    thanks mike, it works fine on an external monitor. its out of warranty so i was thinking of opening it up and seeing if there are any loose connections to the screen. i read on some of the other topics that that could be the problem. thanks for your help

Hi,
i,d suggest trying the laptop on an external monitor firstly.
this will eliminate motherboard fault.
then if it displays fine on the external monitor.
possibility of Faulty Inverter Or CFL Tube.

    Hi,

    No problem, if you search for a service manual. you can usually download one for about £3. ** Invaluable **

    this will show you any hidden screws et,c. as there are usually screen masks. ( small sticky pads ) covering screws et,c.

    Also check that the screens shut-off plunger. ( lid close switch )

    Has not stuck in or jammed.



    Regards Mike @ compurepair.

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.

http://www.laptoppowerjacks.co.uk/advent-inverter/advent-7111-7107-8315-lcd-screen-inverter-as023217127-iv09140t-lf.html

Primer:

An LCD screen does not produce light by itself,

http://solutions.3m.com/wps/portal/3M/en_US/Vikuiti1/BrandProducts/secondary/optics101/

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,

http://www.screencountry.com/index.php?section=products&model=7111&brand=Advent&size=

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)

[ 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.

Advent 7113 doesn't detect mains


It is highly posible that the jack in your laptop where you plug the main dapter is making a false contcat due to a problem in the welding of its connectors to the main board or to corrosion. Check if the rentral plug is not loose or if the plugs seems to be loose when you plug it.
If it is so, you need some expert technician to solve the problem by re weilding it or replacing it.

Laptop gone dark


This sounds like a burned out backlight lamp.  Had that happen to a Mac laptop used at work:  all the boot-up LEDs and sounds occurred, but a dark screen.  It was fixed promptly by our computer guy, who is pretty amazing at fixing computers.  So all I can tell you is that it shouldn't be a particularly expensive repair.
