Hi there, Looks like a rather minor dent. There shouldn’t be any damage to the battery and no need to worry. Although if you want to be sure you can unscrew the bottom of your MacBook to see if there are any dents in the battery. MacBook Pro 13インチ Unibody Mid 2009のハードドライブの交換

Hi there, this spot you are seeing in your photos is probably due to some damage on the camera lens camera or the glass over the camera. Have a look to see if you can see any marks on the lens. I actually noticed I have a similar problem with my iPhone 7, although like yours it is very minor. Also do try to update the software to avoid and variables. You should be able to update to IOS 14.4

Hi all. I found a fix! It was not malware or any such. So if you every accidentally reset Windows from the Windows boot camp it will install a non-boot camp version of Windows so you won’t have any of the options to switch between the operating systems but I found a way to get back to Mac OS. In Windows open settings and search for “boot” Then press advanced boot and then press restart. Once your into the advance boot there should be a few options to chose from, one of which is booting from a USB. Select that and make sure you have no USBs plugged in. There should be a drive with no name just an icon. Select that one and then hit enter and in my case that booted me right back into Mac OS. Seems like it was a back door into Mac OS. Hopefully this helps anyone else! On the boot camp I was running Windows 10 and on my Mac I was running Catalina and my computer is a 2019 27” iMac

Hi. Check this iFixit posting: Does not turn on Your device should still be under warranty. If it’s not it should only be out of warranty for a few months and you should be able to request an exception from Apple. Let me know how you get on.

Hi. What type of hard drive have you installed? I would take it apart again and put everything back to how it was before you put the new HDD in and check to see if it works then. If it does it may be a problem with the HDD that the computer is detecting.
