MacBook Pro wont turn on Your computer will not boot. RAM issues If your computer beeps three times, there is a RAM issue. Either you have insufficient RAM to boot, or the RAM you do have is faulty. First, access the RAM slots (Core Duo or Core 2 Duo) and ensure you have RAM installed. If you have two chips, first reseat them and try again. If that doesnt work, try one chip at a time to see if one of the chips prevents the machine from booting. If none of these work, you may have a bad logic board.neeed to replace the logic board or need to replace the memory controller chip on the logic board. Bad Left I/O Board If your left I/O board is bad, you will not be able to start your computer when its plugged into the wall. It may or may not run on battery and the light on the power adapter will not light up at all (some power adapters do not have lights, so this may not apply to your computer). These symptoms point to a left I/O board that needs to be replaced (Core Duo or Core 2 Duo). We carry replacements for the following left I/O boards: Core Duo, 2.16/2.33 GHz Core 2 Duo, and 2.2/2.4 GHz Core 2 Duo. Bad power adapter If your battery is not charged, is completely dead or is removed from your machine, please make sure you are NOT using a 60W MacBook Magsafe adapter! A MacBook Pro is shipped from the factory with a 85W adapter and needs the full 85W to boot. The 60W adapter will keep a charged battery from draining but does not have enough juice to provide full charging functionality. If your power adapter is bad, the computer will run off a battery, but it wont charge. If your batterys charge is too low, it will be difficult to diagnose a bad power adapter. The easiest way to test this is to borrow either a battery or power adapter to test in your machine. If you have the same problem with another power adapter, your problem is most likely the left I/O board. If you have the same problem with a fully charged battery, you most likely need a new logic board. Thermal Sensor Issues If the fans run at high RPMs, but the computer does not boot, there is probably an issue with the thermal sensors. First, ensure that the thermal sensors are plugged in. If they are, try replacing the thermal sensors. If this does not fix the problem, the logic board most likely needs to be replaced or fixed Bad logic board If replacing the DC & sound card and battery dont fix your problem, replace (Core Duo or Core 2 Duo) the logic board. We offer the following logic boards: 1.83 GHz Core Duo, 2 GHz Core Duo, 2.16 GHz Core Duo, 2.16 GHz Core 2 Duo, 2.2 GHz Core 2 Duo, 2.33 GHz Core 2 Duo, and 2.4 GHz Core 2 Duo (SR). if your logic boards damaged seriously,need to replaced,we can provide you the original one with good price.if not seriously,we can fix it,we can find out the root cause,only replace the damaged chip on the logic board,that will help you save much money!
