I am facing a problem with my Laptop LED display. Whenever I turn on my laptop the led screen shows nothing while windows load because I can hear startup sound of it. Then I force shutdown my laptop and turn it back on and led works normally. It only gives me a problem when I put my PC to sleep or when I turn it on. Specifications of my laptop are:
• Lenovo G510
• 6GB RAM
• 1 TB hard drive
• 2GB AMD Radeon Graphics card.
• 2.50 Ghz Processor
I applied some solution but it didn't work
• Press the power button for 10s after taking out the battery.
• Cleaned Ram.
• Serviced my Laptop.
Is this a hardware problem ? What should I do ?
Laptop LED does not turn on after sleep or at startup
