COMPAQ REPAIR FAQ:
Compaq
Presario R4065ea R4218ea 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 Compaq 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.

Presario R4065ea R4218ea 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 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 Presario R4065ea R4218ea jack. This causes arcing
which can generate enough heat to melt the Presario R4065ea R4218ea dc jack and the
power pin may become lose. It is best to get the Compaq power socket repair before the battery is totally depleted as this can cause permanent
damage to the battery.If you get a electrical burning smell from near the power connector then disconnect the adapter immediately. The arcing is burning away the motherboard.

LCD Backlight & inverters The laptop switches on but the screen
remains dark. In some cases a faint image is visible on the Presario R4065ea R4218ea
screen. This problem can be caused by a faulty Presario R4065ea R4218ea 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 work on a customer's LCD/TFT unit.

Presario R4065ea R4218ea 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.
Overclocking a Presario R4065ea R4218ea CPU in a laptop is not recommended as the
cooling systems are designed to dissipate heat at normal speed.

Hard Drive Faulty hard drives can cause data loss and
stop your laptop from booting into Windows. We can replace faulty hard
drive and attempt to recover your data. After installing the new
drive, our engineers perform a thorough disk test to ensure that your
data is as secure as possible.

Presario R4065ea R4218ea 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).
