Hello guys,

on my MacBook Pro 13-inch Mid 2010 + 2+2GB ram

I changed from HDD(macOS Mountain Lion) to SSD(empty) and a new keyboard(not genuine),

after this process, I did a clean macOS upgraded from Mountain Lion to High Sierra, during the upgrade was some firmware upgrade and it showed some failing to upgrade for some battery reason(it should be more than 25% charged even if it was 100% charged ?!) but after trying a couple of times it did upgrade also the firmware. (battery is not genuine)

Since then, the MacBook started to Frozen time to time (from 5 mins to max 2 days before frozen) I noticed the mouse I can move for a while but none response from the GUI, the clicking doesn't work and even the keyboard, if I try to click after 2/3 mins show spinning wheel, after that the only option I have is to hold the power button.

Noticed when it frozen I can get the CapsLock button getting the led on/off, that work simultaneously when I can move the mouse, I think it stops working when the mouse also stop moving.

without luck still frozen after those tests:

SMC and NVRAM reset

force quit when it is frozen but it doesn't respond

try the old HDD

using external USB SSD disk to load macOS with the HD cable removed

Apple Hardware Test multiple time without any error found

Switch slot ram 2GB and tried different modules,

Remove the battery and charged only with the charger (status of the battery normal)

Unplugged the CDdrive and speaker

Test old keyboard

Dissemble apart a couple of time and back

Change with a new HD cable

Reinstalled new MacOS different version (10.12, 10.11)

Not sure what else can I test?

Is there a way to find any logs once it's frozen on the next boot?

Can you clarify if this " new keyboard(not genuine" is internal ?

When you say "Test old keyboard " what does this mean you pulled the "new" and re-installed the "old"

Have you tested any of this against a know working external keyboard...(?)

My first guess is the internal TrackPad/Keyboard cable is damaged.

These flat ribbon cables are actually not cables but flexible circuit boards, usually mylar, with printed circuit traces taking the place of wires. This type of cable can experience cracks in traces due to aging, heat, vibration, impact or abrasion. They can be damaged quite easily.
