ACER LAPTOP REPAIR FAQ:
Acer
Travelmate 2450 620 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 Acer 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.
Acer
Travelmate 2450 620 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 Travelmate 2450 620 jack. This causes arcing
which can generate enough heat to melt the Travelmate 2450 620 dc jack and the
power pin may become lose. It is best to get the Acer 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 Travelmate 2450 620
screen. This problem can be caused by a faulty Travelmate 2450 620 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 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 work on a customer's LCD/TFT unit.

Travelmate 2450 620 Keyboard Most Acer keyboards are damaged by liquid
spills and general wear. We can supply or install keyboards for most
Acer laptops. We also repair keyboard connectors on the system
board.

Travelmate 2450 620 CPU problems Intel CPUs hardly ever go wrong, but are
very difficult to diagnose. Some will crash on rarely used
instructions and at certain temperatures. Unfortunately, hours of
testing can be in vain if the problem instruction isn't executed.
Most CPU failures are cause by BGA problems. Overclocking a Travelmate 2450 620 CPU in a laptop is not recommended as the
cooling systems are designed to dissipate heat at normal speed.

Overheating We can install replacement Acer 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 Travelmate 2450 620 fan.
Acer
Travelmate 2450 620 Hinge Some laptops have a problem with the hinge
becoming stiff. It becomes difficult to open and close the laptop lid.
Travelmate 2450 620 CD/DVD and floppy drives Our engineers can repair or replace these
drives. We have a lot of drives in stock and the work can be carried
out very quickly.
Acer
Travelmate 2450 620 Charging problem Charging problems can be due to
batteries nearing their end of life, power supply problems or failed
components on the motherboard (FET, MOSFET, Transistor, Diode or
Capacitor).
BIOS
update ACER Travelmate 2450 620
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.
