Hacking IBM Thinkpad Bios Password







This article is based on a IBM ThinkPad T42. There are no guarantees and you might end up destroying your TP. So continue at your own risk. Other models this ought to work with are:
240, 240x
390E, 390x
570, 570E
600e, 600X
770Z
A20m, A21e, A21m, a22m, A30p, A31, A31p
G40, G41
R30, R31, R32, R40, R50, R51
Transnote, T20, T21, T22, T30, T40, T40p, T41, T42, T42p
X20, X21, X22, X23, X24, X30, X31, X40, X41
The supervisor (SVP) password is stored in a chip called ATMEL 24RF08.It can not be reset by disconnecting the BIOS battery or shorting any jumper. It has to be read in order to deciffer the password. For this we need some kind of hardware so read on…
Soldering the ATMEL 24RF08 Chip reader
To read this chip we need to interface with it using a secondary computer and some simple electronics. You will need to purchase this:

2 x 2200 Ohm Resistors
2 x C5V1 Zener diodes (For example BZX55/C5V1 )
Serial Port 9 pin Female
The serial port can be salvaged from any old PS2 type mouse. The zeners and resistors can be found in scrap electronics, but they are rather cheap so i would not bother. Solder them according to the image below. Leave the wires leading to SDA , SCL and GND. These will be connected to the TP later.
Here is a simplified schematic for those unfamilliar with the above symbols:
Locating the ATMEL chip
Usually the ATMEL chip is located somewhere below the touchpad. Start off by remving the keyboard and mousepad. This is done by unscrewing a couple of screws located under the TP. It is quite clearly illustrated on the bottom side of your ThinkPad.
Pull the TP keyboard up and let it rest against the screen. Pry off the touchpad part and fold it over where the keyboard used to be. Remove the WiFi card.
Under it all you should find a chip with something like this printed:
ATMEL
24RFC8
0446
Heres a closeup of the Atmel chip. Click to enlarge.

You can see the Atmel right under were the Wifi card used to sit:

Soldering the ThinkPad
Now this is the tricky part. You will have to solder 3 wires to the motherboard of your TP. Two wires to the ATMEL chip and one to ground. The ground is a piece of cake, just solder it anywhere you can find ground. The mounting screw holes on the motherboard is a good place. Solder 3 wires according to the image below:
As you can see, the SCL and SDA are located right next to eachother. It can be difficult to hold them in place while soldering. I have used some tape to hold them in place. The tape can be left there to minimze the risk of pulling off the soldered wires during the next steps.
Leave these wires unconnected and make them ready by peeling off the insulation. These will be connected to the reader ciruit later on. Make sure they can not reach ground or short circuit in any way.
Preparing the spare PC
You have made the hardware to read the chip, so now you need to supply the software. There is this great sofware made by http://www.allservice.ro/ that can be found here:
http://home.ripway.com/2005-7/365678/index.htm - Select R24RF08 v2.0b - Reader for ATMEL 24RF08 (Freeware)
While you are at it, download the Supervisor Password decoder IBM Pass 2.0 Lite found here:
http://home.ripway.com/2005-7/365678/index.htm
Also great software made available by http://www.allservice.ro/ .
Note:
Softpedix wrote that the download mirror has limited bandwidth. If you can’t download with the above, try these:http://www.allservice.ro/forum/viewtopic.php?t=61 – Programmerhttp://www.allservice.ro/forum/viewtopic.php?t=56 – IBMpass Lite
Install the software.
Connect the ATMEL chip reader to the spare PC.
Fire up a command promt(Start->run type cmd) and navigate to the folder where you installed R24RF08 v2.0b. Type in (don’t hit Enter):
r24rf08 dump.bin
Dumping the password
Turn on your ThinkPad with all the wiring you just soldered.
Press F1 during the startup to enter the BIOS.
Wait untill all activity stops, blinking HDD leds and such.
Connect the ATMEL Chip reader. GND first then the SDA and SCL.
Now go to your spare PC and Hit enter on the command prompt.
Now there should be a file created in the same folder with the name dump.bin. Disconnect all the wiring off your TP and assemble it back together.
Decoding the Supervisor Password
On your Spare PC start the program IBM Pass 2.0 Lite. Load the file you just created (dump.bin). Navigate with the scroll list to the memory address of 0×330. Tada! It should look something like this: (see pics above)


Ive already done these procedures and works excellent.

HP Color LaserJet and LaserJet Series Printers - Printer Beeps

HP Color LaserJet and LaserJet Series Printers - Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector
Problems or issues may arise when an HP Color LaserJet or LaserJet series printer is connected to an uninterruptible power supply (UPS), a power strip, or a surge protector.
SOLUTION:
Plug the printer directly into a wall outlet to test. The surge protector or UPS may not be allowing sufficient voltage through to the printer.
CAUSE:
During the printing process, the level of current passing through the UPS, surge protector, or power strip fluctuates slightly, causing an inadequate supply of power to the printer. The following are common symptoms:
High pitched squealing, beeping sounds, or alarms (UPS)
NOTE: Noise over the phone line can also cause high-pitched squeals and beeping sounds.
Inexplicable or false error messages
Printer will not “wake up“ from sleep mode
Printer appears to be DOA
Incorrect printout
Slower than normal printing
The printer control panel display is blank or shows garbled characters
Accessories, such as attached copier/scanners, do not function properly
Monitor loses power or shuts off
Computer reboots when job is printing
Job only prints half way, causing a paper jam
SUMMARY:
If it is necessary for the product to be connected to the above-mentioned devices, consider the following items:
There are many UPS configurations and load conditions that can affect proper printer operation. Depending on these configurations or load conditions, printer functionality cannot be predicted.
No damage to current HP LaserJet products will occur, but, depending on their particular UPS configuration, the printer may or may not operate properly.
Printing while on a UPS battery backup is not recommended because of the large power requirements of HP LaserJet products.
If the HP LaserJet printer is not operating properly and power line conditions are suspected, try a different circuit (a different wall plug located away from the current one), or try removing it from the UPS.

SYMPTOMS
When you start Windows Internet Explorer 7, your home page does not open. Instead, a blank Web page is displayed.Additionally, you may receive an error message that resembles the following:
Line 56 Char:2 Error: Element not foundCode: 0URL:http://runonce.msn.com/runonce2aspx This problem typically occurs after you install Internet Explorer 7, after you install Windows, or after you reset Internet Explorer settings. This problem may occur only for certain users.
Back to the top
CAUSE
This problem occurs if the Customize Your Settings Web page in Internet Explorer 7 is not loaded correctly or if the Customize Your Settings Web page opens with restricted security settings.
Back to the top
RESOLUTION
To resolve this problem, create and run a Skiprunonce.reg file for each user account that experiences the problem. To do this, follow these steps:
1.
Start a text editor, such as Notepad.
2.
Copy the following information, paste it into the text editor, and then save the file as Skiprunonce.reg:Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main]
"RunOnceHasShown"=dword:00000001
"RunOnceComplete"=dword:00000001
3.
Exit the text editor.
4.
Double-click the Skiprunonce.reg file that you created in step 2. Now when users run the .reg file, they receive the following message:
Are you sure you want to add the information in path of .reg file to the registry?If the user clicks Yes, the user receives the following message:
Information in path of .reg file has been successfully entered into the registry.Notes

In Windows Vista, when non-administrator users try to run SkipRunOnce.reg they are prompted for an administrator password.

To run SkipRunOnce.reg for all users at the same time, an administrator can modify [HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main] instead of [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main] in the SkipRunOnce.reg file.
