Charger Not Working

2023-07-08T06:32:35Z

Here are the steps to determine if your laptop charger is broken or functional:

Change the power outlet: Plug the charger into a different power outlet that is known to be working properly. If your laptop charges when connected to a different outlet, the issue is likely not with your computer or charger.

Check for charging lights: Many laptops have a light somewhere on the device that indicates whether it's receiving power. It could be above the keyboard, on the side, or back of the unit. Sometimes, the charger itself may have a light. If the power adapter or the laptop feels unusually warm, wait until it has completely cooled down before connecting it to a power source. Inspect the power adapter: Examine the entire length of the power cord for any tears, dents, or worn-out insulation. If you notice any flaws or if the connector is warped or smells like burnt plastic, the cord is likely faulty. Bring your laptop to us and request to test it with a working charger. If a working charger successfully charges your laptop, you may need to order a replacement adapter.

If you are using a newer laptop model with USB-C charging, ensure that your power adapter is connected to the correct port on the laptop. Check your warranty before replacing any parts, as the cost of the adapter may be covered.

Check the power jack on the laptop: When the charger is properly connected to your laptop, it should not be loose or fall out of the jack. If the connection feels loose, there may be a bent pin inside the power jack or the entire jack could have become loose from the motherboard. Take your laptop to a repair shop for a proper diagnosis. Bent pins and other power jack issues are model-specific. You can look up repair instructions for your specific model online, but the repair usually involves purchasing a new power jack and soldering it onto the motherboard. This could void your warranty.

Start up your laptop without a battery: Shut down the computer, remove the battery, and connect the computer to a power source. If the laptop wasn't powering on before but works without the battery, you may need a new battery. Alternatively, there might be another method to fix the problem, or your battery may be completely drained and require replacement. If your laptop's battery is not removable, skip this step and try the methods below before taking your laptop to a computer repair store.

If none of these steps resolve the issue, it's recommended to seek professional assistance to diagnose and fix the problem with your laptop charger.

Updating BIOS

2023-07-07T07:17:51Z

The computer's BIOS (Basic Input/Output System) is software that acts as an interface between the computer's hardware and the operating system. It contains basic information about the computer's components and determines their operation. BIOS may need to be updated for various reasons, such as the following:

Hardware Compatibility: Newer hardware components like processors, graphics cards, or memory modules may require a BIOS update to function properly in the computer. The update may include new features, fixes, or improvements for hardware compatibility.

Security: BIOS updates can include security patches that protect the computer from potential attacks or vulnerabilities. Updates can also enhance the computer's security features or improve its protection.

Performance: BIOS updates can provide performance-related improvements, such as faster boot times or better hardware management. Updates can also optimize power consumption or increase the computer's efficiency.

Errors and Issues: If there are any BIOS-related issues, such as hardware recognition or functionality issues, a BIOS update can help resolve these problems.

UEFI and BIOS are two different types of motherboard firmware used during startup to initialize the hardware and load the operating system. They also determine the device boot priority and allow users to customize hardware and software settings.

Both firmware types serve the same purpose, but UEFI is newer and offers more customization options and features.

UEFI stands for Unified Extensible Firmware Interface. Its purpose is to store all data about device initialization and startup in an .efi file, which is kept on a special disk partition called the EFI System Partition (ESP). The ESP also holds the bootloader responsible for booting the operating system.

UEFI was primarily created to overcome the limitations of BIOS and reduce system boot time. UEFI uses the GPT partitioning scheme and supports much larger drive sizes.

Additionally, UEFI provides better security with the Secure Boot feature, which prevents unauthorized apps from booting. However, the downside is that Secure Boot prevents dual booting because it treats other OSes as unsigned apps.

UEFI runs in 32-bit or 64-bit mode, allowing it to provide a graphical user interface.

Thermal paste replacement

2023-07-02T08:25:12Z

Computer processor thermal pastes are usually replaced for two main reasons:

Improved heat conductivity: The processor thermal paste is a substance that is applied between the processor and the cooling system. Its purpose is to enhance heat conductivity. Over time, the thermal paste can dry out, harden, or lose its effectiveness, which diminishes its ability to transfer heat from the processor to the cooling system. This can lead to processor overheating and reduced performance. Replacing the thermal paste with a new one can improve heat conductivity and ensure that the processor stays sufficiently cool.

Maintenance and upkeep: Replacing the processor thermal paste can be part of general maintenance and upkeep for a laptop computer. Regular cleaning and thermal paste replacement can help keep the laptop computer in working order and prevent potential issues such as overheating or decreased performance.

It's important to note that replacing the processor thermal paste requires precision and carefulness. If you're unsure of your skills or don't feel confident, it's recommended to seek assistance from a professional.

