Hi there. I recently upgraded my 2012, 13-inch MBP. I installed a 1TB Samsung SSD and 16GB of ram. My machine is much faster and works just fine. My only concern is probably a minor one. Whenever I open my MBP from sleep mode, the startup chime plays. This never used to happen before the part upgrades. Sometimes when its closed the chime will randomly play too. May you please shed some light as to why this happens and how to prevent it? Thank you.
