On start up of my Toshiba Satellite L505-S5990 laptop I get the error code F3-F100-0003. What does that mean? How do I fix?

Try removing the coin cell battery from the mother board for about 30 minutes. This resets the BIOS on a lot of laptops.

This website explains it well, along with a few options to fix it. Uses some computer jargon but is fairly easy to understand.

Hi,
Changing boot sequence.
Go to bios setting, click "F2" upon start up( when you read the bios and HD readout ). Choose the part boot sequence, click " enter" and choose what drive will be use first.
Save the settings upon exit.

Hope FixYa helped you out!

control panel ,,and do a system restore,,go back in time should fix it,,

locate the jumpers for reseting the BIOS with hardware... beware all settings on CMOS would be restored to default factory settings and password will be erased. Jumpers would be on the mobo near the proc/ near the memory modules/ near the edge etc...learn to use the jumpers from manuals for ur model of laptop...cos each model varies in the location and use of jumpers

If you want it free, you may have to download a copy of windows from a torrent site like isoHUNT, then download your drivers from toshiba.
If you download the same version of windows that was installed, you may be able to use the COA windows key on your laptop

Hello,

Please restart the computer and repeatedly tap the F8 key (you need to press F8 before windows starts to load)

A menu should appear. Select Safe Mode and press Enter

Let me know if it able to start in safe mode


Thanks

Take some time to polish-up your resume', since any company that is telling you to "downgrade" is a Neanderthalic place to work, especially if they cannot supply you with the "correct" (in their limited vision) tools (namely a laptop running XP) to enable you to work for them.


Some computers have "designed for Vista" or "designed for Windows 7" decals. This means that the manufacturer will not create device-drivers for the hardware inside the computer for the "older" versions of Windows.

So, you may need to purchase an external USB WI-FI adapter,
which will be sold with a CD-ROM that has device-drivers for Windows XP, and install the drivers, then connect the USB device.
