Motherboard was replaced, bios shows invalid machine type and serial number invalid

I've read a few posts so far about how to fix it and what program to use. Well, I've tried the DMIEdit, but it's incompatible. I don't have the money to take it anywhere so I'm not sure what to do. I'm running a H50-55.

Re: Motherboard was replaced, bios shows invalid machine type and serial number invalid

Welcome to the Lenovo Community !

 

I'm not an owner of your model, but there are some BIOS update utilities that also offer the option of updating serial number and model number information on the motherboard.  In checking the available downloads for your H50-55 I see the BIOS update download also includes that flash utility.  I have never did such an update on your model so I would recommend you review the README instructions which can be found here......

Here is the download location for that BIOS update file and the included flash utility.....

Thanks for posting back.

 

When you updated the serial and model number information it sounds like the BIOS settings were then defaulted back to their factory set values which bypassed the graphics card.  Glad to hear you were able to resolve the issue.

 

Were you successful in updating the information you wanted?

Re: Motherboard was replaced, bios shows invalid machine type and serial number invalid

Hi!

 

I've the same problem on a G560.

Replaced motherboard, Invalid information in BIOS

 

How I watched, two of three USB ports not working and intel management engine interface can't starting in device manager.

My windows is working, but boot procedure is so slow. Machine fan works full speed at all time.

BIOS updated via Win7 from lenovo website.

 

Can I do something with it at home or I must to take it to a Laptop service?

 

Thx a lot!

Re: Motherboard was replaced, bios shows invalid machine type and serial number invalid

Redhanded, in reviewing the downloads for your model, the BIOS update utility lacks the necessary files in order to use it to update the serial and model number information.  That being the case, you will have to take it into a service center as they have the special software needed to update that information.

 

The service center would also be able to check over your replacement motherboard if the non-working USB ports, high speed fan and other issues are happening with that replacement.  The replacement could be defective.
