If WIndows is installed, try opening an elevated Command Prompt (filename: CMD.EXE) and issuing the following commands:
wmic.exe baseboard get product wmic.exe bios get name,serialnumber,version wmic.exe csproduct get vendor,name,identifyingnumber
Do any of them return a serial number?

It sounds like someone sold you an engineering sample or a pre-release version. That is consistant with the manufacture date. - 15/09. (YY/MM) That was earlier than final versions were being made. I think the seller should have told you that when you bought it.

Drivers and support files for the P50s can be found at
Even if it turns out that you have a pre-release or engineering sample model, many of these drivers may still work on that model.

Yes, I know that. In fact, I installed the current Win 7 install myself from a standard CD (with USB3 drivers from Lenovo slipstreamed in). Most of the drivers do seem to work fine, as does the system in general. But there are a few niggaling issues. In particular:
1. There are still 3 "unknown" devices in device manager, even though I think that I installed all of the drivers.
2. I can't seem to install Win 7 SP1, as it gets to 11% on the reboot configuration and then rolls back. This is most likely a missing device problem.
3. Although the Intel video driver is installed and is reported as working correctly, the installer failed, and the Intel video control panel crashes whenever an option is selected. That control panel dll also reports a crash on every new login.
If I had a serial number that worked, than TVUS would be a great way of fixing (or at least checking) these. But TVUS starts the scan and then reports that TVUS can't update to the latest version (in fact, the latest version is already installed, as is MS .Net 4.5). I suspect that it isn't sure of the model and type for serial number reasons.
So I have a system which is about 95% working, including sound, hotkeys, Fn keys, video resolution and trackpoint/pad. But, as an IT Pro, that last 5% is bothering me.

For the unknown devices, what are the Hardware IDs listed for them in the Device Manager? Maybe determining the correct drivers for thos will resolve the issues with Service Pack 1 installation and the Intel video driver issue.
