Question about Fujitsu Siemens LifeBook S7020 Notebook

2 Answers

I have a Fujitsu Siemens Lifebook s7020 with no backlight. The display is showing everything but it's hard to see because there's no backlight. Everything is also fine with an external screen. I have a spare s7010 laptop. I have already changed the entire screen. Problem stays the same (normal display but no backlight). So I think the problem is on the main board. Maybe the powersupply toward the inverter/backlight?

That's right. You have good answer. Mainboard to LCD = have two connection, to back in the LCD (coaxial cable) and to inverter video (for backlight). You must replace new one of inverter video. For spare part, ask to dealer where you buy it.

The Inverter board must be tested and eventually replaced. The inverter is the small board located at the base of display. This is connected to one side to the backlight lamp, to which supplies AC high voltage, and on the other side to motherboard, where receives DC voltage.

Inverter contacts to otherboard and to lamp must be tested , using a multimeter to read volts. The inverter is an AC board, and for safety reason the test must be done by a trained repairer.
If the inverter is OK check the contacts to motherboard and wiring harness to motherboard..

Also ensure that light is not just dimmer because energy save mode is on, or because the laptop is running on batteries.

How do I replace the fan in my Fujitsu Lifebook S7020 or find instructions to do so?


I found this in my archive, it is not the S7020 but it is the S7010. I believe they have the same case design, so this will most likely work for you. It is a aolor picture guide to the disassembly of the laptop.

Lifebook S7020 No backlight


Take the laptop to your nearest computer repair shop to have the inverter replaced.

It is situated underneath the LCD panel and converts DC electricity to AC to power the backlight of the LCD.

This shouldnt cost much to replace - around £40/£50
