Question about Gateway 450ROG Notebook

1 Answer

Almost no vide

My gateway M-6834 apparently has no problems at start up, there's the sound of windos vista and the hard drive light shows "normal" activity. However displays a very (almost unperceptible) image. I can hardly see the desktop screen (just some elements actually), but not the mouse pointer either. Any advice you can share with me about how to pinpoint the problem and its possible solution? Thank you very much in advance guys.

Your display backlight is not working, so even though the display is working you can only see it very dimly. The usual cause is failure of the inverter, a small circuit board inside the display that makes power for the backlight. It's also possible the backlight itself has failed, but the inverter is much more likely. Changing the board is not difficult, it just has a couple of cables that plug in. The bigger problem is usually finding a replacement, and then getting the display open. There are several online sources for replacement inverters, and they usually offer instructions for your particular computer. Use Google or your own favorite search engine to look for "<insert computer model here> inverter" and you'll probably find one.

Hi i tried to unistall the windos vista on my laptop but it didnt continue the uninstallment is not completed? when i open my computer i saw only a blinking(- )dash


Normally, operating systems are un-installed by either

1) Installing a new one and over-writing the first.
2) Formatting the hard drive

The thing is what is the outcome you wanted when uninstalling Vista ?

If its to install an new operating system, then install that operating system. It will, as part of its function, format and thereby stripping all data from you hard drive.

Gateway m-6834 battery light blinking red and won't turn on


Either:

A) Bad battery

Easy to check, take it out and try to boot. If yes. Get a new battery.

If no.

B) Bad AC adapter

Does the power brick have an LED on it? Is it on. Even if it is it may not be putting out voltage. If the cord gets bent alot it can break inside so it looks normal. If you or some you know has a MultiMeter , have them check the voltage.If you know someone with the same laptop, try theirs. If it works get a new one.

C) Broken connector inside laptop
If a known working AC adapter doesnt work there could be a broken connector inside that needs to be resoldered or the power subsystem on the board could be fried.

This is either an operating system failure or hard drive failure. Start by reloading a fresh operating system (Vista) with your recovery or operating system disc. If you have any problems during or after the install, then it's the hard drive and will need to be replaced.
