Laptop not booting. Chime sounds broken
Hi,
My macbook pro non-retina 2012 gets stuck at the apple logo progress bar.
On boot, there is the chime but it doesn't sound smooth. Has a vibration to the chime sound.
For a few weeks, I had noticed screen flickering but the laptop used to boot. Now it just hangs at the progress bar and screen flickers on and off with colors.
Some technicians diagnosed it as logic board failure. My questions are:
1) How can I decisively say its logic board failure? The technicians say they are not sure. Since diagnostics for logic board is not completing, they assume its the logic board.
2) Is it advisable to replace logic board or should I simply get a new laptop?
Thanks for the help.
