Question: Slow CPU usage has spiked Task_kernel is using most of my processing power.

My computer went from working great to all of a sudden running slow and with fan full on, mouse lag, keyboard lag etc. Anyone know how to fix this? Here are my is my etrecheck if this helps. I did not notice it being correlated to any new hardware or software. My daughter spilled a few drops of orange juice on it near the bottom and charging port but they cleaned it off right away and nothing appears wet or corroded on the outside. Any ideas? Thanks folks!

Performance: Poor

Problem: Computer is too slow


My CPU usage % has gone haywire. The Kernel_task is using 490.6 of the available CPU. The fan runs all the time and I have keyboard and mouse lag. Apps aren’t working correctly, seems like they just beachball or lag.

Its possible but I'm 80 % sure it's not based on the description of the spill. The juice spilled close by and the only thing that it could have been is a few stray drips. Is there any diagnostics I could run to look for damage?
