Startup chime
-
Macbook A1398 - had repeating loop of startup chime with no actual boot. Just startup chime, then restart, start up chime, then restart, etc. I pulled the battery and cleared BIOS. It will now power up, fans on, CPU warming, but no startup chime and no boot. I reflashed the BIOS chip but the same thing happening. Where should I go from here?06-14-2023, 11:45 AM

Power supply is good, tested it on an exact same... -
Hi, I've just repaired acer nitro an515-55 with specs:
i7-10750h, rtx2060.
Laptop had damaged cpu and after replacement came back to life but i have weird problem with this machine.

Hi everyone.
Lenovo Thinkpad E14 Gen 3, stuck on the "To interrupt normal startup, press Enter" screen.
Found a lot of people with this issue, but with no definitive answer. Some people managed to get away accessing BIOS, going to Startup and turning off "Option Key Display". For me that only removed the interrupt normal start up message, leaving only the Lenovo logo.
Most people say hitting Enter does not work. It's true, if you wait a few seconds. But if you hit Enter right away you get the options to enter BIOS (which works), run diagnostics (goes to a... -
Hey guys, so i have here really strange board...
These steps needs to be done to get a chime board starts to load osx but freezes with no loading bar:
