ADVENT LAPTOP REPAIR FAQ:
Advent
Sienna 500 Motherboard The computer won't switch on or will crash
intermittently. Some video problems also require a motherboard repair
as most video chips are fixed to the system board. Our engineers
perform component level repairs on most Advent motherboards. We can
replace resistors, capacitors, transistors and also work on the major
chips within your system. Our engineers have many years of experience
and know how to fix most motherboard faults.
Advent
Sienna 500 VGA Video Graphics
faults The system 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
Technology enables us to restore full function to your laptop in
most cases. Manufacturers and their tech support may recommend
that you spend hundreds on a new motherboards - we've got a cheaper
alternative. Examples: VGA

Power Jack Pin or Socket The laptop will not charge the battery. When
the battery power runs out the computer stops working. We repair or
replace power sockets where the power pin has broken or has become
disconnected from the motherboard. In some cases the power connector
makes a poor connection with the Sienna 500 jack. This causes arcing
which can generate enough heat to melt the Sienna 500 dc jack and the
power pin may become lose. It is best to get the Advent power socket repair before the battery is totally depleted as this can cause permanent
damage to the battery.

LCD Backlight & inverters The laptop switches on but the screen
remains dark. In some cases a faint image is visible on the Sienna 500
screen. This problem can be caused by a faulty Sienna 500 fluorescent light,
inverter, video cable or a problem on the motherboard. Specialist
tools are required to determine the exact cause of the fault.
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. We can perform repairs on some very rare
inverters. 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.

Sienna 500
Overheating We can install replacement Advent fans and
heat sink parts. In cases where the original fan is not available, we
can install substitute fans which will be equivalent or surpass the
performance of the original Sienna 500 fan.
Advent
Sienna 500 Hinge Some laptops have a problem with the hinge
becoming stiff. It becomes difficult to open and close the laptop lid.
The plastics may also be damaged by a defective hinge.
Advent
Sienna 500 Software and Drivers Viruses and improper shutdowns can lead to
the Windows XP operating system or the file system becoming corrupted.
We can recover your data and install a fresh operating system or
drivers to prevent crashes. We can also recover your data from totally
dead or unusable computers.
BIOS
update ADVENT Sienna 500
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. NEVER, NEVER, NEVER interrupt a BIOS update. Let it
finish, even if it seems stuck and takes a long time.
