Hello

I have a 410 and... I disassembled it, retraced the rtc and suspend to ram battery traces and assembled it and it works fine, except for the fact that I have an extra part, and I cannot figure out where it belongs, it's solid and not a flimsy cover.

And the second issue, it sounds like very high pitch, happens after BIOS with and without Har drive

Note: the service manual is "incomplete" as it does not show step by step

Please see attached, thank you
