Chromebook Quality Control

Functionality Checks

Power / Battery

• Power device on, plug in power adapter and ensure the battery will take a charge:

  • Time remaining until fully charged should be displayed when connected to power adapter

• If battery is recognized there will be a battery icon in the bottom right status bar; if the device is not connected to a power adapter the icon, once expanded, will indicate percent charge and battery life remaining:

• On some models, if the battery has less than 1% charge the system will not recognize it. Before failing a device for a bad battery make sure to charge it long enough such that it would have more than 1% battery life

• Any device that has had any type of charging issue whatsoever (this includes problems with daughterboards, motherboards, charge ports and batteries) should be charged to 80% and then allowed to discharge a little to ensure 100% functionality with all power related functions, and QC should charge it to above 97% so that we know that it is charging correctly.

• Even if the battery is not replaced - Techs should have every device charged to 8-10% when pending a work order to QC.

LCD

• Should not be dim, black, or white and should be without serious blemishes:

  • If LCD is dim, on some models, holding power button for 10+ seconds and powering the device back on can sometimes fix dimness issue.

• Verify LCD cable is well seated by tapping firmly around both connections.

• LCD should be firmly seated in housing.

• Bezels should be snapped down around all sides and should be difficult to pull away from housing. Also, bezels should be level and without bumps or raised areas due to debris, broken clips and the like.

Keyboard / Palmrest / Midframe

• Navigate to a text field and verify each keyboard key works:

  • Typing, “The Quick Brown Fox Jumped Over The Lazy Dog” and “1234567890-=”

• Keys should not be sticky, falling off, and should work each and every time.

• No wires, electrical components or connectors (other than standard ports) should ever be exposed or visible.

• Any keyboard/palmrest/mid-frame damage is considered cosmetic only if:

• Functionality is not impaired.

• Structural integrity is not compromised (small cracks or breaks should not bend easily or come loose in any way under light pressure).

• There should be no gaps between palmrest/mid-frame/keyboard and the entire assembly should be snapped/screwed together firmly.

• If the device has any type of hinge cover it should be fully snapped in and without any obvious gaps, breaks, or bends.

• Breaks in midframe port housings can be accepted if the following conditions are met:

• Broken or sheared area is not sharp or jagged.

• Keyboard/palmrest is still snug and does not run the risk of coming loose due to broken port housing.

• The port itself is no more exposed than it would be if housing were not broken.

Trackpad

• Trackpad should make audible “click” when pressed on any area except along the top edge.

• When released after a click the trackpad should immediately click back into position:

  • Sticky trackpads will result in a QC fail.

• If cursor is jumpy make sure battery has at least 10% charge (on some models the cursor will not track properly on very low battery).

Wireless

• All networks in the warehouse should be visible and have relatively strong signals.

• QC Technicians can connect the devices to our non-internet wifi devices to check the wifi connection.

Sound

• Use Spoken Feedback (CTRL+ALT+Z) to confirm that both speakers are plugged in and functional. Do not send a device out the door with Spoken Feedback enabled.

• Verify the headphone jack is functional and firmly secured.

• Most chromebooks do not have high quality speakers and thus will have some sound distortion when volume is raised to a high level; this problem tends to worsen in speakers that are played at high volumes for extended periods. Some sound distortion is acceptable, good judgement should be used in determining if speakers should be replaced or not. A good rule of thumb when evaluating speakers is that if the customer has not raised issue with the audio playback then it is probably ok.

Other

• If a chromebook has had a motherboard swap performed:

  • The tech should properly change the S/N on the new board to match the old S/N.

  • The old vpd log should be cleared.

  • The device should be left in developer mode so that the QC tech can easily verify that the S/N was properly changed (A device not left in developer mode for easy S/N verification may not necessarily constitute a QC fail but rather a policy fail).

  • S/N on back cover should match both the board’s and work order’s S/N.

• Make sure all backplate/hinge screws are present and tightened down.

• Hinges should not be loose such that the LCD closes or falls down during normal use.

• Ensure all clips are snapped securely and that all plastics are snug.

• There should be no deformations/protrusions due to the installation of screws of inappropriate length. Any damage to plastics due to these protrusions will constitute a QC fail and require the damaged part to be replaced.
