12.7.1 Common Laptop Issues
Learn how to troubleshoot several common notebook computer issues.
Power Issues
Notebook power issues often stem from their prolific use of lithium-ion batteries, which are prone to overheating and swelling. While these issuers have mostly been resolved, it's still important to remain vigilant and on the lookout for if and when they arise.
Additionally, as batteries age, they become less reliable and might not fully charge. Another issue can stem from the AC adapter itself, because over time they get damaged and wear out. The internal wiring or the electronic parts may wear and break, causing the adapter to fail.
It's also possible to damage the power plug, or even the solder joint on the power ports motherboard connection. Typically you can't repair these issues, so it's best to replace the motherboard or have it fixed by a trained, specialized technician.
Display Issues
| Issue | Probable Cause(s) |
|---|---|
| No display output | System might be configured to use external monitor on a video port. Check display configuration in the system settings. Display's video ribbon cable has disconnected. Disassemble the notebook to reconnect the cable. Verify that both ends are properly secured. The display panel has failed. Disassemble the system. remove the display panel from the bezel, and replace it with a new one. |
| Display is dim or flickering | The user has accidentally set the brightness too low. Check the display brightness setting. The display's backlight isn't getting enough power because the inverter has failed. Replace the inverter. |
Connectivity Issues
There are a bunch of factors that affect how well the laptop/notebook communicates wirelessly. The signal will degrade the farther away you are from it, the more objects there are in the way, and the more devices are connected, so simply moving the laptop and antennae closer to each other is the most common solution.
Cooling
- Keep all air vents clear and unobstructed
- Don't place a laptop on a surface where air can't circulate under it evenly
- Consider buying special laptop cooling stands that have fans at the bottom
- Place laptops on hard, solid surfaces when the laptop cooling base isn't available. Avoid soft surfaces like a couch or a persons lap.
- Adjust processor throttling to reduce power consumption, which both extends battery life and lowers heat output.
