    Thanks for your suggestions but I've already tried all this with no satisfactory result, apparently a lot of people who own Advent and E-Systems notebooks have the same problem it was a vista update that has corrupted the bios and as yet there is no fix! I really need someone with and E-Systems 4115C Notebook to make a copy of their BIOS so I can flash mine with it and hopefully fix!

Follow these steps & ur issue might get resolved(80% chances):
turn off ur notebook-->take out the laptop battery(not the cmos battery)-->disconnect the charger if its connected to the notebook-->now press & hold the power key for atleast 20 seconds, remember that u have to press & hold the power key & dont release the power key till 20 seconds are over--> & ensure that the notebook is not connected to any power source while u r performing this step niether the battery nor the charger--> also there shouldn't be any peripherals connected to the notebook-->once 20 seconds are over & u have released the power key-->connect the battery & the charger back to the notebook & now try to turn on the notebook-->u might not get a blank screen & ur issue might get resolved, turn off ur notebook again & restart to ensure that its not reoccuring....(This whole step is known as power drain & it is done to remove the extra static electricity which sometimes get stored in the notebook & gives a blank screen in return.)

In the top left of the screen appears a padlock, apparently requests a password or something like that, I can unlock it? Thank you

Your machine has a Supervisor password enabled. It is usualy the last 4 digits of the serial no of the laptop. If that doesn't work then the other thing you can try is to remove the BIOS battery and reset the BIOS.

You will need to open up your laptop. The laptop CMOS battery is shown below.
Disconnect it for 15-30 minutes or more, then reinsert it and the data in the BIOS memory should be reset. If at first it doesn't work, try to remove the battery overnight. Once the battery has been reinserted power up the PC and see if the reset was successful.

Bios password crack

Remove a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings.

Under the keyboard or bottom of laptop - If you are working on a laptop computerthe location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

If it fails, then try to remove the battery for at least one hour.

hope this helps

Cmos reset

I have not specifically worked on this make/model of computer.

Technically, you cannot reset this ... I think what you are asking is how can your modify the settings. Typically one would press F2 or F8 or F11 to enter the setup during the boot process. It may be a different F key, it should flash on the screen when you boot.

You could disconnect the battery back up if you can locate it. ..This will remove any custom setting, but will not let you get back in to change it unless you find the correct F key to press.

On the other hand ... there are no more than 12 F keys. You should be able to find the proper one.

If this doesn't work, you should go to for assistance.

To reset the bios password on your laptop, you will need to remove the cmos battery on your laptop for some minutes and insert back, the cmos battery is located on the motherboard of your laptop, once the cmos battery is removed from the motherboard for some minutes, the bios password will be reset, and that fix the problem.

Actually you can clear the BIOS password by resetting the CMOS jamper. If you are familiar with CMOS jamper it is easy for you. Open your laptop with the use of screw driver. Once you are already open it locate the CMOS jamper near the CMOS battery at the south bridge of your laptop motherboard. Remove the jamper with in 5 seconds after that reinsert and trun on your laptop.

Foget the bios password

To reset a bios password you need to remove the CMOS battery in the laptop. Here is a link to the manula from the Thinkpad T20:

If you have some technical knowledge then you can try the following procedure. If not then I would recommend leaving the laptop into a professional to do this instead. 

First off go to page 66 of that manual. You should see a picture of the battery pack on the bottom of the laptop being removed.Make sure that the A/C adapter is unplugged from the laptop. First slide the switch indicated by the number 1 in the drawing and then lift up the battery. 

On page 67 you should see a smaller battery being removed (which is the CMOS battery we are looking for). First remove the screw indicated by the number 1. Then, gently lift out the piece as shown in the bubble with number 2. 

After 10 seconds then reinsert the CMOS battery and screw it in again. Then reinsert the battery pack and start the laptop. The bios should be reset and the password should be removed. Any settings that were stored in the bios will be reset to their defaults. Unless you have changed these settings before then they were probably at their defaults anyway.

I hope this can help,
