[SOLVED]820-2936-B still running slow after fixing sensor issue

[PhilipC]

Fixed the p-bus voltage sensor issue and the machine now passes ASD.

But it's still running slow, mouse moves fine but click on anything and it takes 5mins to come up.

Tried reset PRAM and checked HDD health

This machine was liquid damaged, original problem was the sensor issue and the IC's for LSHIFT and OPTION keys

 

[arghhh]

Bad hard drive cable or hard drive.

First boot from a good USB. If still slow then run the OS ASD test and see if it comes up with an error the EFI ASD didn't catch. Also make sure battery is good, swap for another one to make sure.

Replacing battery did the trick. Didn't know they could affect the performance. Thanks
