The output of an Toshiba inverter is controlled by the motherboard and software. Signals from the HP motherboard determine the on/off and brightness levels of the CCFL. Motherboard failures can prevent the London CCFL from lighting the LCD screen. It is very important to determine which part has caused the backlight failure before ordering expensive London inverter boards. Most suppliers will not welcome a returned part if it does not cure your problem after supplying a correct and working part. The transformer on Toshiba inverter may burn out and cause a backlight problem. 29h RAM test completed 28h Protected mode entered safely 27h RAM quick sizing 26h Initialize int vectors 25h Initialize 237A controller 24h Test the DMA controller 23h Test battery fail & CMOS X-SUM 22h Check if CMOS RAM valid 21h Test keyboard controller 20h Test keyboard Code POST Routine Description

HP REPAIR FAQ:

HP Compaq 2400 2400 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 HP 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 systemboard faults.

HP Compaq 2400 2400 VGA Video Graphics faults
The system starts up with dots or lines on the bios or intro screen. 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 cracks on 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 always recommend that you spend hundreds on a new motherboards - we've got a cheaper alternative. Examples: VGA Video Graphics Repair

HP Compaq 2400 2400 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 Compaq 2400 2400 jack. This causes arcing which can generate enough heat to melt the Compaq 2400 2400 dc jack and the power pin may become lose. It is best to get the power socket fixed before the battery is totally depleted as this can cause permanent damage to the battery.

HP Compaq 2400 2400 LCD Backlight & inverters
The laptop switches on but the screen remains dark. In some cases a faint image is visible on the Compaq 2400 2400 screen. This problem can be caused by a faulty Compaq 2400 2400 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.

HP Compaq 2400 2400 LCD Screen
We can supply original HP and compatible replacement LCD screens. In some cases only refurbished screens are available. We don't charge extra for installing and testing screens. Screens come in various sizes (measured diagonally in inches) and resolutions(XGA, SXGA, SXGA+, UXGA...) We need the correct size and resolution to provide you with an accurate quote. While-U-Wait installation at Compaq 2400 2400 LCD Screen HP London at very reasonable prices and risk-free. 

HP Compaq 2400 2400 Keyboard
Most HP keyboards are damaged by liquid spills and general wear. We can supply or install keyboards for most HP laptops. We also repair keyboard connectors on the system board.

HP Compaq 2400 2400 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 Compaq 2400 2400 CPU in a laptop is not recommended as the cooling systems are designed to dissipate heat at normal speed.

HP Compaq 2400 2400 Overheating
We can install replacement HP 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 Compaq 2400 2400 fan.

HP Compaq 2400 2400 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.

Compaq 2400 2400 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.

HP Compaq 2400 2400 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.

HP Compaq 2400 2400 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.

HP Compaq 2400 2400 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 HP Compaq 2400 2400
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 HP Compaq 2400 2400
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.

Q. Do you supply spare parts?

A. No. We are in the process of launching a new website dedicated to supplying spare parts to repair centres and end users.

Common Laptop Issues
:


A lot of HP systems are being sent to us for software problems caused by Viruses. It is essential to protect your HP laptops using the latest versions of anti-virus software and update the pattern files at least once a week. Most London anti-virus systems will automatically check if updated pattern files are available - always elect to get the updated files when asked. Most London viruses will attempt to modify the system registry - use registry protection to prevent unwanted modifications. The field-effect transistor uses either electrons or holes for conduction. The four terminals of the FET are named source, gate, drain, and body. On most FETs the body is connected to the source inside the package. A semiconductor is a material that has the properties of both conductors and insulators.
