I took apart my vaio laptop (I have had experience with Vaio Laptops) and put it back together twice trying to figure out why the screen is blank and also the indicator (LED indicator) that looks like a cup does not lite up. Everything else works. The screen for the laptop is fine, its just that the laptop is 3 to 5 years old. The only reason I took it apart is because the ram had 512MB worth of ram and it only indicated that it has 256MB. I noticed it awhile ago, but it pissed me off so I took it apart and put it back together, I found out the reason the ram wasn't working. The ram needed to have something being forced on it with the lid closed, so it will reconize it. Any suggestions.
