I am trying to make improvement to Aspire 4530 DSDT
The following is done using the Thermal Control Values from Aspire 4535G because I didn't hear overheated 4535Gs
I feel that this DSDT mod is good but I hope you get your feedback before incorporating the changes into BIOS release.
Please try this especially Gamers!
The aim is to reduce temperature during gaming!
