Portege M400 R400
LCD Backlight & inverters The laptop switches on but the screen
remains dark. In some cases a faint image is visible on the Portege M400 R400
screen. This problem can be caused by a faulty Portege M400 R400 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. 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 operate on a customer's LCD/TFT unit.

Portege M400 R400 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.
Most CPU failures are cause by BGA problems. Overclocking a Portege M400 R400 CPU in a laptop is not recommended as the
cooling systems are designed to dissipate heat at normal speed.

Secondhand
or Used TOSHIBA Portege M400 R400
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 TOSHIBA Portege M400 R400
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.
