Laptops have become an essential part of our daily lives. As with any electronic device, laptops can develop issues over time that require repair. In my experience as a laptop repair technician, there are a few issues that seem to be the most common ones cropping up this year.
Battery Issues
The number one repair I have seen in laptops this year has been related to battery problems. As laptop batteries age and go through charge cycles, they lose their ability to hold a charge. Some common battery-related problems include:
-
Battery not charging – This is often caused by a faulty battery or AC adapter. I will run diagnostics to determine if the adapter needs to be replaced or if the battery itself is no longer functioning properly and needs to be replaced.
-
Battery not holding charge – If a battery is only able to hold a charge for a very short amount of time, it likely needs to be replaced. I recommend replacing batteries every 3-4 years in most laptops.
-
Battery swelling – Lithium-ion batteries can swell and bulge out over time. This is dangerous as it can damage the laptop chassis and other components. These swollen battery packs need to be replaced immediately.
Replacing a laptop’s battery is usually a quick and straightforward fix. I will source a replacement that is an exact match for the manufacturer and model number of the laptop. Properly disposing of and recycling old batteries is important for safety.
Display Issues
Problems with a laptop’s display are also very common. Some of the display repairs I have done most often are:
-
Cracked screens – Dropping a laptop or impacting the screen in some way often leads to cracked displays. The LCD panel itself usually needs to be replaced. In some cases, just the front glass is cracked and I can replace only that component.
-
Backlight failure – The backlight provides the illumination for the screen. Backlights can burn out over time, leading to a dim or black screen. The fix involves replacing the bad backlight.
-
Video cable failure – Inside the laptop’s hinge, there are thin cables that connect the base to the display. These can become damaged and prevent an image from showing up on the screen. The cables need to be replaced.
-
Inverter failure – Older laptops use an inverter to control power to the backlight. If this component fails, the screen will not turn on. I will swap in a new working inverter.
The specific repair procedure depends on the laptop model and type of display. Proper diagnosis is important to fix display issues efficiently.
Power Problems
Issues turning on a laptop or with the laptop randomly turning off are also quite common. Some power-related repairs I often see include:
-
DC jack repair – The DC power jack is where the AC adapter plugs into the laptop. If this jack becomes loose or damaged, power may not flow properly. I will resolder the jack or replace it completely.
-
Motherboard failure – If a laptop won’t turn on, the motherboard itself may have failed. If I cannot isolate the issue to a simpler component, replacing the motherboard may be required.
-
RAM failure – Bad memory modules can prevent a laptop from booting up properly. I will test the RAM and replace any bad sticks.
-
CPU failure – Processors can sometimes fail, especially if overheating occurs. Replacing the CPU may get the system powering back up.
Properly diagnosing no-power issues takes intricate troubleshooting skills. I use methods like trying known good replacement parts to isolate the faulty component.
Key Takeaways
-
Battery, display, and power problems are the most common laptop repairs I see.
-
With batteries, charging and capacity issues typically indicate a battery replacement is needed. Swollen batteries are hazardous and need immediate replacement.
-
For displays, cracked screens, backlight failure, and cabling issues are common. The fix depends on the specific problem.
-
With power, the DC jack, motherboard, RAM, and CPU are frequent culprits. Diagnosing the failure takes testing and troubleshooting skills.
Being able to efficiently diagnose and fix these common laptop problems takes experience. I aim to provide cost-effective, high-quality laptop repairs to extend the life of my clients’ devices. My hands-on expertise helps keep laptops from prematurely ending up in landfills.
