Go to your laptop, restart it and press F1 key to boot to the BIOS entry screen again, and then try with the list of passwords one by one.

Good thing too as the customer has not come in yet to pick up their laptop!
Thanks all! That's all that happens and then it returns to normal. Lovely day for a Guinness! And pigs CAN fly! I have tried it many times and still the same result. Could anyone point me in the right direction? Thanks George. Since HMD is proprietary software, we are not allowed to give any further info than what is already available on this forum.

According to HMM, it should be on the left side of Looking to buy a HDD cover for TTP owners will have subsequently discovered, to their absolute amazement, that the manufacturer of their beloved TP offers no economically viable solution. The manufacturer does not have a policy to help genuine legitimate owners out of this predicament without paying, in some cases more than the TP is worth, to replace for no sane or logical reason their perfect and fully functional System Board!

The answer is NO, these are all perfectly sane intelligent people.

That icon with the small number 1 it may be a small number 2 or 3 if you have more than one Hard Disk] means the HDP is set. It will cost you more to clear the HDP than a new reliable Hard disk with warranty is worth.
Ok, you removed the HD and you see yet another Password Prompt icon. If you have a ThinkPad that can boot even though it has a Supervisor Password set. The CMOS backup battery [small single cell lithium battery, usually yellow colour] must be disconnected. That error message is your confirmation of a successful POP removal. That is NOT a real error, it simply means that once you can go into BIOS setup you need to set the correct Date and Time, so it is not something that is of real concern, nothing is wrong, this is normal.
It means that with POP removed, you have now absolutely confirmed that you do indeed have a SVP set and you can now put the time and effort into removing or clearing it.

It is your choice as to how you make the actual connections. GND is available at almost any large metal part of the TP, such as the metal arms that hold Memory in place, or the heat sink or almost any metal part inside the TP.
Your KeyMaker has electrical contacts on both sides, you must ensure that no part of your KeyMaker USB board comes into contact with any conductive surfaces such as bare metal or bare wires. You should place down a piece of paper and place your KeyMaker USB on top of it in order to avoid any electrical contact which may damage your KeyMaker. There is no danger of receiving an electrical shock from your KeyMaker USB as the highest voltage anywhere on the board is 5 Volts which is a safe voltage to touch.
The same precautions apply to your ThinkPad when you are performing any operation and BEFORE your ThinkPad is switched ON, you must ensure that nothing can short out by coming into contact with other parts, you can use sheets of plastic or plain paper to make sure things remain electrically isolated.
Your KeyMaker board is a delicate piece of equipment, treat it with respect. Do NOT experiment or connect to anything if you are not certain you have the correct connection points identified. There are voltages much higher than 3. Read more on Safety Precautions here. This page is under construction, eventually [it is a fairly large task] it will have all TP models depicted.
If there is a particular TP Model you need, email me and I will put it up here. If you have better images than these that you would like to share, email me. Last updated on Monday, 12 December PM.
