MacBook Pro intermittently won't start with fan running strongly
Running Apple Hardware Test turns up error message 4HDD/11/40000000:SATA(0,0)
SATA cable (on your advice) and hard drive were replaced (with SSD) recently. Running Sierra.
After running the AHT (associated with the fan running strongly and the strip behind the keyboard being hot) the computer then boots ok. This appeared to fix things once before, the other time I have no idea why it resumed working normally.
When the device is down it will not run Disk Utility or safe boot. Running fsck did not help. Resetting NVRAM no help.
Your assistance would again be much appreciated

Just to be sure here: The AHT error was before you replaced the drive & SATA cable? Or, are you having this problem now?
Is this a single drive system (HDD or SSD in the main drive bay)? No other drive is present internally.

Thanks for your reply Dan
The new SATA cable and SSD drive were installed in May this year.
The problem has arisen over the past month
This is a single drive system. No other internal drive.
