COMPAQ REPAIR FAQ:
Compaq
Presario 2521ea 2529ea 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 Compaq motherboards. We replace resistors, capacitors, transistors and also work on the major
chips within your system. Our highly skilled engineers have many years of experience
and know how to fix most motherboard faults.

LCD Backlight & inverters
The laptop switches on but the screen
remains dark. In some cases a faint image is visible on the Presario 2521ea 2529ea
screen. This problem can be caused by a faulty Presario 2521ea 2529ea 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. We can perform repairs on some very rare
inverters.Our engineers are trained using broken
LCD panels before they can work on a customer's LCD/TFT unit.

Presario 2521ea 2529ea 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 COMPAQ Presario 2521ea 2529ea
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.
BIOS
update COMPAQ Presario 2521ea 2529ea
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.
