Laptops :: Keyboard Marks On PowerBook Screen
Apr 9, 2010
I just acquired a 1 GHz 15" Powerbook Ti. It is in good cosmetic condition except for a few dark marks from the keyboard on the screen. I can feel them with a fingernail, so I know they are residue from the keys. Is there any way these can be removed without damaging the screen? I have had very good results using toothpaste and a damp cloth on other surfaces, but I am leery of using even a very mild abrasive on the screen. I have even used newsprint on some sensitive surfaces with good results but if you make an error on the screen, it is either permanent or expensive. I suppose I could try in a corner but I know there are anti-glare coatings on the screens and I could make things worse. This is most noticeable when there is a light-colored area displayed right under the marks.

I own a Black macbook (summer 2008, so about two years old) which is in good condition except that it is dirty - especially the screen, which seems to have picked up keyboard marks which won't seem to come out. I have been reading about the best way to clean it, and there seem to be 4 general suggestions:
1. Clean using a damp microfiber cloth like an eyeglasses cleaner.
2. Clean using a Mr. Clean Magic Eraser
3. Clean using soap & water.
4. Purchase a specific mac cleaning toolkit like iKlear.
I tried option (1) a while ago and it cleaned the black macbook's body pretty well but not the screen. I have heard that (2) is great for the body but that it will damage the screen because the magic eraser is like "damp sand paper." That doesn't sound very screen-friendly. I have also heard that (3) will damage the screen's protective coating, though theoretically soap should be able to lift off any oily residue on the screen. (4) could work but it is more expensive, and I am not sure if it will work or not. Modern macs are fabulous and should be good enough to last years and years. I am hoping this one will last at least 3 more, making a total of 5 years, but I want to keep it clean.

Just what I needed - another thing to obsess about! On my screen, corresponding to where the bottom line of the keyboard recess is, I have a horizontal marks on my screen. Does anyone else have this? I've tried buffing with some iKlear and a soft cloth but it won't go away. I can't see it when the screen's on but it's bugging me now, as these things tend to do. With my old Powerbook I kept the plastic sheet in between the sceen and keyboard but assumed this was not necessary with the recessed keyboards. Now it seems its the edge of the recess, rather than the keys themselves, which is the problem.

I'm new to MBP 13'' (2010), just 3 weeks now, and it's my first laptop, so I don't know if this is just normal or not. I have noticed there are several marks on screen appears to be from keyboard edges, say where the "E" key supposed to meet the screen. Looks like small spot scratches, but fortunately they came off when I clean them with damped cloth. It came back after I use and close/open the lid, same spots I think. New MBP design looks like the keys should not touch the screen, but it appears to be keep touching while lid is closed? What about yours, can you see marks when the screen is turned off? Or I may need to worry about screen protection? (if I do cleaning often the same spots I guess it may scratch eventually?)

I have an iBook G4 (14-inch screen, 1.42 Ghz.) and it has a cracked screen. I also have a PowerBook G3 PDQ (14-inch screen, 233Mhz.) with a good screen. Question: Can you swap the screens even if they were made 7ish years apart?

I have a Powerbook G4 that I bought used a year ago. It has worked perfectly with no problems at all. Yesterday it started going to sleep randomly during use. It would wake up when the space bar is pressed and be fine for a while. This was happening every 10 - 15 minutes. Since yesterday it has gotten worse and worse, happening more and more often, and now it won't even stay awake long enough to click on something. Any ideas of what could be wrong??? I'm sorry I don't know what operating system or anything, I'm not all that Mac savvy.

I have a very old PowerBook that did have OSX running on it fine. Recently it has stopped working completely and when you startup it takes you to a blue screen with a question mark and a finder icon flashing on top of a folder. If you give it long enough it will just shut off. I have tried booting from a CD but I can't seem to get that to work. I boot up holding down the option key and it brings me to a window with a picture of my hard drive and a picture of the CD drive but when I click the cd drive and then click the forward button it merely acts like it's refreshing the list and doesn't actually boot from the CD at all. I've also tried holding down C during boot up but it ignores that and just goes to the same old flashing question mark and finder icon screen. The CD I am trying to boot from is the same OSX cd that I originally installed OSX on this computer from so I know it works.

We have about 10 PowerBook G3/400 computers in our school running OS 9.2.2. They haven't been used in a couple of years and now none of them will boot up. No power. I checked Apple's website and found an article called Power Management Unit. It says to hit the reset button, wait 5 seconds and then hit the power button, but it didn't work for any of them. Does anyone have any ideas?

