2200 Machine Type And Serial Number Are Invalid Lenovo Support

. Download ThinkPad Hardware Maintenance Diskette (HMD). I have 1.83 attached here.

You can certainly find other versions on the Internet somewhere. DO NOT use windows 10!!

I've only tried windows 10 & 7, both 64 bit. Windows 7 worked with all my flash drives. But the application will not find your USB stick on windows 10. Unzip the TP HMD. Use 'usbfmtpw.exe' to make a bootable HMD USB. If it says 'Error: Drive not found to format', then it's very likely it can't run on your OS (Windows 10 for instance).

The numbers are shown in the BIOS (the Machine Type and Serial Number show 'INVALID', but other numbers are there). However, there is no option in the BIOS to change the numbers. I was able to obtain a Hardware Maintenance Diskette image for the Think branded Lenovo's (IBM's?), which is only supposed to be available to repair facilities.

Otherwise, you will see a format window. Make sure it's your flash drive. Don't worry about the size. You can always format it in windows, and the flash drive will turn back to normal. Boot your Thinkpad with the USB stick you just made.

You might need to hit 'F12' to open the boot options to choose it. You will see a blue screen with some descriptions of the tool. Choose option 1, '1. ' or something like that.

I can't remember now, but it's pretty straightforward once you are at this step. Follow the instructions. It's pretty easy.

You will need to input the Model Type and SN together, with '1S' at the beginning. Say, model type 1234CTO, SN 56789AB, you will need to input '1S1234CTO56789AB'.

It may vary depending on your machine. Then simply reboot.

Depands on how you view 8 On tablets and stuff.great On your main PC.rubbish! 7 is like all the best of XP, and the few best bits of Vista combined to a simple uncluttered stable great operating system.especially with heaps of RAM as I have Microsoft must secretly agree.they refunded my full purchase price of 8 and recommended a retailer to buy 7 from.which I did I know many won't agree, but I'm running four computers on 7.they're all fast, and it's great for me So, yeah, it's an upgrade Stu. On this Lenovo motherboard.unlike most others. Removing the Cmos battery does nothing.and there are no jumpers to short out to clear the bios password. They use a chip like a memory stick.it's good forever. Once it starts asking for the password there are only two choices Enter the password Replace the motherboard As I brought this machine 2nd hand I have no idea what the original technician who set it up used for the password or who he / she was. But the new motherboard and loads of RAM are all working like a runaway train I can live with it.just be nice to speed up bios by having the type and serial correctly entered and not having to go through the error thing Stu.

Hi Rider and OtheHill, You are the first guys to show me this possibility.Lenovo techs never mentioned it, and other online 'specialists' also agreed that the Lenovo board was a disaster My loss of $160.00 On the plus side, the machine is up and running like a plane falling from the sky, and I have deceided to live with the error message in bios.adds ten seconds to bootup.what the heck!! Thanks guys for your help.really appreciated from all in the forum. And I've learned heaps (a real bonus).and am happy to live with the result and consider the case closed As a last comment.I really regret the demise of the desktop (tower) computers that you could really get into and work on and fix Laptops, tablets and I thingys are throwaways.they work till they stop.then you bin them and buy another What a waste!
