MacBook Pro 15" CPU LOAD OVER 90~100%
Sorry I’m from Hong Kong and my English skills are very low
I just bought a second hand MacBook Pro 15” 2011 Late i7 2.2 GHz from a Facebook user.
Sadly, I found a problem with it. The system has a terrible lag, asked the seller immediately and he said he don’t know and was just helping his friend to sell it then he blocked me for any further dialog!
I google searched looking for more information on this condition. Most of the results and instruction to try to fix the issue nothing helped. Here’s one link thats like my systems problem: https://discussions.apple.com/thread/822...
Okay let’s back to help me.
1: CPU Load OVER 90%~100% when use 5~10 mins
2: When CPU OVERLOAD is on, EVERYTHING SLOW. But if I close the MacBook up about 30 secs then open it back, CPU Load is back to Normal, but 5~10 mins passed, it will back.
3: Computer fix shop found my Battery is not Original
My MacBook is at the computer shop now and they tried to fix it about 1 week and they still have no idea. They changed my Original HDD to SSD, installed the newest MacOS, Changed the RAM, they found my Battery is not Original and it’s new! 5 Cycle count, they didn’t have an original battery to change it for test, so they think the Battery is not the point make the computer lag and they fully checked my MacBook only the Battery is not Original everything is Original works well.
(Also the discussions apple link the last answer is Direct BATTERY is not ORIGINAL)
[I tried to find his friend 2weeks and I writing this post he replied he changed the battery and upgraded the macOS to HIGH SIEERA in same time then he found this lag problem too so he wanna sold fast]
4: Keep CHARGING , CPU Load keep in Normal
Keep Charging with 85W Apple Original Power Plug everything is well , but if I remove the power charge, CPU Load will Over 90% IMMEDIATELY
5: Reset SMC, PRAM, & Safe Boot didn’t help anything
Please help.Thanks
(I told the computer shop worker some repair problem I can’t do like:
1: Try to replace the Trackpad sensor {I found this from: Fan running at full speed, CPU throtled}
But I don’t sure because the Fan is normal.
2: Try to downgrade to El Captain

I have same issued and now already solved it, Its caused by battery, mostly found in demo laptop at showroom, because long term plug in cause battery malfunction, Circle count may low like new but battery is already gone. I change the new battery and fixed it. Now still I using this MacBook Pro 15" have no problem.

I think it may be the battery as per the previous comments BUT ALSO.... I thin you make also have to replace the Thermal Paste on the CPU as CPU Overload is due to your machine also running very hot and a MacBook pro are nearly 5 to 8 Years old now so I would highly recommend getting the thermal past redone as I have seen MacBook pro Laptop straight away improve their performances. All the best I hope this works too
