something interesting...

[elohelomg]

So, someone brought in their computer today, saying they put a bios password on it. now, the easiest way is to remove the cmos battery, so, i opened the laptop up, and, to my surprise, there was a cmos battery, or at least i thought that was it. the battery is really small, and is soldered on the mobo. so i took it apart, waited for 5 mins, soldering it back on, and it still didn't reset the bios.

Jumpers.. I never like even thinking about resetting using jumpers... ( and I would look for DETAILED instructions ) but that is the only other way I know of besides using other tools. ( which I have never seen actually work.. Like boot disc utilities... )

[WaKa WaKa]

Some laptops dont reset the bios even with clear CMOS. If you take out the battery, and wait 1 day.... NATHING HAPPENS. The password stay there.  :angry:

I think they put the password in a non volatile memory.

[shought]

A picture of it's MoBo could help ;)

[HX1]

Yeah it would.. maybe..

Did you try any of the Hiren's Tools? You are talking about BIOS Pass not DriveLock or Hardware Lockout?

[LeetPirate]

Is it toshiba? Well you said a computer but some reason I assume laptop cuz that's where you mainly find soldered cmos batteries these days. You don't need to remove the battery, look for a tiny jumper called J1 most likely. On a laptop it's usually a pinless jumper with just a pair of bare copper contacts exposed, most often it looks like 2 interlocking capital E. You short that jumper and the bios will reset.

I remember those idiots at Toshiba love to password protect the laptop bios and they don't tell you about how to reset the bios in their documentation. Anyway look for a jumper, that's your best bet.

Lots of times those jumper pads are under the memory if a laptop. Pull out all the memory dimms, you may need to peel up a plastic cover sheet or sticker to expose the PCB and look for what LeetPirate said. Might help if you gave us what brand and model it is.

This may sound silly but, I had this issue a few years ago with a computer I was working on. Now, I had trie everything I could think of to reset the BIOS to default and nothing was working. Knowing that pulling the battery should do the trick but, also you cant run the PC with the battery out. Back then, they didn't have jumpers.

So, what I did, and to my amazement, it worked was, Take a business card and slide it under the battery, between the battery and the mobo. So that the PC will run but the battery won't make it remember. Leave it run for a few mins. I let it go like 20 minutes then, shut it down, pull out the card and boot into the BIOS. You should then be able to reset to default if it isn't already there.

Good luck!

Sorry guys, i've been away all day.

Its a toSHITba (i hate em as of right now) model number ls505d.

Can you please post a bigger picture of the jumper, as i cant seem to find it.

@DocBob1939

Which batter? The main batter that powers the computer, or the cmos battery?

[BookCase]

@DocBob1939

The CMOS battery. (Flat, Round, Silver battery)

Just a heads up, the battery is soldered on there. you sure?

I have completely removed the battery as well, with no avail.

On toshitba laptops open the cover by the memory module area and look around by the expansion slots, it should be right next to the expansion slot area. Between the expansion slot area and the memory slots, you should not need to remove anything to see it. I really dont have a picture or anything but it is a tiny copper interlocking E shaped conductor flat on the board itself. It is tiny so you need to look very carefully, trust me sometimes I look a few times and never see it but after a while I find it and wonder how I could not see it before. It's the only thing that looks like that and should be labelled J1. All you have to do is touch it across with a flat head screw driver, don't scrape it or anything just a light touch does the trick because the copper is bare and will conduct well enough with a mere touch with a flat screw driver tip. Use a flashlight to help you find the jumper.

I wouldn't go breaking anything unless I owned it.

To reset the password of a Toshiba, you can use KeyDisk.

Stuff like that, looks like this from above:

[LeetPirate]

Nah those are desktop jumpers, the laptop ones are mainly flat traces of copper on the board. they don't project out of the board. Did a google search for the images, these came up.

[shought]

Whoopsy, my bad :P (Never reset a laptop's BIOS before...)

[HX1]

That is freaking tiny... Probably what mine looks like..

I cannot for the life of me, see the jacks.

@DocBob1939

The laptop does not have a floppy drive.

@dcs18

I would gladly run hirens cd, problem is, the computer wont boot. You cannot boot into a cd, you cannot do anything, without the password.

[HX1]

You know that was something I always wondered about.. some of the tools we have available are actually useless...LOL

[NoJuan]

Did you try Flashing the BIOS with one from the Toshiba Site and see if that resets the Password ?

You will have to use whatever BIOS recovery method applies to that particular Laptop to do it.

If that doesn't work then the Password is probably stored on a sparate chip and can only be reset by reprogramming that Specific chip.

Hirens has a great tutorial for putting the .ISO on a flash/pen drive. Perhaps you could try that.

I bet if you disconnected the HDD and ran a USB Boot it would work.

Worth a shot.

UBCD used to work wonders. Has a Boot and Nuke to nuke the BIOS. Not sure if that's still around or not.

I ended up flashing the bios, and all is well now. Somehow, that removed the password O.o

Thanks guys :D
