ОтветыReseated RAM, blank screen, beeping every 5 secs. tried everything ...Your Logicboard can't read the RAMs. The Boot-EFI say it to you with the beeping. Just to make sure: are you using the same RAMs like you are using before? Try and unplug both RAM-chips again and plug then in (carefully). Make sure they are complete in. Usually the click in. Start your Mac. You don't have to make a SMC or VRAM reset. If your Mac doesn't turn on. You RAM chips are faulty and you need new ones. Maybe you touched them without ESD protection. Let me know if this was helpful
Ответыkeyboard qwerty line don't working wellYour MacBook needs a new Topcase with new keys. An Apple Service Provider can help you with that. Probably the previous owner droped some liquid on the keyboard or travelled somewhere with high humanity e.g. Thailand, Singapore...
ОтветыMacBook Pro 2009 won't turn onHave you checked the DC-In Board where the MagSafe Power Adapter connects? Check, if the connect-pins are ok or maybe clean that with alcohol pads. If you have a spare DC-In Board try to replace this and give it a test. If that doesn't work, then you have to start with the minimum configuration: - disconnect everything from the logic board except the fan and keep the DC-IN Board on the logic board - plugin the MagSafe (it should turn on the green LED) - then connect the power pads on the logic board and check if the fan turns on. If yes. The logic Board is ok. If not, then the logic board is faulty and has to be replaced. IMPORTANT: Please do everything with ESD Tools and use a ESD Anti Static Mat and Anti Static Wrist Strap!! Let me know if I could help you with this advice.
