                      So the error is not due to the bios.

                              I tried both files,

                              UC16M1 - 16MB - still get the same error messages about date and time, and SVP.
                              UC16M1 - 16MB_PATCHED - it hangs on Lenovo screen

                              Maybe because my board is REV:1.0., not sure.

                                Edit: On board itself I found sticker with this code: FRU 01LW020 and above is barcode PSL10N67045.

                                I'm not sure if this helps, bacause on device itself I do not have any sticker with serial number and type stated (I bought it that way secondhand).
                                Behind the battery is only P/N number ( P/N:SPP0M92510 ) that I mentioned in post before.

                                Can someone please help?

                                Thanks

                                        Hi AMATEURSAHIL, i already replaced the cmos battery and it still givese the same error. Also i made patched file that volinakis flashed it and it still gives the se errors. I managed to find somewhat cheap replacement board from ebay and it works fine for now. But this time i was smarter and backed up bios and saved serials and type numbers. Thanks everyone for the help.
