  • My son had the same problem with his. The hight was a little more I think but same symptoms. Cost is $1200 to replace the whole screen. Apple would not just fix the back light. This was for the 17inch Mac Book Pro. The 13' should be much less. Apple may just fixit if there is no visible damage. He had obvious physical damage.
  • Hi All, I have a problem with my backlight of my macbook air, when it suddenly stopped working. I sent to apple for diagnostic, which initially they assume it should be whether the logic board or the display, and after 4 days they said that it's the display and the cost to replace it would be around £450.

I tend to use a window. Of course this only works in the daytime.

I'd be very leery about doing this without something transparent and HARD like a sheet of glass between whatever I'm tracing with (pencil? pen? marker?) and the screen.

That sounds like a really bad idea, depending on the implement you're using to trace. The last thing you want is some permanent marker on your screen because you slipped!

Permanent marker is easily removed with rubbing alcohol or some other alcohol-based cleaner.
Also, since I was using an 8.5x11' paper on a 13' diagonal screen, there was no danger of slipping off the paper.

You call this a hint? Please bring Rob back.

This is a hint? Is there an editor? Other ideas: use your mini as a paperweight or panini press...

Using an iPhone screen as a backlight isn't a terrible idea. There's a layer of hard glass between you and the soft screen.
But a laptop? The kind of screen that gets dark spots if you poke at it? This seems like a recipe for having whatever you're tracing permanently visible on your screen.

Caveat: Only do this if your device has a glass screen. You don't want to do this on an Air!
I've never used a computer for a lightbox, but I've used a window on a sunny day. It's awkward but it works when you don't have one around. I also have a glass coffee table, mostly because it looks good, but the fact that I can throw a light under it to use as a light table is certainly a bonus.

Terrible idea. So easy to accidentally press too hard and crack the screen..

If you press that hard, this tip is not for you. ;)

And in case you have no tools near, you can use it as a hammer..
..or a door stop..
..or to level a table with a shorter leg..
..or use a dozen of them as pilates..
..as a frisbee..
..and of course, as a notebook.
Lot of uses!
:)

Excellent. Good clean fun. Thanks to original poster and this commenter.

I was serious when I made this post. I did it, and it worked for what I needed to do. ;)
I'm sure it could work for all the things you suggested, but at 1.25' thick, using my laptop as a doorstop would probably not be very effective. That, and I'm not in the market for a new one.

Thank you for sharing, wallybear. I'm having trouble, though, using my macbook air as a frisbee. I'm running 10.7.3 and everything else is working just fine. The folks at Apple Care say this is a known issue, and can be traced back to hardware rectangularity, but they've been less than forthcoming about a solution. Any help would be most appreciated.

There is a simple solution to your problem.
Just buy or borrow another MacBook and use it as an hammer on the edges of the four corners of your future frisbee, until you get a rounded shape: the rounder the better. It will require some trial and error, but eventually you will succed.
Just please don't launch your shiny new frisbee at your dog, it could get hurt.

I've used an LCD monitor (not on a laptop) as a light table for negatives; open a blank browser window in full-screen, shoot with a digital camera, and invert in Photoshop. The quality is not good, but it's sufficient for a contact sheet of large-format negatives so you can decide which ones you want to pay to have scanned.

You guys are being kind of harsh. I had to do this on occasion when I was an art student and my laptop is still in mint condition. It actually works well in a pinch.

Agreed. It's not like the submitter's telling little kids to do it. If someone posted a hint about using the edge of an Air as a bread knife, I'd just decide that it wasn't for me.

Really? Do you mean it cannot be used for bread? It could work as a cake knife? For butter? For taking apart oysters?
Don't take it too seriously, let's us joking a little, life is so short.
And remember, if you need to trace a really little sketch, you can use your iPhone with similar results.
:D

It is true, this is primarily a glass-screen tip. I specified my model.
Damage would only occur if you press really, really hard. We're talking a pencil here. I used B-hardness lead, which may affect the outcome. Don't press any harder than you would for normal writing—you're not doing an etching.
A window would have worked, but I was at a part of a library where there were no windows.
I'm also the guy that drew on the lid of my laptop with a pencil. ;)

I matched an old iBook with a white screen set up and 2 refurbished APC UPS batteries for emergency light ( as well as audio player/ recorder, & music alarm clock,. I have only used it once in the last 6 years and the screen lit up the entire room for over 40 min on one battery before the electricity came back on. I have not bothered calculating how many minutes each battery would provide. I have not had to change batteries yet, but replacement lead acid batteries are less than 20 bucks.

I have used the screen of a laptop as background light for experimental photography with great luck. I used an old IBM Thinkpad as I wouldn't risk my beloved MBP. ;o)) It is n fact a very funny idea, as You have a polarized glass in front, and if You place some plastic objects on the screen, and use a polarizing filter on your camera, you can get many funny results.
