|NOTE that this site uses software that highlights certain words in the text so that they're blue and underlined. If a post is long enough to require scrolling down to see all of it, due to whatever bug or bugs, the highlighted words DO NOT move as you scroll down the text. |
When you have scrolled down and you see a blank space where it looks like text should be, hold your mouse cursor briefly over any blue highlighted and underlined word or words that are not in the right place to make them pop into the proper place in the text.
The software seems to only highlight and underline the first occurrence of a word or words, in the entire Topic.
The mis-placed blue highlighted and underlined words can be in the post, or above or below the post.
In this case the blue words external and monitor appear below this post.
Have you, or is it possible someone else who had access to this computer...
- dropped it, or dropped anything on it, or otherwise exposed it to a physical jolt ?
- spilled liquid on it, or sprayed it with liquid, or exposed it to liquid such as rain ?
Since the video last worked properly all the time, has there been a power failure event that happened while the AC adapter was plugged in ?
Those things are the most frequent reasons something inside the laptop has been damaged.
You have NOT told us enough !
I'm assuming you have NOT installed ram that has not been installed in this computer before just before this happened.
(If you HAVE done that, if you still have it, try installing ONLY the ram in it that was installed in it before when the computer worked fine.)
Are you getting...
1. - no video at all, even BEFORE Windows is supposed to load ?
- or - 2. - you DO get normal video every time you boot the computer BEFORE Windows is supposed to load, but NO video at all AFTER Windows is supposed to load ?
- or - 3. - you DO get normal video every time you boot the computer BEFORE Windows is supposed to load, but you're getting a black screen with an error message on it instead of normal Windows graphics ?
If yes, if there are different choices you can try on the screen, have you tried all of them but you always end up at the same screen with the error message ?
For 1., if the leds on the computer are lighting up normally, try connecting an external monitor,
or if the leds on the computer are NOT lighting up normally...
In the following, the same things that apply to laptops also apply to netbooks.
Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.
See response 1:
DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.
Some laptops will display on an external monitor without you having to do anything.
If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.
