Re: advent 8315 screen brightness on batteries

As I do not know that laptop I would suggest to try pressing the fn key with F8 together for brighten up and fn - F7 to brighten down

If this solved your problem please rate this solution as Solved, otherwise please ask again here

I have a Advent 8315 the turns itself off when unplugged even when its fully charged

Try removing your battery, wait 30 seconds and plug it back in and see if it powers up. If not, take your battery out, put it in the freezer overnight, take it out and let it sit in room temperature for 12 hours and then put it back in ....DO NOT put it in right out of the freezer and into the laptop ...let it warm up .... after 12 hours, try it and see if it shows 0% and charging ...if it still shows 100% charged, your battery is shot. Let me know how it goes

Advent 7111 narrow screen

If the display isn't going full screen, on that 15.4 inch TFT LCD screen, the problem is the screen Inverter, or LCD screen itself.

90 PERCENT OF THE TIME the fault is the screen Inverter.
It isn't a simple screen resolution setting that needs to be changed.


An LCD screen does not produce light by itself,

It needs an additional light source.
The additional light source is a Backlight.

A Backlight can be a CCFL, or a series of LED's.
The Advent 7111 Notebook PC uses One CCFL,

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

(Average size is 2mm Thick. Length is almost as long, as the LCD screen is in height. 2mm is close to 1/16th of an Inch )

A screen Inverter is used to convert the power from the laptop, for the Backlight, and LCD screen.

Primer over.

I don't have access to a Service Manual, for the Advent 7111 Notebook PC. I haven't had one come to my shop for repair.

I DO have years of experience at repairing laptops, and I see the Advent 7111 is just a basic laptop, as I HAVE repaired over the years.

If you wish, I can guide you step by step, in replacing the screen Inverter.

(MANY people go out, and buy an LCD screen, when the problem is a much less expensive screen Inverter. Afterwards they buy the screen Inverter. Too bad they didn't come here first)

Post back in a Comment.


[ The Advent 7111 Notebook PC is just a re-badged Quanta TW3M.
According to the source, you should see TW3M on the bottom of the laptop.

The screen brightness changes due to plug in or battery power

This is quite common actually I see it a lot. There really isn't any reason, it seems that when on batteries it trys to save power by Dimming Down, but it often just mucks up.. I always now set it via the keyboard keys. whenever I change from power adapter, to battery.

When HP laptop is pluged into power source screen goes dim

Right click on the battery icon in the taskbar, go to Power Options or something similiar. Change the plan settings for the power plan you're currently in. Check the brightness ratio for both battery and plugged in mode. This problem might come if you or someone had tinkered with the settings.
