Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Thanks Markus,

Am i right that both 4mb files in the zip are identical to both 4mb in my rar? Ie both the original (obviously) and the patched.
So i do not need to reflash the 4mb file.

The changes i see are to the 8mb file? And there seem to be quite a lot of changes within.
so from what you have given me id only need to flash the 8mb/64bit chip ?...

Re: components from schematics what are they and how to find matching alternatives.

thank you RJ.

. Could somebody please give me some pointers. I'm trying to fix my lenovo laptop. i have the schematics but im finding it hard to source components or get data sheets.

and
LTC015EMFS8T2L

Any pointers that would assist in working out from the product code what the spec of the component...
