My laptop doesn’t turn on after battery repair

I recently attempted and thought I had completed a battery repair on my MacBook. But when I flip it around and try to turn it on nothing happens. Then I connect it to power and the Apple logo comes on. Stays on for awhile then goes away and it hasn’t tried to do anything sense. I have gone through and made sure every connection is there and all the screws are in the right place I just don’t know what to do any help is much appreciated

Why did you replace the battery in the first place symptoms wise? Is it possible there was a deeper issue than the battery?

@axdog - Do be clear the system was working without any obvious problem, correct? Was the system conking out quickly half as long as what it should be.

The system worked completely fine and powered on and stayed on, I just wasn’t getting the powered on time that I wanted out of it

It sounds like the new battery may be faulty or not properly communicating with the system—try an SMC reset, double-check the battery connector, and if that fails, test with the old battery or a known-good one.
