    There is definitely a fuse. Check this: http://hondaaccordforum.com/forum/archiv...-1759.html

    Yes, they can. Please refer to this partial teardown: http://forum.tabletpcreview.com/ep121-slate/38468-look-inside-ep121.html
  • Answer to: new battery, dies everytime mower is stopped.

    From the ignition switch, follow one of the red wires to a fuse holder. Check that fuse and replace it if necessary. Check the other red wire and follow it to a 3-pin connector. Make sure that connector is fine, and then keep following the wire to a diode. If everything else is good, then you might try replacing that diode. It might be internal to the motor, though. I found the parts diagrams for your mower by searching for murray + the model number. They showed the wiring diagram. You can also get replacement parts there.
  • Answer to: What can I do to release the sim tray?

    Edit: Victor's idea of using a 0.1mm metal feeler gauge looks like the best solution. It needs to be inserted into the side closer to the screen. If there's any room to slide a piece of paper or mylar plastic between the top of the tray and the slot, then that piece of paper or plastic may help prevent the card from hitting the side of the case. You might try shoving the plastic in deeply, the pulling on it a little as you try to release the card. Also, have you tried holding the iPad with the screen facing up while trying to release the tray? If you look at the first picture in the iPad 2 3G/CDMA teardown, you'll see what the problem can be. If you made the card a millimeter too short, the SIM spring contacts will push the SIM up against the chassis and prevent it from ejecting. You'll need to find some way to shove something, whether flat like paper or perhaps something like a stiff thin wire, into the space between the tray and the slot and use it to keep the card's front edge down as it is ejected. If the...
  • Answer to: Where is the GPS in CDMA iPad?

    Apparently, the Qualcomm MDM6600 performs that function. At least, that is what everything thinks (as shown by a web search).
  • Answer to: Need to get into DFU mode - broken home button

    First, I'd try to diagnose the home button a little. If you hold multimeter probes to the button contacts, does the meter register any continuity when you press the home button? If so, then the switch itself works, and you need to try and clean the contacts. Otherwise, you can get a replacement front panel pretty cheaply (not including the LCD). Short of that, though, you might try just lifting the front panel up just enough to touch the mating contact points with a metal object to short them together (ie, this should electrically be the same as pushing the button). If you look at step 3 of any of the guides, you should see the two gold squares between the fingers of the left hand; those are the button's mating contact points.
  • Answer to: How to open Seagate ST90000U2-external hdd case & remove drive

    I had a case like that; I believe I was able to remove the screws using a small flat screwdriver that was able to fit tightly enough into the screw head. Once I removed the screws, I replaced them with regular phillips head.
  • Answer to: How can I fix a garbled e-ink screen?

    Screen problems like you describe could be due to the flex cable not making proper contact with the circuitry on the glass layers. This may or may not be easily fixed, depending upon how the cable is attached. Sometimes there's just a clamp that requires more pressure. But usually it's bonded with adhesive, and this may be impossible to deal with without specialized equipment. But if you are able to open up the device and still have it operable, sometimes you can just try squeezing on different parts and see how that affects it.
  • Answer to: Problem with the Canon PowerShot A80 Digital Camera

    If the new pictures you take don't look right, then this sounds like a CCD imager failure. Canon has an on-going free repair program for this. See this link: http://www.usa.canon.com/cusa/support/co... However, if the new pictures you take look okay, then you've got another problem.

Notes

  • Macintosh 128K Teardown

    One point to remember when disassembling a compact Mac: If you've installed the "Reset/programmer's buttons" over the vents at the bottom side back corner, you should pop them out before removing the case back. Otherwise, they'd tend to snag on the motherboard back plate. The buttons provided a way to reset the Mac without having to turn it off. There was also a NMI (non-maskable interrupt) button that could be useful for programmers (like a hardware ctrl-C to break into a hung program).

  • Macintosh 128K Teardown

    Ah, the Hyperdrive: http://www.flickr.com/search/?q=hyperdri...

    I was thinking of something like the Dove MacSnap: http://www.vintagemacworld.com/macsnap.h...

    The Hyperdrive was pretty rare & expensive, whereas upgrade kits like the MacSnap eventually became cheap & common.

  • Macintosh 128K Teardown

    You're thinking of the SCSI interface upgrade. It clipped over the CPU and a ribbon cable was snaked out through the battery door. As far as installing an internal drive, you had to remember that it would be a while before 3.5" HDs would even be available, and that they were initially the same height as 5.25" 1/2-height drives (full height being about 3.25").

  • Oculus Rift Teardown

    A USB2.0 adapter would not be suitable for fast-action video. I wouldn't count on the other options, either. You can find cheaper adapters than the one I pointed out, which was just the first I happened to come across. Another example is: http://www.ambery.com/2covivgatodv.html

    Actually, looking at the specs for your notebook, you should have a DisplayPort, and you can get a cheap adapter from that to DVI-D.

  • Oculus Rift Teardown

    You would need something like this:

    http://www.datapro.net/products/vga-to-d...

    It requires a converter with active electronics; a passive adapter would not work.

    A different rev. of the Rift might support analog input, but this one does not appear to have the signals hooked up (based on what I can see, which isn't quite enough).

  • iPad mini Wi-Fi Teardown

    I think they are getting a little more impatient in their teardowns.

  • iPod Touch 5th Generation Teardown

    It looks like the mistake here was pulling off both the yellow/green flex circuit and the black tape at the same time. Presumably, if you'd lifted off just the black tape, you would have been able to unsolder the flex circuit from the logic board.

  • iPod Touch 5th Generation Teardown

    Could you please show an image of the other side of the motherboard?

    I'm trying to understand how the battery connects to it.

  • MacBook Pro 15" Unibody Mid 2012 Teardown

    Are you going to attempt to tear down the screen assembly?

  • MacBook Pro 15" Unibody Mid 2012 Teardown

    Yes, but compare the area of two side-by-side DIMM sockets & modules vs. that of just the chips, and you'll see why the Air doesn't use DIMMs. (And compare that area to that of the entire motherboard.)
