Ushering in a new dimension of interactivity to the Mac, the new trackpad features built-in force sensors that allow you to click anywhere and haptic feedback that provides a responsive and uniform feel.
#2015 13 MACBOOK PRO UPGRADE#
Do that when you get it all sorted out.The 13-inch MacBook Pro (Early 2015) was introduced on March 9th, 2015 as an evolutionary performance upgrade to the 13-inch MacBook Pro family that also marked the debut of an all-new Force Touch trackpad. That said, I always recommend cleaning with an air duster and replacing the thermal paste (cheapest Apple could find) with some quality stuff. It will just be an exercise in futility.Ī "dirty" logic board won't affect function - it may contribute to heat issues, but it won't prevent it from booting. If it boots, there's a good chance it's the top case.Ĭleaning/removing the JTAG connector won't hurt, but it won't help anything either. Since you're limited on tools, if you can get it to boot again, go into System Preferences → Energy Saver → Schedule and set a wake time for about 10 mins into the future. It may be failing and the power button is non-functional. You may luck out and get a good logic board and given that you've got some electronic skills, part it out and recoup some funds.ĭon't rule out the top case! (Until you can, of course). Surf the secondhand market (eBay, Craigslist, LetGo, etc.) for a MacBook Pro of your vintage that is broken for some reason (LCD, battery, etc.). I've personally used his services (not affiliated, but very happy customer) and his pricing is roughly half of what it costs for a logic board replacement. There are very rare occasions to actually reset it (contrary to Apple diagnostic lore), but this is one: you have a bona fide power issue. The SMC is actually the PMU in every other laptop on the market. There's very little chance it's the DC-In board (connects) to MagSafe because a) it boots with battery not connected, and b) it's charging.
#2015 13 MACBOOK PRO FULL#
The moment you remove power coming from the battery side of things, your MacBook works (not at full performance, albeit). There's a rather large clue that the issue is the logic board:

I would hate to replace the logic board, but sending it for repair would be a similar cost to replacing it. I have removed and reseated the part the MagSafe connector, connects to (power module?). Issues before and after battery replacement have been somewhat intermittent in terms of power connector LED and CoconutBattery readings. Would like to remove the connector, but don't really have the equipment to do so, it is way smaller than the boards I used to rework for Seagate back in the early 90s. The motherboard is not dirty at all, it lives on my desk on a stand, except when on vacation, but thought I saw small bits of solder between legs on JTAG under microscope, used tweezers to clean. Watched Louis Rossmann video and cleaned out JTAG connector, booted normally, ONCE, after that, with full speed and good readings on CoconutBattery, (battery made in March 2020, 1 cycle).

Displayed the battery as made in 1979 at that time. Thought maybe battery went bad even though it only had 3xx cycles, so bought iFixit kit and replaced the battery. Opened the back, unplugged battery, can boot with battery disconnected while plugged into power, but runs slow due to no battery. Plugged it back in on its stand the next day and nothing happened when I pressed the power button. I know the bag didn't get too hot because my candy bars didn't melt :-). It worked fine prior to vacation, never used it while away, schlepped it in computer bag, only removed from bag at airport security on the way there, and again on the way back.
