13" macbook pro takes 20 to 30 seconds on everything action

OK figured it out😁, the computer had Sierra installed on it since I owned it, in the course of all that the apple update gave it new SMC files and Boot rom...the SMC file dealt with battery issues. That lead to a search where I looked up the latest boot rom and SMC for Sierra and High Sierra .

. The SSD is an Samsung that was a cheap replacement for my older SSD, OWC said its going to fail, replace. Thus I loaded a small ssd with the install disk for High Sierra , and loaded it onto the 750 HDD data drive, and it installed like it should, AND matched the boot rom and SMC on the computer. The battery issue stopped, and the SSBO is completely gone..hooray

Thanks Leroy and CT!! you guys were very helpful.

I'll try the the hardware test, when I hold the D key it goes to internet recovery so I'll start it up and do the AHT. In AHT test extended test..will reply back in 1hour or so after I get results.

1. yes it happens on a second account setup as admin, it takes a while to set it up at 30 secs per movement or action.
2. As I said it also occurs in safe mode, SSBOD just like in normal mode. I'll double check after the AHT.

Third party software isn't installed this is happening in a perfectly clean install, zero apps installed except a clean load of El Capitan. Installing EtreCheck will be a pain, after I double check safe mode again, and AHT, I'll take the time it takes to install it and then print to file the results so I can post them

I've done 20 hours of trouble testing, been using Macs for 16 years, linux for 22, so I'm adept at OS X...thanks for the help so much.

oh I should add I've reset PRAM / NVRAM and done a SMC Reset...these had zero effect, afterwards each action still takes 20 to 30 seconds.. for every click, or any action. The problem persists in safe mode as well.

its a brand new Samsung ssd which is in perfect shape, the symptoms occur with a internal ssd and both an external ssd or hdd..I have begun to think its hardware related, as disk utility reported every drive used internal or external was in prefect shape.

Leroy,

its a early 2011 MacBook Pro 2.3 GHZ with 16 gb OWC memory, MacBook 8.1, El Capitan installed, Samsung 860 QVO 1TB SSD (MZ-76Q1T0B/AM) V-NAND, SATA 6Gb/s - primary channel, Seagate Momentus® XT 750 GB SSHD in secondary channel (as data drive), with owc data doubler try installed.

Previously it had a 500GB Samsung SSD and a 500 GB Momentus® XT 500 GB SSHD installed as a fusion drive, moved to a 1TB SSD to improve performance. All was running fine, when suddenly all **** broke loose and the computer started running in Granny slow it takes literally 30 secs for any action to get the SSBOD to stop give a mouse curser (sp?) , and then every step after 30 sec each. To Install a second admin account took 10 to 15 min.

So very slow to trouble shoot. However it ran for years as a fusion setup, was running fine with this SSD installed.

I'm calling OWC one the cable will let you know what they say. I had wondered if a cable got squeezed and had an intermittent slight short??. I'm running the AHT, which will take a while.. 1.5 hours so far for the extended test... I'll post those results later.

All I appreciate your help.

Ok both the short and extended AHT test gave the same result:

4XXX/4/40000005 "Battery"

I'm assuming I need another oem battery..I'm thinking the battery was replaced by a friend, as he'd bought it from me, and he used an off brand..non-oem battery. what do you guys think? I'm just surprised I have the SSBOD issues while its plugged into the wall on a power supply
