Notebook Troubleshooting Fact Sheet 2.11.7
Question | Answer |
---|---|
True or false, due to the integrated nature of laptops, troubleshooting notebook components is significantly harder than troubleshooting desktop components? | True |
True, or false, notebooks can run from either AC power through the transformer or from battery power? | True |
When troubleshooting power, verify that; the cord from the AC outlet to which component is correctly plugged into both the wall and the adapter unit, and you should move it around to see if a more secure connection can be made? | Power adapter |
When troubleshooting power, which component should you verify on your power adapter is lit? | LED light |
What component if not lit, on your power adapter means that your point of failure is between the outlet and the adapter? | LED light |
When troubleshooting power, which component should you verify is sufficiently charged? | Battery |
If the battery reads it is fully charged in Windows, disconnect your laptop from its power source. If the battery lasts only a short amount of time, what can you assume needs to be replaced? | Battery |
If the computer runs for only a short time even while plugged in, what component is most likely bad? | Power adapter |
If the adapter is not working, the computer will run off of the battery until the battery is drained. What two things can you do? | Try known good power adapter, or measure DC output power. |
When you experience video problems; what is one of the first things to try to do to switch the display output to the laptop monitor? | Press the Fn (Function) and the appropriate display key |
What should you check to make sure the backlight is not turned down all of the way? | Screen brightness levels |
What feature do some notebooks have that dims or gets brighter based on the available light? | Automatic backlight |
If the display is very dim, what is the most likely cause? | Failing inverter |
If the display is very dim, the most likely cause? is a failing inverter. What other component might also be the cause? | Backlight |
True or false, to test the inverter or the backlight, use special testing tools or replace with components that you know to be working? | True |
If the built-in monitor isn't working, connect an external monitor to the laptop. How would you direct the output to an external monitor? | The Fn keys |
If you don't get a display on either monitor, you can assume that there is a problem with the video card. Depending on the computer, you might be able to replace the video card, or you might need to replace which component? | The motherboard. |
If the display renders on the external monitor but still won't render on your laptop, then you can assume that there is a problem with which component? | LCD display |
If the display renders on the external monitor but still won't render on your laptop, what should you verify is working, and not stuck in the off position that might prevent the display from being sent to the LCD? | LCD cutoff switch |
If the display renders on the external monitor but still won't render on your laptop, which component should you check for cracks that might indicate the LCD has been damaged? | Bezel |
If the display renders on the external monitor but still won't render on your laptop, which cable bundles should you verify are not cracked or damaged? | Power bundles |
What is a term for areas on your screen (sometimes entire rows or columns of pixels) that no longer work? | Dead spots |
If you have dead spots what component is bad? | LCD assembly |
If you have dead spots, which component is no longer functioning and you will need to replace? | LCD assembly |
True or false, it is often cheaper to purchase a new laptop computer than to replace the display? | True |
A flickering screen can be caused by which faulty components? | Backlight or inverter |
If you know that your LCD needs to be replaced but you don't have the resources to buy a new LCD or a new laptop what should you consider? | Connect an external monitor permanently |
If you know that your video card needs to be replaced but you don't have the resources to buy a new video card what should you consider? | Remote desktop |
What are the most common portable components used with laptop systems? | keyboards, mice, digitizer pads, and antennae |
True or false, a bad keyboard can be tested by plugging in an external keyboard to your laptop and seeing if it works. If it does, you can assume that your laptop keyboard is malfunctioning and needs to be replaced? | True |
True or false, most notebook systems have features that cause keyboard keys to perform alternate functions, such as emulating 10-key functionality by turning on the NumLock? | True |
True or false, before troubleshooting other problems, make sure that no special features are enabled that may cause keys to perform alternate tasks? | True |
What typically causes mouse malfunction on a laptop? | Installation of an incorrect driver |
True or false, good indicators that the incorrect driver has been installed are if the laptop mouse's sensitivity isn't consistent or if the mouse doesn't recognize a double tap? | True |
What is used in laptop and PDA systems to receive input? | Digitizer pad |
Digitizer pad input is written onto the pad with which type of device, then those motions are transferred into data that is processed by the system? | Stylus pen |
True or false, if the digitizer pad becomes scratched, the laptop or PDA cannot receive input correctly | True |
a scratched digitizer pad is easily resolved by buying a cleaning product called? | Screen clean |
what product removes the top layer of plastic from the digitizer pad, thus removing existing scratches and giving the pad a fresh surface? | Screen clean |
True or false, you will need to replace the digitizer pad or buy a new system if the scratch is too deep? | True |
what is the term for when a digitizer pad's pressure sensors need to be realigned? | Drift |
How do you fix digitizer pad drift? | Recalibrate the digitizer pad |
True or false, it is always best to address digitizer pad drift issue before it progresses to the point that you can't access the recalibration utility? | True |
True or false, Though laptop antennae are supposed to be omni-directional, they sometimes need to be re-oriented to get the best reception? | True |
True or false, if you need to re-orient the laptop antennae, this can usually be done by moving the laptop until the reception picks up? | True |
True or false, if redirecting the antennae doesn't work and wireless reception is consistently poor, the antennae may need to be replaced? | True |
True or false, many laptops include a switch that turns the wireless network card on and off. When troubleshooting wireless network connectivity, make sure the switch is turned on? | True |
True or false, as long as your laptop runs, you can substitute an external device connected to a PS/2, USB, PCMCIA, or ExpressCard slot for most failed components, allowing you to continue using the computer? | True |
