Test adapter for voltage
1. Plug adapter into a working outlet.
2. Turn on meter to test for DC voltage.
3. Put one lead into the end of the plug and the other lead to the metal on the outside.
4 The adapter will be labeled 9VDC or 12VDC. When testing, the reading should be a few volts higher than the label says. If there is less voltage than what the label says, you need to replace the adapter.
Test harness for power supply voltage
1. After you have tested the adapter for voltage, plug in the machine and take the console off of the unit.
2. Turn on the meter to test for DC voltage.
3. Put one lead on the 1st wire and the other lead on the 3rd wire.
4 You should have basically the same voltage here as you had when you tested the adapter. If the reading is vastly different, the harness needs to be replaced.
Test gear motor
1. If unit is an XE550, go to motor test in engineering mode.
2. Take off right shroud so you can access the gear motor.
3. Turn meter on setting to check for DC voltage.
4. Check for voltage between the yellow and the red wires. (Should be around 4.5v for 350/550)
5. Check for voltage between the yellow and orange. Check for voltage between the red and orange. These two voltages should added together should total the voltage that you had between the yellow and red.
6. Press the START button and press the UP button. Check for voltage between the black and the brown wires. You should get 4-6 volts. (As you can see, you will need someone to help you with this step.)
Alignment of speed sensor and magnet
1. Using a flat screw driver or a knife, take off the round disc cover on the left side of the unit.
2. Turn the pedal so the bigger opening is at the top of the hole.
3. Sensor should be pointing directly at the large pulley and there should be a magnet in the on the pulley.
Adjusting brake cable
1. Take right and left shrouds off.
2. On the left side of the unit you will find the brake inside of the flywheel.
3. Using an open end wrench, loosen the small lock nut.
4. Using the same wrench, loosen the longer nut. As you loosen the nut you will see this gap get smaller.
5. The smaller the gap is, the easier the resistance will be at level 1. Dont adjust out the gap completely.
6. Tighten down the lock nut.
XE400 and XE500 Incline Calibration

MOTHER BOARD REPLACEMENT PROCEDURE 
Pry with a plastic opening tool, or your fingernail, in the divot to the left of the rear-facing camera, near the power button.
Lift the rear case by the corner nearest the divot and remove it from the phone.
Use the flat end of a spudger, or your fingernail, to press the microSD card slightly deeper into its slot until you hear a click.
After the click, release the card and it will pop out of its slot.
Remove the microSD card.
For reassembly, push the microSD card into the slot until it clicks in place.
Insert a plastic opening tool, or your finger, into the notch of the battery compartment and lift the battery upward.
Remove the battery from your phone.
Use a plastic opening tool, or your fingernail, to press the SIM card slightly deeper into its slot until you hear a click.
After the click, release the card and it will pop out of its slot.
Remove the SIM card.
During reassembly, push the SIM card into the slot until it clicks in place.
Remove the nine 4.0 mm Phillips #00 screws securing the midframe to the display assembly.
The midframe is secured to the display assembly by several plastic clips behind the chrome bezel of the midframe. The next few steps will guide you through separating the clips to free the midframe.
Starting on the volume button side of the phone, insert your plastic opening tool between the chrome bezel around the display glass and the larger chrome border piece. Look for the seam between the two.
Slide the opening tool along the seam, separating the plastic clips as you go.
Be very gentle whilst prying, and pry only enough to separate the plastic clips—there are several thin points in the midframe bezel that may crack if you bend them too much.
Continue prying around the corner of the phone.
Slide your opening tool along the seam between the midframe and display along the bottom of the device, releasing more of the plastic clips.
Again, pry around the corner, to the power button side.
Slide the opening tool along the seam.
Continue sliding the opening tool around the top of the phone, releasing the last of the clips and freeing the midframe from the display assembly.
At this point, you may want to run your plastic opening tool along the entire perimeter of the device again, to make sure you've released all of the plastic clips.
Remove the midframe from the display assembly.
Use the flat end of a spudger to disconnect the USB board connector.
Disconnect the front-facing camera cable connector.
Disconnect the earpiece speaker assembly cable connector.
Disconnect the headphone jack assembly cable connector.
Disconnect the display/digitizer cable connector.
Disconnect the antenna cable connector.

Gateway KAV60: Cooling fan replacement procedure 
Unlock the tab located in the top left corner of the netbook. The red tab indicated that the battery has been properly unlocked. Remove the battery. When working with electronics, it is always wise to remove the power source before taking the device apart.
Make sure the RAM, hard drive, and WiFi card have been removed from the computer before trying to take off the cover so they are not damaged in the process.
Remove six (6) 5mm screws, two (2) 17.5mm screws, and three (3) 2.5mm screws from the back, using the Phillips #0 screwdriver, as marked here.
Pry off the keyboard by placing your plastic opening tool in the exact location shown in the photograph. You may need to use something sturdier than the plastic opening tool, like the screwdriver.
Remove the five (5) 5mm screws shown here using the Phillips #0 screwdriver.
Separate the upper cover from the back cover. It is possible to do this without a tool, but you may also use a plastic opening tool for added leverage. Be careful to keep even pressure all the way around the cover so that it is not bent beyond repair.
The WiFi card is shown here. Remove the one (1) 5mm screw holding the card to the motherboard using a Phillips #0 screwdriver.
Disconnect the wires on the WiFi card. This can be done easily by applying pressure to the connections until they pop off of the card.
Using a Phillips #00 screwdriver, remove the four (4) 5mm screws holding the motherboard in place. Remove the motherboard by lifting it gently from the bottom cover. This image is the rear view of the motherboard.
Begin with the motherboard of the computer, as shown here. Using the #00 Phillips head screwdriver, remove all four (4) screws marked here.

