Hi, my mbp early 2011 don't boot without smc bypass. I reseted smc before but it dont turn on.
White light in front is flashing quickly when charger is plugged.
I tried to unplugged battery, i replaced it 6 month ago, but nothing too.
I see on the net it could be a hardware damage but which one ?
thanks

First, try resetting the NVRAM/PRAM - Reset NVRAM on your Mac - Apple Support
It's almost certainly hardware damage, though. The quick flashes of the status indicator light mean this. As for what kind of damage- it's hard to tell exactly, but if it's the logic board you will probably just want to buy a new computer. It likely is too old to be serviced anyway, but you could try - Obtaining service for your Apple product after an expired warranty - Apple Support
Also- this community is for Boot Camp-related issues (the software that allows the dual booting of Windows and Mac on the same Mac). A better place for this question would be the "Older Hardware" community.
If you reinstall macOS and the issue persists, it's a hardware issue. I highly recommend taking it in for service, or at least a check. It doesn't cost anything to get it evaluated.
I replaced magsafe module and hdd cable because it doesnt start and it shows folder question mark, i boot with sata x usb cable plugged in my hdd outside

You'll likely need to repair the startup disk with Disk Utility - How to repair a Mac disk with Disk Utility - Apple Support
Thanks.
NVRAM reset dont give anything, but i replaced by my old original apple battery and all work perfect. But it dont charge, i saw the charger's green led off and the info in the battery menu, now it's empty and im gone back in the same situation.
A difference, smc bypass boot dont work with this old original battery, i have to replace it by the newer to boot like that.
Do you think its software or hardware problem ?
