Device is much warmer than it should typically be.
With the laptop open, after following our disassembly guide, use a can of compressed air to un-clog the metal heat sinks and plastic vents. If any dust still persists, unseat it to a point where it can be manually removed without bending or putting too much pressure on any internal parts of the laptop.
This method of may require that you buy a replacement cooling fan. After following this model’s disassembly guide, if the user finds that the fan is not being stalled or blocked by an alarming amount of dust, it may be that the fan has simply broken and must be replaced.
It may be that your machine simply has too much software running at any given time. If your laptop is usually sluggish or running warm, consider reinstalling your operating system or uninstalling some software that is not used too often.
The device does not respond to the power button.
There’s a possibility that there may be an issue with the RAM stick(s) inside of your laptop. Consider re-seating or replacing your RAM by following our RAM replacement guide.
If your computer does not boot into Windows or whichever operating system you normally use, attempt to boot into your BIOS by pressing F2 when the machine attempts to boot up. This should (hopefully) launch the computer’s BIOS, in which you should be able to view the connected peripherals. If the hard drive is not listed, it may either be broken or disconnected. In either case, replacing the drive and installing a new operating system should fix the issue.
The battery inside your machine may either be completely discharged or not working correctly. Consider plugging the charger into the laptop and allowing it to charge for a considerable amount of time. If the machine will not turn on, after removing the charging cable, the battery may be disconnected or non-working. If the machine will turn on, but only when connected to power as well, consider replacing the battery.
The laptop is unable to charge.
If your laptop does not charge using the included charger, your charging cable may be defective. If possible, try using the charger on another laptop model or try using a different charger on your machine. If the problem can be traced back to the charger itself, it will have to be replaced.
If the port itself is broken, the machine will not respond to any charge from any working charger. The connector will most likely be loose or broken if this is the case. To fix this issue, the motherboard will have to be taken out and have a new charging port soldered on.
If none of the issues above seem to identify the problem, then the circuit controlling the charging may be broken and would need to be fixed by a professional. In addition, replacing the motherboard itself should fix this problem.
The keyboard or mouse is not responding.
Keyboard problems may be caused by either hardware or software issues. To troubleshoot the keyboard, attempt to boot into the BIOS using the F2 key when the computer starts up, to ensure that at least one key works and that the issue is software-related. If that’s the case, reinstall the keyboard drivers within your operating system. If not, either re-seat the connector on the motherboard or replace the keyboard module entirely.
If there is no mouse movement at all, there will most likely be either a connection or hardware issue if the problem is not resolved by re-installing drivers. Try to re-connect the cable connecting it to the motherboard, or replace it with a new trackpad module.
A wired connection may work, but wireless connections may not.
Wireless connections may fail due to a faulty wireless card. If updating the drivers doesn’t seem to fix the problem, and no wireless connections at all work, consider replacing the wireless adapter.
Computer may fail to start, error messages may appear.
The CMOS battery may be dead and needs to be replaced if a message appears regarding BIOS settings or CMOS settings. Make sure the laptop is unplugged and powered off. From here you need to remove the battery on the underside of the laptop. Follow our CMOS battery replacement guide.
There might be a problem with your hard drive or the operating system installed on your hard drive. To fix this problem, consider replacing your hard drive, or reinstalling your operating system.
A part on the computer screen appears to be darker or completely black while the remainder of the screen has full color, or multiple spots on the computer fade in and out of phase causing a “glitch”.
Can be caused by a potential bad display panel. Along with the bad display, multiple connections could be off or have a loose connection. Bad video drivers are known for causing some pixels to remain in place and having bad video hardware can cause the issue to increase and more pixels can become faulty and or “glitchy”. Consider reinstalling video drivers, and if that doesn’t fix the problem, replace the display panel.
Usually if there are one or few dead pixels, it is a panel issue. A stuck pixel means that this pixel only remains one color at all times on the screen. For example if you have open a blue picture and one square on the picture is green, you have a stuck pixel and or dead pixel. In the case of “stuck” pixels, it may be possible to temporarily fix the problem by gently applying pressure on the screen next to where the pixel is. If not, this issue can be resolved simply by replacing the entire display panel.
If there are intermittent display issues when using the laptop, the potential issue may lie within the hardware or video drivers. The first step would be to consider reinstalling your video drivers. This way, if this solves your display issues you do not have to replace the hardware. If this does not fix your issue, your next step would most likely be replacing your motherboard in order to fix the intermittent display issues.
