Wifi not working and fana going very fast. I've tried almost eveything
Hello, I am dealing with very strange issues. My macbook started to behave in very strange way. It all began at the day I have took it from repair. There was flex cable changed and mainboard lighting chip replaced.
That day, last friday it started to have strange lags which were only on battery, not during charging. I deleted only a .plist file and it worked fine for few hours.
After few hours it started to drop wifi and fans were going so hard (over 6000 rpm)
Wifi works fine only after boot, for about 20 minutes and ther there is no connection. Wifi is on but system info is telling me that it is off. I don't really know what to do now. I am really confused because of that situation. Before it was everything working well.
Thank you in advance
There is WiFi on but if I check system report it shows that WiFi is off. I can't guess what is happening here, and it makes me so nervous, just because I can't work online what is quite important to me.
There is also another problem
When I run geekbench it showed me that showed me
~1500 pts single core
~1504 pts multi core
The first one is normal, but second should be around 2100 as I got while I was running it before giving it to repair after short circuit
Reinstalling system did not change anything. The problem returns
Reseting SMC and PRAM also doesn't work
I also written a message on facebook to the place where they repaired my mac
I mounted a disk caddy instead super drive and my macbook started to work as before. I have faulty hdd connector. I realised that voltage on battery is to low so at certain moment system was going crazy in order to avoid short curcuit. Now everything works fine!
Is this a good question?
