace the cmos, and could not find a battery, no cr2032, no battery in a plastic cover with fly leads. Nothing indicating a battery. Been through the mother board and no Marks. Checked the web site and no clues on any strip down vidéo looks like it could be on the board but no idea where.

Worse still will not boot now, cannot get to bios no matter what keys I press. Tried esc, f2, f10, f12, tab all the usual. Tried external keyboard nothing.

Just shows the toshiba splash screen then sits and looks at me.

Tried with usb that had installed from, Tried a DVD with mint on.

Now searching my head as its empty, any ideas

Thanks

Hold down the [Esc] key and switch on the computer. If a corresponding prompt appears, release the button and press the [F1] button.

Thanks for the suggestion, sadly not change. No message just splash screen. The keyboard is working as the num light comes on.

I would pull the laptop battery and hold the start button and reset the laptop!!! Try then and start the laptop with just the charging cable, if it starts, shutdown and install the battery. I had a Dell like that, and come to find out it had a defective battery!!!

Try a different power supply ac adaptor. They do tend to play up and cause strange problems.

Did you also try FN+F2? Some systems have FN-lock configured by default so that thos keys behave volume up/down etc. In that case FN+F2 is the real F2.

Once you got in the bios, you can change that setting.

My final idea, at least for now, is to completely reset the BIOS data. Some machines have dedicated pins on the motherboard where you can create a short circuit.

Trouble with laptops is finding where on the motherboard to short as there are no clues like the CMOS is I guess a capacitor instead of a battery but no sites offer circuit diagrams

The trouble is, you’ll have to disassemble many devices from the laptop to uncover the CMOS battery. I think it is below a heat sink.

If it really has a cmos batt. at all?

Seems it lacks indeed:

Going to try keyboard removal tonight but suspect its a capacitor rather than a battery.

In the end it’s going back to the client for scrap.

Motherboard never got to bios no matter what I did

The hard disk I formatted and put her files back on the disk, but its showing as a bad disk and many sectors damaged

Plus the 2 memory banks 4 and 8 were not the same speed although the same fittings

Loads of hours wasted, but such is life.

Not quite a total loss. Your mental apparatus has been upgraded, and you entertained us for a week.
