Change serial number on IdeaCentre 730

2021-01-13, 1:10 AM

Hi,

A new client dropped off a 730 and asked me to clean it up and put on antivirus.  I did so, called, and then he said "By the way, the touchscreen doesn't work and I don't think the webcam does either."

Uh oh.

No, neither works.  And, the serial number doesn't show up in the BIOS, and there's a POST warning it's invalid.  After calling him back and asking where he got this unit, he said "from Lenovo" (sure), and he "thinks" someone worked on it.  "Did he put in a new Motherboard" I asked. "Yes, I think so.  I'm not sure".

So.

Is there any utility that can change the serial number in the BIOS?  I haven't been able to find one for this model.  Also, touchscreen doesn't work in One Key, doesn't show up (at all) in Device Manager, I already re-installed all the drivers and software - I'm thinking whoever "fixed" this didn't bother attaching the webcam or the touch screen cable.

 

Any assistance would be appreciated.

 

- Russ

Welcome to the community.

 

At least for ThinkPads, and maybe most all Lenovo PCs, the utility to write MTM, serial number, and other unique info to the BIOS, is restricted to the service depot and authorized service partners.

 

Regards.

That's terrible!  What possible justification can be given for that?

 

Well, I'll give him the bad news. I think Lenovo just lost a future repeat customer.

 

Thanks for the response.

For what it's worth I was able to fix that on a Lenovo AIO (A940) but I can't promise that the same steps apply to your device. Check here: https://support.lenovo.com/do/en/solutions/ht501039 but again no promises that this is the correct fix for that 730
