MacBook Pro does not start

Hi I recently repaired an old Macbook pro late 2008 (macbook pro 5,1) an it worked fine

since tomorrow when i was testing the battery durability without the charger it worked well but if you overcharge it the computer shutdown but if you plug the charger back and press the power button it works. But tomorrow the computer shut down and now if I press the power button it does not start…

how can i resolve?

You didn’t say which kind of repairs you performed on that Mac, it may be useful to get an idea of what might have happened. Try running your Mac just off Magsafe, without battery in place to see if that works and rule out a possible battery failure. If that works the easiest attempt to fix the issue would be replacing the battery but be aware the problem may come from SMC and related rails too.

I have repaired the monitor and installed a new ssd

the computer does not start with the battery and without it

@polliog Try disconnecting all and everything from the board except magsafe, leave out the screen too and see if you may have a shorted part there and the board alone is still alive. If you have no signs of life something may have gone wrong on the board while performing your repairs.

@arbaman don't work the start up with the power pads

@polliog Sorry to hear that, if you have no signs of life shorting pads with other parts disconnected the board is virtually dead without a component level repair.

To force a spontaneous reboot, disconnect the battery and mag-safe. Press and hold the power button for 10 seconds. Reconnect the battery then the mag-safe and it should reboot.

Lets take a good look at that battery. Please run and post your results using Coconut Battery: https://www.coconut-flavour.com/coconutb...

That's a core2duo, doesn't boot on its own, needs power pads to be shorted.

@arbaman where are the power pads on this model?

@polliog There are several boards included within that Mac series, you'll have to pick your own..have a look at this page: http://www.insidemylaptop.com/turn-on-ma...