Apple iPhone 5 Front-Facing Camera – How to replace the frond camera


Apple iPhone 5: HOW TO REPLACE THE FRONT CAMERA 
If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.
Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered.
This will keep glass shards contained and provide structural integrity when prying and lifting the display.
Wear safety glasses to protect your eyes from any glass shaken free during the repair.
Before disassembling your iPhone, be sure it is powered off.
Remove the two 3.6 mm Pentalobe screws next to the Lightning connector.
In the following steps you will be pulling the display up out of the phone body. The display is composed of a glass screen and a plastic bezel with metal clips.
Regardless of the tool you use, you need to be sure you pull up the entire display.
If the glass begins to separate from the plastic, as shown in the first image, slide a plastic opening tool between the plastic frame and the metal phone body to pry the metal clips out of the case.
If you are reassembling a phone with a separated display bezel, you may want to place a thin strip of adhesive between the plastic bezel and the glass to keep the phone closed.
The next two steps demonstrate using the iSclack, a great tool for safely opening the iPhone 5 ,its recommend for anyone doing more than one repair. 
Close the handle on the iSclack, opening the suction-cup jaws.
Place the bottom of your iPhone in between the suction cups, against the plastic depth gauge.
The top suction cup should rest just above the home button.
Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.
Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case.
The iSclack is designed to safely open your iPhone just enough to separate the pieces, but not enough to damage the home button cable.
Peel the two suction cups off your iPhone.
Press a suction cup onto the screen, just above the home button.
Be sure the cup is completely on the screen to get a tight seal.
If you're opening an iPhone with cracked glass, neatly lay a couple strips of packing tape across the front and squeeze out as many bubbles as you can. This will give the suction cup a surface to grab, and minimize the spread of broken glass.
Make sure the suction cup is firmly attached to the front panel assembly.
While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.
Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.
With a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while you pull up with the suction cup.
There are several clips attaching the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.
Continue to pry up around the sides of the front panel assembly, detaching the clips along the left and right side.
Do not try to completely remove the front panel assembly from the rear case, as there are several ribbon cables still attached at the top of the iPhone.
Be sure to disconnect the battery first before proceeding with the repair as not doing so can sometimes cause the phone to run hot and/or have issues with touch sensitivity.
Once the clips have been released on the bottom and sides of the front panel assembly, pull the bottom of the assembly away from the rear case.
Lift the front panel assembly slowly up to about 90 degrees from the rear case.
Remove the following screws securing the front panel assembly cable bracket to the logic board:
Two 1.2 mm Phillips screws
One 1.6 mm Phillips screw
This screw tends to not be attracted to a magnetized screwdriver. Take care not to lose it when removing, and make sure it gets back into the right place—a magnetized screw may interfere with the compass.
Remove the front panel assembly cable bracket from the logic board.
User note: To ensure correct installation, make sure you clip the small hooks of the
bracket under and then lower towards the outside of the phone.
Use a plastic opening tool to disconnect the three front panel assembly cables:
Front-facing camera and sensor cable
LCD cable
Digitizer cable
When reassembling your phone, The LCD cable may pop off the connector. This can cause white lines, or nothing at all to appear when powering your phone back on. If that happens, simply reconnect the cable and power cycle your phone. The best way to power cycle your phone is to disconnect and reconnect the battery.
Remove the front panel assembly from the rear case.
Remove two screws securing the front-facing camera bracket to the display assembly.
One 4.1 mm Phillips screw
One 2.2 mm Phillips screw
There is a small, black plastic spacer underneath the metal bracket at the upper screw. The upper screw goes through the metal bracket then through this plastic spacer.
 Remove the earpiece speaker bracket from the display assembly.
 Starting under the earpiece speaker contacts, use a plastic opening tool or the tip of a
spudger to pry the front facing camera cable out of the display assembly. Caution: Removing the earpiece speaker contacts can cause them to tear. Use extreme caution when peeling the contacts up.
Remove the front-facing camera and rear microphone assembly.
If you are installing a new part, your new part may have two tabs with holes in it used for manufacturing purposes. These tabs can be cut off with scissors.
There is a small, square plastic and metal holder for the proximity sensor. This holder is essential for the proximity sensor to function correctly.
If replacing the proximity sensor or camera make sure that the holder remains adhered to the back of the display. If it comes off with the old proximity sensor, remove it from the old sensor an use a tiny bit of adhesive to re-attach it to the back of the display.
