Ad4u Limited are the leading independent UK laptop repair centre for out-of-warranty Dell Studio, Inspiron and Latitude computers. We have access to most Dell laptop spare parts therefore our laptop repairs are fast, efficient and reliable. Most repairs are completed within three days. Our engineers have over twenty years experience in computer maintenance and have received expert training from manufacturers like IBM. We have also maintained desktops and laptops for some of the largest corporate companies in the UK.

Repairs we perform:

• Latitude C640 and C540 Motherboard
  The laptop 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. Only a few laptops have a separate video card. Our engineers can perform component level repairs on most Dell motherboards. We can replace resistors, transistors and also perform work on major chips within your system. A lot of system board failures are caused by the motherboard bending when the laptop is moved. Have a look at our motherboard repair page. Our engineers have many years of experience and know how to fix most systemboard faults.
   
  

• Latitude C640 and C540 Power Socket
  The laptop fails to switch on and will not charge the battery. We repair or replace power sockets where the power pin has broken or has become disconnected from the motherboard. In most cases the motherboard needs to be removed from the system to complete the work. Sometimes the power connector makes a poor connection with the Latitude C640 and C540 jack. This causes arcing which can generate enough heat to melt the Latitude C640 and C540 dc jack and the power pin may become lose.
  
  

• Latitude C640 and C540 Backlight & inverters
  The laptop switches on but the screen remains dark. In some cases a faint image is visible on the screen. This problem can be caused by a faulty fluorescent light, inverter, video cable or a problem on the motherboard. Special equipment is required to determine the exact cause of the fault. Backlights use very high voltages and it is easy to cause more damage to the system if they are not correctly handled and installed. Our engineers can replace the backlight lamps in most TFT/LCD screens. We also have access to most backlight inverters and cables. We can also 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.
  
  

• Latitude C640 and C540 Keyboard
  Most keyboards are damaged by liquid spills and general wear. We can supply or install keyboards for most Dell laptops. We also repair keyboard connectors on the  system board.

• Latitude C640 and C540 Fan and Heatsink
  We can install replacement fans and heat sink parts for most laptops. 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 fan.
  
  

• Latitude C640 and C540 LCD Screen
  We can supply original and compatible replacements for most laptop screens. In some cases only refurbished screens are available. We don't charge extra for installing and testing screens. 
  
  

• Latitude C640 and C540 Hinges
  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.
  
  

• Plastics and case parts Latitude C640 and C540
  We can replace plastic case parts and trimmings on certain Dell models. Case plastics and trimmings can be very expensive due to the cost of stock control, picking, packaging and shipping. A small hinge cover, costing 5p to manufacture, can cost more than £40+VAT to the end user. Please try to understand the amount of effort and the processes that go into delivering these small parts to you. For most cosmetic scratches and minor damage, we would advise customers avoid repairs.
  
  

• Latitude C640 and C540 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. 
  
  

• Latitude C640 and C540 Speakers 
  In most cases these are damaged by liquid spills, dust or loud music - playing heavy metal music from bands like Motorhead will kill most laptop speakers, but can be great fun while they last.
  
  

• Latitude C640 and C540 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.
  
  

• Latitude C640 and C540 Power Adapters
  Some Dell systems use the center pin on the dc jack to identify the adapter being used. The systems will only work correctly with right adapter. We try to stock a wide range of power supplies to ensure that most systems are covered. 
  
  

• Latitude C640 and C540 Software and Drivers Repair
  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.
