Remove the hard drive and take a look at the controller board on the bottom side of the drive. If the battery is wet, wipe it clean with a soft cloth. The sooner you disconnect the battery after liquid spill, the better. Remove the bottom cover, disconnect and remove the battery. Make sure you have all necessary screwdrivers before you start: Phillips #0, Torx T6, Try-wing and Pentalobe P5 (if you are fixing a MacBook Air). Do not try to turn it on! It has to be disassembled for liquid damage inspection. VERY IMPORTANT: After you spilled something on your laptop turn it off right away.

In the following example I am working with a MacBook Pro 13-inch but all following steps will be the same for all MBPs. The moment when you block the air that are flowing it will cause the temperature to rise and the macbook choose the other graphic card that are working.Not all liquid spills can be repaired but if you do everything correctly there is a good chance to get your computer back to life. How? After you put your macbook on, the fan will always start rotating.

People said that this trigger your graphic card selection caused by the sensor that detect the heat of your mac (since we covered all the holes with blanket / jacket / put it on soft surface such as bed). You can turn it on again and retry the method above If you think it's not working after a lot of retries then turn off your mac by holding down the power button. Sometime it takes up to 10 times to open and cover your laptop again with jacket. Do this for about 30 second and then open your laptop, if the screen is not on yet repeat the step. I usually cover MacBook with blanket or jacket. Put your laptop on couch or bed (any soft surface to cover all the hole on the backside of the laptop).

The step is turn your macbook and make sure the keyboard backlight is on. All that happens is the laptop screen is not showing anything after the macbook chime sound heard. The keyboard backlight works fine, the capslock button works fine. So my HDMI port is not usable anymore, repair shop assuming it's my graphic card that cause this problem. Me myself have been living with this kind of solution from late 2017.

#Computer turns on but no display or keyboard how to
Thanks for all the advice in this thread, you're all lifesavers!ĭo you still have this problem? I found a video somewhere on youtube that shows how to at least turn your laptop on and backup all the data you need. Put it all back together, turned it on and BOOM! Screen turns on, everything back to normal! So relieved that I've fixed it! However, I gave it one last go except this time I disconnected the battery and the display cable and plugged them back in. Almost gave up at that point and was resigned to the fact that I'd have to take it to get repaired. Tried wiggling it a little and screwed the case back together and frustratingly it did nothing. Followed the guide posted above to open the case and located the display cable. I've never done this before so was a bit nervous but I ordered a screwdriver set from Amazon and waited a couple of days. Connected it to an external display and got nothing but then I tried booting it whilst pressing cmd + D and it worked on the external display, however it completely shut off as soon as I tried to log in.Įventually realised I was going to have to open the case to see if the display cable was damaged. I realised that I could log in and suddenly the keyboard and Apple logo lit up and the backlight was working so I figured there was something wrong with the screen. Tried tapping on the casing near the display cable and pushing the black bar in at the back of the laptop but it did nothing. Had a completely black screen - not even a backlight. Had the exact same problem as you after my MBP had fallen off the bed. What is the culprit here? Iris video card, Logic board, loose internal connector, or all of the above? Is the internal display issue and this issue related at all? Then, I must boot into safe mode to use the mac again! And the cycle repeats itself. use keyboard) EVERYTHING GOES BLACK AND TURNS OFF. Here's the question: When I boot normally in clamshell-closed mode, external monitor works perfectly. screen isn't working- that's not the discussion. Finally, I can use my external monitor! I can get into my mac and mirror displays, so that I can offload my data. mode, and output on external monitor! However, white progress boot bar hangs at 1/2way for 3.6 hours. "HDMI signal not detected." Okay, so I do the Googles, read the reddit, etc etc. Apple logo on the back lit up, backlight was obviously working, but ZERO display workings. Went to boot one day and *chime!* but no screen. A1502, purchased in March 2014, has suddenly created a pretty nasty problem.
