tomorrow I update the BIOS to latest version (2.58), after this operation my laptop can't boot: pressing the power-on button it displays only a black screen and the power-on led...
I've tried everything I can do to get it working, I was ready to call support for a warranty repair when I tried to remove the extra 4gb RAM: whitout it my laptop boots fine... I try to replace the module with another 4GB, which is new but without success.
So, after the bios update I can use my laptop only without extra RAM modules installed.. obiuvsly it works fine before.
Is a faulty motherboard\memory slot or there is something I can check? I need at least 8gb for my work...
thanks in advance

Hi, the system was originally shipped with 4GB RAM - 2x2GB 1066 - and there is no warning and the BIOS update is recommended by Lenovo Update application. BIOS update was performed successfully, but after upgrade, system is unable to boot.
BIOS downgrade is not supported -there is warning in readme file for this BIOS update - that no BIOS downgrade is possible.
In addition, thank you Lenovo for making my 4GB RAM not working anymore.
