See OH Smeg's TR posting of 1 June'08

The CMOS chip has been replaced by an [i]electrolytic capacitor[/i] called a [i]Smart Socket[/i] which does not require a trickle current to keep its memory intact.

So check your laptop's User Guide. If there is no CMOS battery illustrated or described, it probably doesn't exist.

The SmartSocket is NVSRAM.

But you are correct in that newer laptops do not depend on a CMOS battery to maintain the power-on password security.

These same laptops often DO use a supercapacitor (electrolytic cap) in place of some sort of RTC (real-time-clock) battery, as the clock does need power to function.

TR does not help with password recovery.

While it's entirely possible that your dog set your power-on password while you were asleep, it's also entirely possible that you broke the right-rear window of a blue 2007 Toyota Camry with a spring-loaded center punch and ran off like a scared bunny with somebody's laptop in hand.

I was a bit dense with this query - the purpose for the post didn't register. I'll be wiser next time...

Thanks.

You're obviously new here. Being rude like that won't get you anywhere.

We get questions about bios password cracking several times a day, the majority give cock and bull stories about sudden power surges, their 3 year old daughter, or cosmic rays suddenly creating bios passwords. So your's isn't new.

If you're the owner of the machine then contact Toshiba, they will be able to help you if you can provide proof of ownership.

If you've tried a battery that's a higher ampage than the one should be using then you may have fried your motherboard anyway.

Perhaps you thought there was more than one?

What make and model of computer does your dog have?

I'm thinking of getting one for Velcro, my cat. :D

You will have to take your laptop to a Toshiba service shop/agent to get it changed. Unless you like taking your computer to pieces and you are good with a soldering iron.

Please post back if you have any more problems or questions.
If this information is useful, please mark as helpful. Thanks.

You need to return this to a Authorized Toshiba Service Agent and have then clear the Password.
