This part, C6 is a “just in case” component which is good design practice to include, but as it turns out most power supplies still work OK without this part installed. Out of the box, R-Pi graphics don’t necessarily fill the whole screen. One suggested remedy to this, which has some positive feedback, is to adjust the USB bus speed. A logic analyser or a digital waveform viewer is a very useful tool to diagnose problems with the gpios. If the PI resets at that moment, it is an indication that the power supply isn’t able to deliver the full current your PI requires, but dips its output voltage below a minimum when loaded with the full current the PI needs. The wiki has a list of working SD cards.

Many wireless keyboards are known to have “sticky keys” on the R-Pi.

If you have the Rasbian Wheezy image recommended then try. The Spanish article has numerous color temperature images of RasPi in various operational modes, with the highest LAN case temperature measured as With current firmware, a coloured splash screen actually its just four pixels “blown up” by the GPU to full screen is displayed after GPU firmware start.

Some USB devices require logitech wireless mouse m210 lot of power: For a quicker way to force wheezy into booting in safe mode, logitech wireless mouse m210 doesn’t need editing config. Some wireless keyboards, for example the Microsoft Wigeless Keyboard are reported to fail [14] even though the current drawn by the wireless adaptor is within the R-Pi USB spec limit of mA.

Updating the firmware can be done kogitech rpi-update. See a complete list and user feedback here: Two test points labelled TP1 and TP2 are provided on the circuit board logitech wireless mouse m210 facilitate voltage measurements. If you think muose have a problem with your power logitfch, it is a good idea to check the actual voltage on the Raspberry Pi circuit board.
