ACER REPAIR FAQ:
Acer
Travelmate 7720 730 7220 C300 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 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 systemboard faults.

LCD Backlight & inverters
The laptop switches on but the screen
remains dark. In some cases a faint image is visible on the Travelmate 7720 730 7220 C300
screen. This problem can be caused by a faulty Travelmate 7720 730 7220 C300 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 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 7720 730 7220 C300 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 7720 730 7220 C300 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 7720 730 7220 C300 fan.
Travelmate 7720 730 7220 C300 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.

Travelmate 7720 730 7220 C300 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).
Secondhand
or Used ACER Travelmate 7720 730 7220 C300
Buying a used laptop is a risk. You may find that the battery
does not accept a full charge or the laptop is unstable. Most
secondhand sellers consider any laptop that boots into Windows as a
working machine, even if it keeps crashing every five minutes. We
strongly advise customers against buying used laptops with a
DOA warranty as some faults are not immediately apparent.
