HP LAPTOP REPAIR FAQ:

HP Pavilion Dv7-4020sa Dv7-3020sa 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 HP motherboards. We replace resistors, capacitors, transistors and also work on the major chips, such as the video chip, within your system. Our engineers have many years of experience and know how to fix most motherboard faults.

HP Pavilion Dv7-4020sa Dv7-3020sa VGA Video Graphics faults
The computer 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.

HP Pavilion Dv7-4020sa Dv7-3020sa 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 Pavilion Dv7-4020sa Dv7-3020sa jack. This causes arcing which can generate enough heat to melt the Pavilion Dv7-4020sa Dv7-3020sa dc jack and the power pin may become lose. It is best to get the HP 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.

HP Pavilion Dv7-4020sa Dv7-3020sa LCD Backlight & inverters
The laptop switches on but the screen remains dark. In some cases a faint image is visible on the Pavilion Dv7-4020sa Dv7-3020sa screen. This problem can be caused by a faulty Pavilion Dv7-4020sa Dv7-3020sa 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 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.

I would like to convey my appreciation for the work you did on my daughter's laptop - you have saved many years of vital data... Got the wireless card working on my HP... The manufacturer kept me waiting for months to replace my Compaq keyboard - LaptopRepair1.co.uk got it and installed it in 24 hrs - EXCELLENT SERVICE... One morning my Advent screen started getting strange dots all over. LaptopRepair1.co.uk diagnosed it over the phone as a Graphics chip faults. I sent them the laptop and they fixed it in a week - thanks.... I rang over 20 companies to get a keyboard for my HP laptop, only LaptopRepair1.co.uk had the right part. HP wanted to send my laptop top to Europe and format my hard drive

All your programs and data are stored on the Pavilion DV7-4020sa DV7-3020SA hard disk in your laptop. Important HP data should be backed up on a regular basis. A few minutes copying your work to a CDRW can save hours of data re-entry. It might not be possible to repeat certain types of design and artistic work. Smart Pavilion DV7-4020sa DV7-3020SA hard drives will sometimes warn of imminent failure, other warning signals include a change in drive noise and intermittent Dell read errors. Any warning sign should be taken very seriously and the drive backed up ASAP, if possible. External USB or Firewire drives are an excellent means of Pavilion DV7-4020sa DV7-3020SA backing up important data. They are almost as fast as the internal data and can be used to transfer your data to a new hard drive if your current drive fails. Older laptops may have a restriction on the size of drive that can be installed. To enter the bios on most Fujitsu laptops you need to press F1,F2 or the Del key quickly after switching on the machine. High voltages are required to run the backlight in the HP laptop. This is provided by the backlight inverter.
