Diagnostics returns with SMC-Problem, Reference Code PFM 006.

SMC reset attempts do not change anything. What can be done?

Dear Dan, No nothing spilled into the laptop and it did not drop or get banged. The worst that happened to it: it got transported several times in a padded back pack on planes and trains.

The story with the fan is lengthy. It started to act up last September but returned to normal after I stopped Drop Box to run all the time. Two weeks later the fan started up again for a month. One night 2/3 through backing up my home directory the fan stopped running again and everything seemed normal (when the fan is going full force start-up is very slow erratic, also the computer is very slow. Activity though is very low). Anyhow the fan then started to act up again about three weeks ago.

I wonder whether there is a fully temperature gauge.

i understand the ram in a macbook air is soldered. i would like to replace the 2 gig chips with 4 gig or even 8 gig, will the macbook air hardware recognize the additional memory?

if yes, other than warrenty issues; why would ifixit team not take a chance to un-solder the chips?

I use my laptop everyday because I am working on some papers despite having the battery swollen. I've already made a schedule to replace it next month but I'm wondering since I still need my laptop to do my work, is it safe to remove the battery and using it with the AC power only?

I'm afraid the battery will expand more and it could damage the hardware, so I want to remove the battery and using it directly to power cord.

Thank you.

"Mac OS 10.13 High Sierra (or later macOS) must be installed on the host computer before installing the Aura Pro X SSD. These versions included an EFI firmware update for your host computer. Without this update, your new Aura X Pro will not cunction once installed."

How do I update this so the computer can see the new drive? The old drive did not work so I am not sure how that would be an option.

I haven't found many details online but as far as I can tell all the other parts are the same so the boards should be interchangeable.

Judging from IFIXIT and some other online sources (same means identical or reported to be compatible):

• Bottom case: same
• Top case: same
• Battery: same
• I/O board: same
• I/O board cable: same
• Display: same
• SSD: same
• AirPort card: same
• Trackpad: same
• Fan: same
• Upper case cable: same
• Speakers: same
• Screws (for what it matters): same
• Heat sink: same
• Camera: same
• Battery: same
• Clutch cover: same

I think that is all the parts?

I've only tried the flat head screwdriver method at this point but realized it wasn't a solder point. Yes, I'm an idiot =P

Here's a photo of the board and I just marked locations where I think it might be located based on what I've read.

I figure if powers on then I will replace the keyboard but if it doesnt then it would also involve the logicboard in which case I wouldn't bother fixing it.

I just replaced the lcd of my macbook and now the backlight does not work. when I turn on the laptop, the lcd works but the backlight does not turn on. I tested with a couple of screens but no success.

Is the problem with the backlight LED, or fuse or logic board, is there any solution?

Model: Macbook air, 11 inches model A1370, 2011.

Any help would be highly appreciated

A couple of hours later when he went to turn the Macbook and that's where he first noticed the problem with the backlight. He says that when he first turned it on, the screen was very dim, but he was able to make out a dialog box on MacOS. Then he said it flickered and went completely dim.

When he gave it to me, the screen was completely dark. However, by shinning a light through the Apple logo, I was able to see the MacOS desktop and confirm it was the backlight that was not-functioning and not the LCD. I connected his laptop to an external monitor and was able to confirm that everything else was working fine.

At that point, my initial instinct was to just replace the display. I found a couple of eBay listings of Macbook Air displays that came with the full display housing. However, in the course of my research, I've read a lot of support threads identifying the Fuse on the mainboard of the Mac as the reason why backlights on the MBA might fail.

Here's a picture of the (what I think is the) fuse on the mainboard:

My Question: How do I know which is the right solution? How do I know if the Fuse is blown or not? Will buying the display off eBay solve the problem regardless? Or will I end up wasting money if it turns out to be a problem with the Fuse?

I have purchased a used MacBook Air 11" Mid-2012 and noticed that the screen hinge is loose. It sits tight and completely fine, but once you open it up to around 120ish degree angle it becomes completely loose. I've tried to tighten the hinge screws but it didn't seem to help.

I didn't manage to find anything in forums and I guess replacing the hinge wouldn't help because it seems intact and once I tightened the hinge screws it seemed to be even more tight up to 120-ish degree angle. Perhaps there's some sort of screen retainer that's broken off and could be replaced? :((

Does this sound like an issue with the logic board or the keyboard itself? The spill was on the lower part of the keyboard... space, fn, control area, and it looks like what's under it is mostly battery. I don't mind taking it apart and cleaning it, but do you think i'll need a new logic board?
