You may encounter many problems on your laptop, the cause of which can be software or hardware. Troubleshooting steps must be systematically followed to detect the cause of the problem and repair it. There’s very little difference between troubleshooting different laptops, as the basic design of all of the laptops is same, even if one model uses an Intel CPU, another an AMD, a third a PowerPC and a fourth a low power Transmeta.

Laptop does not start after being turned ON:

This problem mainly occurs due to improper supply of power. It can also be a result of overheating. In order to solve the problem you may perform the below steps:

  1. If you are using a battery, inspect it to verify whether it needs recharging. If it does, recharge the battery after fully discharging it first.
  2. Check the connection of the power cable to the socket. The connection must be tight.
  3. Laptop consists of external power indicator which can be checked in case there are power related problems.
  4. Check the AC adapter. If the light on the AC adapter is not ON, it is not working properly and must be replaced.
  5. If the power indicator shows a blinking orange light, the laptop has probably shutdown because of overheating.
  6. Check the output vent of the laptop to see if the Fan is working.
  7. See if there is dust covering the output vent.
  8. Clean the dust carefully with a soft dry cloth.
  9. Allow the laptop to cool down and then restart it.

CTRL + ALT + DEL does not work:

  1. Press the power button and turn off the laptop.
  2. Restart the laptop and check the keyboard lights to see if the keyboard is recognized. Press the NUM lock or CAPS lock key to verify this.
  3. If the keyboard is not being recognized, contact the manufacturer to solve the problem or connect another compatible keyboard to the laptop.
  4. Check ‘Event Viewer’ details to see if an error has been logged.
  5. Run the Antivirus Program to detect a virus or Trojan horse in the system.

Laptop Keyboard gets wet:

  1. Shutdown the laptop and remove the battery.
  2. Disassemble the laptop.
  3. Unplug and remove the keyboard.
  4. Let all the liquid drain out of the keyboard.
  5. Clean the keyboard with cotton swabs.
  6. Clean the underside of the keys with a blower. Be careful to hold the can in the proper angle.
  7. Turn the laptop upside down very carefully, without damaging the display. Leave the laptop in this position for at least 48 hours before turning it on.
  8. Plug in the keyboard and check if it is working.
  9. If the keyboard does not work, it will have to be replaced.

CD/DVD problem:

Sometimes you may get an error like ‘drive is not accessible’ or ‘device is not ready’, when you try to access your CD or DVD drives. This may occur even if the ‘Device Manager’ does not show any fault.

  1. Ensure that the connection to the drive is secure and the disk is properly inserted in the drive.
  2. Check the surface of the disk for dirt or abrasions.
  3. Clean the drive with a cleaning disk.
  4. Try playing other disks in the drive. If no disk plays there is a problem with the drive.
  5. Try to access the drive after restarting the laptop.

Power failure:

Power failure occurs when the battery is not properly installed. If the battery is working properly and still there is a problem then there is a main board failure. (Avoid replacing the laptop battery in a hurry). Perform the following steps.

  1. Check the power adapter.
  2. Check whether the LED on the power adapter is ON. The user can check this by unplugging the power adapter and simply plugging in the power outlet.
  3. Ensure that the little LED status lights ON the laptop light up with the power plugged in.
  4. Check the battery. Check the switch.
  5. Check the Motherboard and power supply.

Battery running down very fast:

When the laptop battery is running down very fast, the screen dims, CPU slows down and when the hard drive is not in use it spins down then performs the following steps:

  1. Make sure the aggressive power saving modes in software is enabled. The power saving mode is accessed through control panel or the manufacturer’s icon.
  2. Set the onscreen alarm for estimating the level of remaining battery life.
  3. Change the default settings to a lower level if possible which will give you time to save your work and shutdown before the laptop goes into Hibernation.
