  • Hi and thanks for the post! First I would note that the 1.67GHZ 15" PowerBook definitely requires the 65W version of the AC adapter (as opposed to the 45W version), so that's the first thing I would check. A 45W would fail to charge the batte…
    in Powerbook G4 15" 1.67 Battery issue Comment by John May 2016
  • Hi Max! In our previous conversation you stated that you are getting a black screen with no faint image and a glowing sleep light, which is the most telling detail. Because the sleep light is on, you know that the computer is not even trying to pu…
    in White MacBook No Chime Black Screen Sleep Light Stays On Comment by John April 2016
  • Hi! A laptop should function with the PRAM battery removed, however you won't have the benefit of any of your PRAM settings being saved, such as default screen brightness, default volume level, time and date settings, etc. This generally gets an…
    in PowerBook G4 Titanium Mercury Comment by John April 2016
  • Hi! Thanks for the post. This is an odd problem. When target mode is working, do you see the target mode symbol on the screen, or is the screen completely black? Based on what you're saying I'm assuming it's black. Lack of external video woul…

  • WTF, have you started climbing trees as a hobby, or is Google Earth just getting really amazing?

  • (Image) It worked! Only seems to take ones of certain size, but hey there's got to be a limit.

  • Great to hear, and sorry for the late reply! You should really make a YouTube video outlining the process -- it would be very popular, because this is a common problem. What brand/model EFI programmer is it?

  • Wow, you're beyond my experience with this, so I have no advice to offer unfortunately. But let me know how it goes -- I'm curious! Thanks
    in efi macbook air a1370 mid2011 11" Comment by John October 2015
  • Thanks for the post. That is a good idea...unfortunately I haven't tried it myself. I guess the question here is whether or not the lock ties itself to the OS installed on the drive, or to the hardware ID of the SSD module. In older Macs, the key…
    in efi macbook air a1370 mid2011 11" Comment by John October 2015
  • Honestly, I don't know how to do board-level repair, so I can't help with that. You would need a rework station, and very specific experience. There's no telling whether the procedure would even help the situation. I would definitely recommend bu…
    in Powerbook G4 12" Not runing, only beep !!! Comment by John September 2015
  • Hi! Yes, I believe those are the internal RAM chips. However, I don't know how to disable them.
    in Powerbook G4 12" Not runing, only beep !!! Comment by John September 2015
  • Unfortunately I've never found a solution for PowerBooks or iBooks in this situation. I have heard of people altering the logic board and then updating the configuration in open firmware to only use expanded RAM, but I don't know if that is somethi…
    in Powerbook G4 12" Not runing, only beep !!! Comment by John August 2015
  • Unfortunately 3 beeps indicate a memory error, and since no memory is installed in the slot, that means the memory on the logic board is most likely at fault. Since the onboard RAM is part of the board and non-removable, there's not a lot you can d…
    in Powerbook G4 12" Not runing, only beep !!! Comment by John August 2015
  • Thanks -- I saw the video. I would pretty much proceed as I described above, i.e. remove the battery, take off the memory cover on the underside, remove the RAM, and see if it powers up. If it does, we can go from there. If not, I'd reset the PRA…
    in Powerbook G4 12" Not runing, only beep !!! Comment by John August 2015
  • Hi! Thanks for the post. I don't see a link to the video. Beeping is usually related to memory -- how many beeps are there, 3 or 4? The number of beeps indicates the problem. I would remove the memory from the slot and see if it still beeps whe…
    in Powerbook G4 12" Not runing, only beep !!! Comment by John August 2015
  • No, I wouldn't put another cent into that laptop -- it's obvious it still has the GPU issue. The GPU issue comes and goes in its severity. It's possible if you don't power on the computer for a week it will boot up and be fully functional...for an…
    in Do I need to replace logic board or something else? Comment by John August 2015
  • Thanks for the post! It definitely sounds like you're dealing with the common GPU issue. These machines also sometimes have a bad RAM slot, but as long as you've tried a single module in each slot and with the other slot empty, you've most likely …
    in Do I need to replace logic board or something else? Comment by John August 2015
  • Hi! Sorry for the delay. Do you see an arrow or the progress dial? All of those things (except for the time) would tend to indicate that the hard drive is going bad, especially if you see a spinning progress dial rather than a pointer. I certain…
    in Do I need to change internal battery? Comment by John August 2015
  • Thanks for the post! I specialize in Apple laptops, so unfortunately I don't have much to offer in the way of iMac-specific advice. Have you booted to an external drive, or wiped the OS, in order to rule out software? I would also do all of the r…
    in mid 2011 iMac Logic Board - NO USB, WIFI, BLUETOOTH or SDCARD Comment by John August 2015
  • Thanks for the post! Unfortunately I don't have much advice, since it sounds like you've done just about everything. Have you tried connecting an external keyboard? If the keys don't work on that keyboard, that would absolutely verify it's a boar…
    in left shift & left ctrl & left option keys not working Comment by John July 2015
  • It's amazing to hear that the video is still getting watched...I made it 5 years ago...ah, the wonders of the Internet. :-) Thanks for the heads up on the Accept button, and I'll let my "web guy" know. Good luck! John
    in MBP 3,1 video issue Comment by John July 2015
  • I don't have a specific machine in mind, but I'd be sure to get an i5 or i7 processor, since you're not going to get a significant performance increase if you get another Core 2 Duo. If at all possible, the 2012s are generally good to go with becau…
    in MBP 3,1 video issue Comment by John July 2015
  • Thanks for the post! Yes, it does sound like the Nvidia issue unfortunately. Distortion of the screen is a classic sign -- usually lines, or a checkerboard pattern. In the beginning stages, the screen will distort, but the laptop can still be usa…
    in MBP 3,1 video issue Comment by John July 2015
  • Hi! Thanks for the post! First I'd say that soaking in an alcohol bath is probably not the best way to resolve liquid damage. The corrosion/Gatorade needs to come off the board, and letting it soak until evaporation does not necessarily remove it…
    in MacBook Pro 15" Mid 2009 Battery not recognized Comment by John June 2015
  • Really interesting info, thanks for posting! I had no idea there were so many complexities to it.
    in MacBook Pro Nvidia 8600M GT replacement Comment by John April 2015
  • Hi, and thanks for the post! First off, it's extremely odd that a tech should determine a battery is bad after the computer experienced liquid damage to the location you indicated. I would be suspicious of this tech. And unless you have a very ne…
    in MacBook Pro 13" Not Charging/Recognising Magsafe Adapter after (slight) water damage Comment by John April 2015
  • Hi Mike! Thanks for the post! Very interesting question...to be honest I have no idea whether or not the 128MB version is more or less vulnerable. I have learned to be suspicious of the 8600 in general, and I try to get rid of laptops that have…
    in MacBook Pro Nvidia 8600M GT replacement Comment by John April 2015
  • Hi! First off, I apologize for the delay -- sometimes there is a glitch with my website that causes me to not see a notification of a new post. Anyway, unfortunately, there is no other fix than a new logic board. There may be a solution in the wo…
    in Bad RAM Slot Mac - Not Giving Up! Comment by John April 2015
  • Thanks for the post! If it looks fine on an external monitor, the problem tends to be the laptop's screen and not the logic board. You have proven that the GPU is able to display correctly on external hardware, so if it's distorted on the laptop's…
