DELL LAPTOP REPAIR FAQ:

Dell Precision M4300 M2300 M4400 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 Dell motherboards. We can replace resistors, capacitors, transistors and also work on the major chips, such as the video chip, within your system. Our highly skilled engineers have many years of experience and know how to fix most motherboard 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.

Dell Precision M4300 M2300 M4400 LCD Backlight & inverters
The laptop switches on but the screen remains dark. In some cases a faint image is visible on the Precision M4300 M2300 M4400 screen. This problem can be caused by a faulty Precision M4300 M2300 M4400 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.

Dell Precision M4300 M2300 M4400 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.

Dell Precision M4300 M2300 M4400 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.

BIOS update DELL Precision M4300 M2300 M4400
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.
