hey there!

I recently purchased an HP DV6 laptop with ATI Mobility Radeon Graphics. My laptop's screen tends to fade and then lighten up again and this happens randomly. It's not a frequent occurrence but i've noticed it generally happens when my laptop is not connected on AC power.

do u guys think its a problem or a problem that will occur?

Any help in this regard will be appreciated. Needless to say u guys are doing a wonderful job.

Regards

It sounds like it's due to power fluctuations.

If it only happens when the laptop is running off the battery, is at a certain percentage remaining?

Try removing the battery and plugging in the charger.

Use the laptop like this for a while and see if the problem presents itself.

If it works properly, then that will give more evidence to my theory that it's due to power fluctuations.

On battery, my DV9000 dims the screen backlight after a few minutes of inactivity, to conserve power.

When you say it happens randomly, does it ever occur when the laptop is in active use?

So it's more a case of becoming oddly bright, then going back to normal rather than going dim then coming back to normal? If it does this in the course of normal use, typing documents, web surfing etc, it doesn't sound right, and it would probably be best to get it seen to under warranty.
