![]() ![]() So I squirted it with a tiny amount of WD-40. That really only left the shaft of the fan to blame. I looked at the plastic fins, hoping to see an imbalance there, but they seemed ok. I next tried putting some electrical tape between the fan plate and the metal holder thingy, but that didn't improve things at all. The left side fan doesn't vibrate at all. All of the noise had gone away, but there was still some vibration. I went further still, and removed the silver plate that you had removed too, and ran the machine again. Doing that helped prove that the fan was vibrating within itself, and not just vibrating when in place. When I got into the fan area I decided to be even more bold than you had been, and I ran my machine with the fan removed, but still connected. Having changed the internal drive I was already familiar with all the screws to undo. It sounded so dire that I thought my hard drive was dying, and so I've upgraded the 200GB drive to a 500GB, and retired the existing drive to an external enclosure. I've had the dreaded noise for a little while, only mine was from, it turns out, the right side fan. Well, your wallet won't laugh so much, but you will. ![]() But you're going to laugh at how I solved the noise problem. The downside is that the temperature goes up to 30 degrees Celcius while the OEM and iFixit batteries go up to 27 degrees Celcius.Firstly, thanks so much for this page, it set me off in the right direction. It takes around 4-5 hours to charge the battery from 0 to 100% and I haven’t experienced any sleep wake issues yet.Īnother interesting point about the battery is that it’s design capacity is 7800 mAh, much higher than that of the OEM and iFixit batteries. I ordered a replacement battery from and it seems to be working as expected. While I’ve had a good experience with iFixit most of the time, it didn’t work out well this time. Unfortunately, the second battery kept charging very slowly and faced issues similar to those of the first replacement battery, e.g. I will update this question in about a month and will report the 0-100% charging time. Then, I get the following error from the OS when it turns on:īy disabling the deep sleep mode, the issue goes away.īased on Dan’s answer, during the SMC adjustment period, it is perfectly normal for the battery to be charged in 10 hours or so. I have to press the power button to turn it on. With the iFixit batteries, my MBP does not wake up from a deep sleep. Here is a screenshot from coconutBattery. That battery was charging very slowly too, but it had other issues and I had to request a replacement. This new battery is a replacement battery for another battery I received from iFixit a week ago. I was wondering if anyone has ever faced a similar issue and can give me pointers to what I should further investigate. In this case, I suspect the issue is not with any of the two. Therefore, people had suggested changing the adapter or the logic board may help. I have seen a few similar posts on the forum but not many of them had this level of detail in them. ![]() Here are some other things I have tried to address this issue: When I put my machine under a more CPU-intensive workload, the total “DC In” power becomes around 75W so I assume there are no issues with the adapter (I have also cleaned the MagSafe port to ensure there are no issues there). Therefore, there is room for the charging circuitry to draw more power (85W - 17W = 68W). According to iStat Menus, the “System Total” power is around 17W (because I am using an external display). The power gradually decreases as the state of charge increases. According to coconutBattery, the battery is charged with about 40 Watts of power when it is closer to 0%. ![]() The issue is that it takes a really long time to charge the battery (e.g. I calibrated the battery as soon as I received it and it has a couple of cycles on it now. The battery was manufactured fairly recently (about 165 days ago). I recently ordered a replacement battery for my MBP from iFixit. I have a 15” 2011 MacBook Pro which runs macOS Catalina 10.15.7 (I have replaced the logic board with that of a 2012 model). ![]()
