Dell
Inspiron 4000 9100 4150 Motherboard The computer won't switch on or will crash
intermittently. Some video problems also require a motherboard repair
as most video chips are soldered onto the system board. Our engineers
perform component level repairs on most Dell motherboards. We replace resistors, capacitors, transistors and also work on the major
chips, such as the video chip, within your system. Our highly skilled engineers have over 25 years of experience
and know how to fix most systemboard faults.
Dell
Inspiron 4000 9100 4150 VGA Video Graphics
faults The computer starts up with dots or lines on the
bios or intro screen. At this level there is no other software loaded, so software problems are ruled out. Graphics are distorted, blocked or pixilated.
In some cases the system refuses to boot. Strange effects when
windows or mouse are moved on the screen. All these effects can be
caused by a faults related to the graphics chips. About 90% of
faults can be repaired, the rest are caused by damage to the
motherboard and impossible to repair. Our Advanced Video Repair

LCD Backlight & inverters The laptop switches on but the screen
remains dark. In some cases a faint image is visible on the Inspiron 4000 9100 4150
screen. This problem can be caused by a faulty Inspiron 4000 9100 4150 fluorescent light,
inverter, video cable or a problem on the motherboard.
Backlights use very high voltages and it is easy to cause damage to
the system if they are not correctly handled and installed. Our
engineers can replace the backlight lamps in most TFT/LCD screens
including the new xbrite panels. We also have access to most backlight
inverters and cables. It is very easy to destroy an expensive LCD/TFT when
removing/installing the CCFL. Our engineers are trained using broken
LCD panels before they can operate on a customer's LCD/TFT unit.

Capacitor).
BIOS
update DELL Inspiron 4000 9100 4150
Many motherboards are destroyed by incomplete or corrupted BIOS
updates. A BIOS update should only be performed if it is critically
important. Don't do a BIOS update just for the sake of having the latest
version on your computer. Ensure that your computer is stable before
performing a BIOS update. Run diagnostics to check memory, hard
drive, keyboard and video graphics. In
99% of cases a failed bios update will make the computer totally unusable
so take a backup of your software and data too. Make sure that you
have a good connection to your mains adapter and that the battery is
fully charged.
