[Friph]

Hi,
Last night i turned off my macbook,but today when i tried to turn it on,it wont
No light,no fan sound,nothing...
(I already tried the 10 seconds trick with/without battery)
(I already took the ram out,change the ram slot and etc)
(I already put the ram into other Macbook pro and the rams are ok)
nothing worked,
What can be the problem?

Battery dead? As in your battery could’ve gone through so many cycles it won’t recgarge anymore and could need to be replaced.

Bring it into a repair shop, it’s a little too hard to help you with something online with little information and a sudden problem. You could also have a dead logic board. Sorry, can’t help much online

This forum is for the Mac Pro desktop.

You might have better luck asking in the MacBook Pro laptop forum https://forums.macrumors.com/forums/macbook-pro.90/ .

assuming your using an 85W charger

and the machine is completely dead

then quite likely Capacitor C7771 on the logic-board went bad, when it does it pulls a main voltage rail to ground causing the machine to become a potato/ie not boot up or do anything at all, its a relatively common issue with the 2008-2009 MCP79 based 15 and 17 inch MBPs...

if you replace C7771 then the machine will boot up again.
