This document is intended only as a guide to resolve various issues with laptops and/or notebooks with mobile Intel® processors. Ultimately, your laptop/notebook system manufacturer or mobile motherboard manufacturer may have the very latest information to help resolve your issues.
Important Note: Disassembling, assembling, upgrading and troubleshooting computers should be performed only by a computer professional since the electronic devices may cause serious damage to the installer, the system and its components if it is done improperly. Before attempt to disassemble or assemble notebook computers, carefully review the documentation specific for the laptop computer and its related components. Make sure that you will not be voiding the warranty of the system by opening the laptop computer or replacing any of the components in the notebook computer. Lastly, make sure to follow Electrostatic Discharge (ESD) procedures.
- Determine if the system worked before.
- Determine if there have been any recent changes. Often, recent changes are the cause of the problem. If recent changes have been done, verify the configuration of those changes. If you installed a new device, suspect that the new device is causing the problem. This can be done by replacing the suspect device with a known working device and trying that device in a known working machine.
- Check the LCD panel brightness and contrast controls.
- If you are trying to run the laptop from battery, try running the laptop from the AC adapter. If it works with the AC adapter, you have a problem with your battery or charging system. Contact your laptop manufacturer or vendor.
- Use a voltmeter or an AC tester to confirm that there is adequate AC voltage at the wall outlet.
- An AC adapter can be tested with a voltmeter (measuring DC voltage) whereas the output should be +/-.3 volts.
- Check for shorts and overloads inside computer by removing nonessential items such as PC cards and drives, just to see if the machine attempts a Power-On Self Test.
- Make sure that the laptop computer supports the processor that you are installing including type of processor, speed and voltage.
Note: An Intel® Core™2 Duo mobile processor does not work in a system that is made for a Intel® Pentium® M processor and vise versa. Lastly, you will need to check if there are any jumpers or Dip switches that need to be configured on the laptop computer including those that indicate the speed of the processor.
- If you just installed a processor, make sure that you have inserted the processor completely in the socket and that the processor is oriented correctly. In addition, make sure that the screw that locks the processor in place is adjusted correctly. Check the laptop service manual for the correct orientation.
- Swap any detachable RAM and the processor with known good replacements one at a time. If suspect one of these components, try it in another laptop computer. In addition, if you installed RAM into the notebook computer, make sure that the RAM is on the tested memory list for the laptop computer.
- If the problem still exists, you need to contact your notebook vendor or manufacturer.
