sleo Posted July 25, 2023 Share Posted July 25, 2023 Hi, I have an unusual question. Well, I have broken the motherboard in my E5470 running Catalina on Clover 5119 and it looks like I will have to replace it (or buy a new laptop). So I'm wondering, if I buy the exact same model of motherboard and replace it, is there any chance that my system will boot? Or is there no way and I will have to reinstall everything?

Administrators Hervé Posted July 25, 2023 Administrators Share Posted July 25, 2023 As long as it's the same motherboard model (even with a different CPU if it's soldered provided you're not using a CPU-specific power management SSDT but the PlugIn method), all should work upon straight replacement and without any need to re-install macOS at all. Just make sure the replacement motherboard has same or latest BIOS version and adequate/same BIOS settings as the old one. 1 Link to comment Share on other sites More sharing options...
Jazzoo Posted July 25, 2023 Share Posted July 25, 2023 Absolutely! I did it with one of my Latitude 5450 and it worked without any problems. As @Hervé said no need to reinstall OS after that. Link to comment Share on other sites More sharing options...
sleo Posted July 25, 2023 Author Share Posted July 25, 2023 Dear @Hervé and @Jazzoo - thanks for the good news for me. Btw. do you think I could replace the MB myself or would it be better to have it serviced? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 25, 2023 Administrators Share Posted July 25, 2023 That's entirely up to you, we cannot guess your ability or not in that respect. You may simply follow the documentation available on Dell's support web site, it's not very difficult. Link to comment Share on other sites More sharing options...