I recently inherited a Pismo, 400 mhz and a 6gb hard drive. Other than the tiny hard drive, the computer is in great shape and has a lot of service left in it. I was able to load Tiger on it, and it's working fine. I replaced the hard drive with a 100gb Seagate, but when I tried to format the disk,the new hard drive didn't show up during installation attempts. However, the volume was visible in the system profiler and the disk utility...I reinstalled the original hard drive, and that booted successfully so I guess that means I didn't damage the hard drive cable, which I had feared. Does anyone have an idea about this? So odd that that I could locate the drive in the disk utility but not at the installation screen.

My Titanium powerbook was running when suddenly the screen went crazy, flashing colors and bars, then went blank black. Now can't boot at all, even from external drive. If I hold down the start key I eventually get a faint humming sound and the little "alive" light at the bottom of the display bezel flashes for a short time. If I repeat this it takes at least 15 seconds to happen. I have turned it off for a while and even removed the battery but nothing changes. Can't afford a new one, need help to fix it.

A friend of mine has an ibook clamshell with black marks on the screen. He sent me a picture but I really can't tell if it is a broken screen or pixels or something else.

I have been using Mac's for several years. I just replaced my Macbook with the Air. My brother had an Air from the first go around but recently sold it. I did mention to me to always keep the little microfiber cloth on the trackpad when I close the computer as after time it will start to leave marks on the screen.

I'm thinking of buying a MacBook but I have one reservation. I'm moving from a Powerbook 12"...
What's the consensus on the MacBook keyboard in terms of ease & comfort of use? I write for a living so a good keyboard is pretty essential. I've always been mostly satisfied with my powerbook keyboard, it's pretty comfortable although I occasionally mash a neighbouring button with my big clumsy fingers. The MacBook keyboard looks a little... weird. How is it?

I have a IBook G4 using OS X. The "2" and "w" keys do not work. Was wondering if these keys can be popped up and cleaned under neath or if there is any other easy fix.

I was doing an upgrade of the hard drive in a MBP and unfortunately when I removed the keyboard the ribbon cable attaching it to the MBP's Logic Board came off and I can't figure out how to reattach it. I know it there has to be a way to reattach it but I don't want to attach it wrong and have something short out. How would I go about reattaching it?

I disassembled my MacBook to repair a jammed optical drive. I have two problems: the first is while testing that the optical drive now worked (I tested it will it was still partially disassembled, and it did work) I noticed the track pad and keyboard were not functioning. Obviously the power button works, and the machine booted fine, but the trackpad and the keyboard don't work at all. I had to plug a mouse in to move the pointer. I should note that yes, the trackpad cable was indeed firmly plugged in.
However, at one point when trying to reassemble the top case, the trackpad cable detached from the plastic piece that plugs it into the logic board. I removed the plastic piece, slid it back into place over the wires of the cable and then plugged it back in. So I'm wondering if this means I need a new trackpad cable? My second problem is that upon full reassembly, the machine will not turn on. The power button doesn't work when the top case is firmly back in place and the rest of the machine reassembled. I have no idea what might be causing this.

I just purchased a 15" MacBookPro (July 2010). I am not used to laptop keyboards so I was able to purchase a bluetooth Apple Keyboard with the Numeric keys. This bluetooth external keyboard was made by Apple and a local company had these brand new for $60. I was told they were the model that came with iMacs. Apple support told me that they should work fine but did not offer an effective solution. So at any rate about 70% of the time this Bluetooth keyboard works great.
But sometimes when you go to type something it starts repeating whatever key you hit so it you were to type and "a" an example the MacBookPro displays "aaaaaaaaaaaaaaa". Sometime just a few of the same character and sometimes it does not stop. I correct this by turning the power switch off on the Apple Bluetooth keyboard and then turn it back on and all is fine, for a while. Sometimes for a week or so then it will do it a lot for a while or just intermittently. The keyboard built into MacBookPro does not do this. I think it may be the Apple Bluetooth keyboard not the MacBookPro or its OS.

I can't seem to find instructions on the Apple Support site on how to remove the keyboard from a 12" Powerbook.
Can someone here explain to me how to remove it? One of the keys is sticky, so I'm hoping that I can just pop off that key and clean it. And I guess I should ask what the safest way of popping out a key is .. don't want to break anything!

Everytime when I'm on my Powerbook after 1 hour, sometimes my keyboard messes up.
All the letters turns to letter and symbols.
I reboot the laptop and its fine, this only happens every now and again.

Which one? (i believe the Aluminium Powerbooks and the MacBook Pros are using the SAME keyboard, so which one you like best? my girlfriend had an ibook and the keyboard was "alright", better than ALL the PC keyboards out there, but i had an AlPowebook and that keyboard was BLISS!! i currently own a Blackbook and i REALLY dig the keyboard, but the powerbook's keyboard was by far the coolest/easiest/most confortable keyboard EVER.

I Have an Aluminum 1ghz Powerbook G4, the only keyboard key that is backlit is the caps lock key so i assume that it is not a backlit keyboard. Anyway, What is involved in adding a backlit keyboard or is it even possible?