Replacing processor thermal pastes in a laptop computer is a fairly straightforward process. Follow these instructions:

First, make sure you have a new processor thermal paste that is compatible with your laptop's processor.
Shut down the laptop computer and disconnect the power cord and battery. This is important for safety reasons and to prevent any accidental damage.
Locate the processor cooling system on the bottom of the laptop computer. It is usually under a protective cover or behind a door on the back of the computer. If you're unsure, you can refer to your computer's manual or search online for more detailed instructions.
Once you've found the processor cooling system, carefully remove it. It is typically secured with screws or clips. If necessary, you can use a screwdriver or another suitable tool.
With the processor cooling system removed, you'll be able to see the processor and the old thermal paste. Use a soft cloth or alcohol wipes to carefully clean off the old thermal paste from the processor and cooling system. Make sure to clean off any residue thoroughly and allow the surface to dry before proceeding to the next step.
Once the surface is clean, take the new processor thermal paste and apply a thin layer to the surface of the processor. You can use a specialized thermal paste application tool or something like the corner of a small plastic card. Ensure that you apply an even, thin layer for efficient heat transfer.
Reinstall the processor cooling system and secure it tightly with screws or clips. Make sure it fits snugly in place for proper heat transfer.
Now you can reassemble the computer, remembering to reconnect the battery, plug in the laptop's power cord, and start it up normally.

Windows does not start

2023-06-15T07:15:57Z

What to do when Windows doesn't start:

If you're trying to start your computer and Windows refuses to boot, what should you do? "Windows doesn't start" is a common issue with various possible causes. Here are some troubleshooting steps:

First steps: Has anything changed?

Think about any modifications you've made recently to your computer. Have you connected any new hardware, updated any new device drivers, or opened the computer case and made any adjustments? A problematic driver, unsuitable hardware, or an unintentional disconnect from something within your computer could all be the culprits.

Here are some specific examples of what you might have done:

You installed a new driver for your printer, but the driver was not compatible with your printer model.
You connected a new USB device to your computer, but the device was not properly supported by your operating system.
You opened the computer case and accidentally disconnected a cable.

If the computer doesn't start at all:

If your computer doesn't start at all, make sure it's connected to a power source and the power connector is secure. For a desktop computer, check that the power switch at the back - the power supply - is set to "On." If it still doesn't start, it's possible that you accidentally disconnected the power cable inside the computer. If you haven't disconnected anything inside the computer, the power supply may be faulty, and in that case, it needs to be replaced.

Also, remember to check your computer monitor - if your computer seems to be booting up, but the screen remains black, ensure that the monitor is powered on and the cable connecting it to the computer case is securely attached at both ends.

Computer starts but displays "No bootable device":

If your computer starts but displays a black screen with a message like "No bootable device" or another "disk error" message, it means your computer is unable to boot from the hard drive where Windows is installed. Access your computer's BIOS or UEFI firmware settings and check the boot order setting to ensure the Windows boot sequence is configured correctly.

When your computer starts up, it tries to boot the operating system from the devices listed in the boot order. If the boot order is incorrect or if the bootable device is faulty, you may receive an error message stating "No bootable device." To fix this, you need to check your computer's BIOS or UEFI settings.

Start your computer and look for the key or key combination that opens the BIOS or UEFI settings. Typically, this key is Delete, F2, F10, or Esc. If you're unsure, consult the computer manufacturer's website or user manual.

Once you're in the BIOS or UEFI settings, locate the "Boot" section. Here, you should see a list of boot devices and their order.

Ensure that the hard drive where Windows is installed is set as the primary boot device. You can change the boot order using the arrow keys or function keys indicated at the bottom of the screen. Move the hard drive above the boot order list so that it boots first.
Save the changes you made in the BIOS or UEFI settings and restart your computer. Now your computer should attempt to boot Windows from your hard drive.

If these steps don't resolve the issue, you may need to check the hard drive or reinstall Windows. Windows boot problems can be frustrating and challenging to troubleshoot. These were a few different reasons why your computer may not start, and we provided some tips on how to resolve the issue. We understand the frustration and difficulties caused by Windows boot problems, and we're here to help. Always remember to check all cables and devices before attempting any other solutions. If the problem persists, don't hesitate to seek further assistance!

If the previous steps didn't solve the issue, here are a few additional suggestions:

Safe Mode: Try booting your computer in Safe Mode. This mode starts Windows with only the necessary drivers and services, which can help identify and resolve software conflicts or issues. To access Safe Mode, restart your computer and repeatedly press the F8 key (or another key specified by your computer manufacturer) before the Windows logo appears. From the Advanced Boot Options menu, select Safe Mode.

System Restore: If you recently installed new software or made changes to your computer settings, a System Restore can revert your system back to a previous working state. To perform a System Restore, boot your computer in Safe Mode and access the System Restore tool through the Control Panel or by searching for "System Restore" in the Start menu.

Startup Repair: Use the Startup Repair tool to automatically fix certain startup issues. You can access this tool by booting your computer from a Windows installation disc or USB drive. Follow the on-screen prompts to initiate Startup Repair.

Check for hardware issues: If software-related solutions haven't resolved the problem, it's worth checking for hardware issues. Ensure all hardware components are properly connected and seated in their slots. If you recently added new hardware, try removing it to see if the computer starts normally.
