1) Locate and remove the RTC battery

2) locate and remove the main battery and unplug power supply.

3) depress the power button for 30-60 seconds.

you do not have to solder anything to the board if there are posts ic 61,63 on MAIN PCB then just put a jumper across them while you power up. if its just 2 SMD pads just use a needle probe to arc the connection.

for a better result remove the battery for about 5 minutes, because sometimes it needs more time :)


don't forget to hold the power button down for 60 seconds and remove the main battery as well.


Remove the BIOS battery for more than two hours and the problem still exists..


Removed the cmos battery, removed the main battery, left it for about 18 hours. No results. I pulled the batteries and shorted the pins while holding the power switch for 60 seconds. Still didn't help at all. Then I tried every combination of shorting, unplugging, and turning on that I could think of. Still have the problem....


does the the problem above has been resolved??

you should always call panasonic tech support at panasonic headquarters for the proper way to remove bios lock. there are different ways to do it. if you dont do it properly you could do damage . i damaged the cmos socket just by removing the battery…its a good thing i’m skilled at soldering. I was able to re-solder the cmos posts to the board and i put a drop of epoxy between the cmos socket and the reset socket next to it in order to bridge them together so that it wouldnt happen again
