Late 2011 MBPro sudden and repeated restarts

[Giuanniello]

Long story short,

my late 2011 15" MBPro is one of those Apple had to repair under warranty, got a new mainboard and since then run smoothly, it's an i7 with 16GB and 1TB SSD, runs way well for my needs (somehow strangely it seems faster at converting videos than my 2014 16GB 1TBSSD Mini...) but it's a couple months or so that, all of a sudden, under no particular circumstance or, say, CPU or disk load that it restarts like several times before it becomes again usable.

I was suggested battery might be responsible, it sure is old (9 years!!!), do you think it might fix the issue by changing it for a new one?

Grazie

Sounds like RadeonGate.
Look that up if you don't know what it means.

There's no "fix" any more.
You can change out the mainboard, but it's got the same problems and will fail again (as yours has).

Best option:
Get something else.

The mainboard has been changed due to the faulty video board, the issue I have now doesn't seem to be the same, back then I could tell there was a failure in the video board with video artifacts on screen, now it just reboots with no warnings or malfunction, just reboot...

By the way, also my poor iMac 27" late 2009 has a dead Radeon :-(

Does the MacBook have any logs that may provide an idea as to the cause?

 

[Giuanniello]

I have no clue, I can try and get a print screen when it restarts as to show you the on screen message but I have no idea where the system logs might be

Rossman to the rescue

Could be a team up problem too. Try using it with only 1 stick of RAM.

I read here on the forums that the sudden reboot might be due to an old battery, now it's almost two days it is running smooth, the battery indicator in the status bar shows 96% charge, the mag safe connector led is green but an app I downloaded to check battery status gives the following stats, is it possible then the battery giving such issues?

Just thinking, might it be the thermal paste off the cpu which needs being replaced? Bad heat dissipating? Is it hard to remove the heatsink off the cpu?
