Lenovo's shipping BIOS error, causes USB to disconnect when keys pressed
The original BIOS that came with my Lenovo 3000 N100 causes my USB device to disconnect if any key is pressed. I solved the problem by upgrading to the newest BIOS.
Upgrading the BIOS to the latest version is not easy on this Lenovo 3000 N100 notebook. In order to load the latest BIOS version, you must first make an intermediate BIOS upgrade with an older BIOS version.
