I have an old Toshiba Satellite Pro ps610u-024k19 that has been sitting in closet for a couple years. There is a bios password on it. I don't remember putting one on it. Therefore i don't know what it is. How do I bypass it? I have taken it apart, removed what I believe to be the cmos battery. I also removed the proccessor. I put it all back together.....password is still there.

THE BIOS password must be blank or somebody else set it just hit enter and try if not the BIOS password should be reset. Regards, Mike

Just click on the lick below and follow the instructions:

Method 1 (Flash BIOS)
Flash BIOS for Satellite L300-ST2501
Flash BIOS for Satellite L300-ST3502

1. Remove the battery and don't turn on the laptop (a minimum of one day or more). To remove electric current, which is still stored in the laptop. Based on experience, can turn a normal laptop, try to enter windows.
2. Download Flash BIOS slb0v150.exe then open the file, select Install, and select Install from Windows - OK.
Flash BIOS can remove the BIOS password

With solder, remove the BIOS IC, wait about 10 seconds, then plug it back. To remove the BIOS IC, you must remove the screws down and the LCD.

I hope this information helpful.

Remove the laptop battery and unplug the ac adapter. Then remove the bios battery from motherboard. let sit for a couple of hours. this should do what you want to do.

There is usually a couple of pads underneath the laptop that will short out the BIOS battery which will reset the BIOS settings.

• Disconnect the AC and remove the battery
• Remove the memory
• Peel back the black plastic film underneath but don't remove it entirely
• Attach a piece of adhesive tape on the underside
  
• Insert a memory stick
• Stick the tape down on the case
  
• You now have access to the two shorting pads named B500
• Reconnect the AC and short out these pads.
  
• Power on the laptop with these pads shorted out until the Toshiba logo disappears
• Remove the AC and remove the memory stick
• Remove the tape and replace the black plastic film
• Reinstall all the memory
• Replace the battery and the AC

This should have wiped out the BIOS passwords. Use enter to get into the password protected areas.

Hi,
for removing the password,

you have to open the memory cover and remove the two RAM s,
after that remove a black or whit plastic film depending on your model, you will loacte for B500 marqued ( XXX ) or J1 you have at least short
the two point with a flat screwdriver and put the upper memory and power on the laptop will holding the screew driver till you see the toshiba screen, if it doen't work just try again. it works 100%

This is the ONLY other way, save paying Toshiba and filling in proof of ownership forms.
