Hi there,

Does the brightness change when you plug the AC adapter into the Laptop? If not, can you change the brightness on the keyboard? Also, check the bios. Make sure there is no settings within the bios that allows you to change the power schemes. One last thing, Make sure you have the latest Bios revision. Go here to check and download if necessary

Thanks to you both. I found this description (lcdscreen.com) on causes of dim screen...
"The cold-cathode fluorescent tube(backlight) has gone out or the inverter is bad. Nearly 75% of the time, if your screen is dim, the inverter is no longer working correctly. The inverter powers the backlight in the notebook screen. We suggest that you replace your inverter first, before considering replacing your notebook screen. "

But - I connected an external monitor and it was dim, too. So it can't be the laptop's inverter or screen, eh? User swears no display settings were changed.
