Toshiba A135-S2276 Bios Reset

By japfingsten ·
I just bought a Toshiba A135-S2276 to take with me to Iraq. Well, I've had it less than a month. I plugged in something to the USB drive, it froze up, so I forced restarted it and at the Bios screen it asked me for a password. I've researched the heck out of resetting bios passwords and all, and I'm running out of options. I definately never set a password for bios, this I know. The defaults don't work. Since mailing it back really isn't an option at the time, I took it apart down to the motherboard. The CMOS battery is soldered on. I can't find a jumper or dipswitch anywhere. Anyone have any help, advice, or expirience on this particular model and can offer me their two cents. Thanks alot.

"Power unit off. Disconnect AC power. Remove battery..... ...Short solder JOPEN1 solder pads for 30 seconds."

Pardon me but don't you need power to create a short?

When you disconnect the battery and the AC from the laptop, how do you think it keeps the correct time?

Regardless of power, a short is just a condition which represents a path for current.

Quite so, dear boy - and you said it!

What do you reckon, based on your ob(li)vious techy stance, would be the effect of a thirty-second short on a rechargeable battery?

What state of charge would it contain after such a procedure?

What ability to retain a charge would it then possess?

Would it still function as a battery?

Or is there a risk that the electrolyte might just happen to go for a walk?

It won't harm it any. Most devices use a cap instead of a battery, because it's cheaper and does not need to be replaced every three years

Shorting the pad to ground basically removes the bios battery from the circuit, allowing the eeprom to clear. The Bios battery helps keep the data in the eeprom. If the battery ever dies, the eeprom again will clear.

You're supposed to read the post - not just the TITLE !..

by OldER Mycroft In reply to Battery

The guy wasn't interested in 'shorting out / clearing out' the EEPROM.

He was asking how to get rid of the BIOS password.

As you should already be aware, the password is no longer stored in the EEPROM, so shorting out or denial of battery power will achieve nothing other than a reset EEPROM.

Also, had you taken the time to notice WHEN the question (that you never read) was posted, you'd have realised the OP has probably retired from active service by now, let alone returned from his tour of duty!!

That (thankfully) I've never heard about.

How else do these folk find all these ancient artefacts that once were active threads ??

Maybe because they're just THREADS they get mistaken for artefacts

All we need now is an "Indiana Jones" avatar! :^0

They're actually quite easy to resurrect...........

If one uses any of the major search engines on a regular basis, they'll notice that TR posts come up quite often. All you have to do is click on the link and you're taken directly to the article/forum. You may land in the middle of a thread though, so often people will reply to some old thread and, after registering, actually resurrect the thread with their own new post.
