Tips To Fix Black Screen Error in Sony® Laptop
What are the various ways to fix the blank screen error in Sony laptops?
The blank screen error in Sony laptops may occur due to the problem with the battery. The discharge of battery causes the laptop to shut down. If this process continues, the battery would continue to drain the charge even if you are using AC adapters. So, first of all, charge the battery at least for two hours and then try booting the laptop. The black screen error may also occur due to some problem with the mother board. If anything goes wrong with the mother board of your laptop, it will cause some problems while working. Since there is a problem with the mother board, the laptop would not be able to boot. So, if you have a doubt that your mother board is having some problem, get it checked by some technician and if required, replace the mother board. The problem may occur because of some problem with the button cell situated on the mother board. This button cell helps the mother board to control its functions. In any laptop, the voltage of this button cell should be above a certain range. Then only the Sony laptop would work normally. So, if you encounter some problem, check that the voltage of the button cell is around 2.5 to 3 volts.
Discussed below are some points that would help the users to know about the reasons for the blank screen and different ways to fix the problem:
While working on a computer or laptop, any problem with the display is a very big issue i.e. the computer screen remains blank, although the monitor's power light is on. This perplexing and frustrating problem is somewhat difficult to diagnose. Sometimes, this problem needs special tools. While working on the problem, remember to turn off the computer after each step and never work inside the computer case with the power turned on.
It is a hardware problem or it can be a BIOS setup problem. It can happen in many ways - Computer hardware might not be installed correctly; mother board's jumpers are set incorrectly; computer or its peripherals have been shorted out; or it can occur due to some other mechanical problem. Though these could some of the reasons, sometimes it is difficult to pinpoint the exact reason. When the display stops working, the remedies should be worked out one by one.
Check the cables of the system and make sure that they are well attached to the computer at the back. Remove the case cover and make sure all cables inside the computer are firmly attached. Make sure all cards such as ISA and PCI and dynamic RAM memory cards are firmly seated. Make sure that the CPU is not hot. If the computer is a newly built one, check all the mother board jumper settings. Review all the accessory wire connections. Verify that CPU and power supply fans are running. After unplugging the computer, remove all PCI and ISA cards. Reinstall the video card and disconnect the hard drive cable. Plug in the keyboard video cable and power cable. Restart the computer. If the error still persists, make sure the mother board is not in contact with the computer case. The video card, video cable, or monitor may be malfunctioning. Change it. Remove the CPU and reinstall. Reset the BIOS using the instructions in the manual.
