MacBook 6.1 very slow after battery removal.

crwdns2934249:0crwdne2934249:0:

Hello, I tried to revive my macbook 6.1 lately but I did notice a bump in battery that prevented touchpad from clicking, so I removed it to work it from the wall.
But while I was trying to update to the latest OSX, I did noticed the performance was horrible, I found out the kernel_task was going like 700% CPU usage in activity monitor and after some digging around that means the laptop is throttling.
I checked my temps they are fine (used ol good istat pro) so I couldn't figure out the problem, and then someone on reddit suggested to check the thermal sensor in the battery, which honestly didn;t even knew existed.
I will try to check once I'm back at office although the system is so slow that it is a pain to do that.
In the meantime I wanted to ask, if let's say the removed with the battery sensor indeed is giving some crazy readings, is there a way to stop the system from trying to read from it?
THank you!

+
+@danj Hey so as I love fire hazards I decided to go MacGyver and open up the old battery, and removed the module that was getting a bit fat.
+
+Soldered the 2 ends to close the circuit and installed it again on the macbook.
+
+So far it is working, the system reports weird numbers on capacity but the temp is good (sensor working), no burning smell, no hot spots on hand. Well I guess it somehow works.
+
+Given the way I'm planing to use this system I don't expect it to have any trouble and not catch it immediately. I will monitor it for sure but this is just an old system that I play around with, I will probably try to hack sonoma on it and then again reinstall OSX 10.6 to keep as vintage system around (the last OSX to have rosseta).
+
+Thanks for your input!
+
+edit: not that the mac performs normally I was able to look a bit more around with the opencore legacy patcher, to my surprise there is an option to disable through the installer the firmware check for the battery!
+
+So if everything went ok and I'm able to install a newer macOS I could also have the battery removed again to be safe from my tampering.
