Mine is toshiba L505 es5015 it asks for current password and i dont know how it entered it. thank you.

Boot up or restart your Toshiba laptop.

Immediately and repeatedly tap the F2 key on your keyboard until the start screen appears to change your BIOS (user) and supervisor

(HDD user) passwords.

Use the arrow keys on your keyboard to highlight "Set User Password" or "Set HDD User Password" and press "Enter" on your keyboard.

Type the current password in the box that appears.

Type your new password ox.

You will be asked to enter your new password a second time to confirm it.

well,it's processor is Intel Pentium Processor T4400
and if i'm not wrong,it's already the best processor on it's socket family
for addition information,it's processor socket is Socket P

Does it have a battery? Removing for a few minutes seems to work, but keep in mind current BIOS setting might change.

Step 1Turn on your laptop. Press the "F2" key when the first loading screen appears. This will load the BIOS. You'll only have a second or two to press this key before Windows begins to boot. If you're not fast enough and the Windows screen comes up, simply restart and try again.
Step 2Use the right-arrow key to highlight the "Security" tab. This is the third tab from the right.
Step 3Press the down-arrow to enter the Security Settings menu. Scroll down to "User Password," listed beneath the "HDD/SSD Password Select." This will open a pop-up window with three text fields.
Step 4Type your current password into the "Current Password" field. Press "Enter." Type your new password into the "New Password" field and press "Enter." Type the same password again into the "Confirm New Password" field and press "Enter." The "Password" window will close.
Step 5Press the "F10" key to save your new settings and exit the BIOS. Your laptop will now boot normally.
TipHDD password can be changed as many times as necessary. However, once you enable password protection, you can never delete it.

Try ubuntu, you can find it at ubuntu.com just download it and burn it to a cd. It free and all of it apps are free too, also you can install it along side windows. If this dont work it maybe some fisical damage to your computer. You can also try to enter the toshiba website and downloads all the drivers for your current model.

As you describe your problem I can see that your laptop asks a bios password. Well you have to open the case of the laptop and locate a small circle battery, this is the bios battery. Eject this battery and the laptop's battery and unplug the power cord. Try 2-3 times to power up the laptop (without batteries or power supply, just for the capasitors to discharge). Wait 5 minutes. After that plug in again the bios battery, the main battery and the power supply. Start up your laptop. Just before Windows logo comes up hit del (or F2) repeatly in order to get in to bios settings. Find the command "load bios default" and hit enter. Adjust the date and time and any other settings you wish (boot order e.t.c.). Save the changes and reboot. As you can see you are ready.

In case of a problem or clarification, don't hesitate to post me a reply.

1.You either know the BIOS password or you don't . this will require a tech to reset the password entry to default so that you can access the laptop. this is done at the mother board level usually
2. Contact the manufacturer and speak with tech support to walk you through a password reset for the BIOS.

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
