Hello,

I have a 2013 Macbook Pro 15. 10 seconds into the bootup the fans go full throttle, the MacBook is slow to boot, and once it does manage to boot the CPU is > 100% at all times.

• Ran AHT, it reported – 4SNS/1/40000000 TsOP—124
• Bought a new trackpad with cable, replaced. No change, same issue.
• Removed the logic board, cleaned everything and reinstalled. No change, same issue.

Any suggestions / help would be deeply appreciated. Thanks.
