I am starting this thread to ask general raspberry pi questions, if you have any questions feel free to ask and we will try our hardest to answer in a timely manner with the best information we have on hand
Can i use my older 2.5amp 5volt power supply on the latest raspberry pi 4?
The answer is no the raspberry pi 4 is a little bit more power hungry and requires a minimum power supply specification of 5V DC via USB-C connector (minimum 3Amp).
It should also be noted that the with the introduction of the raspberry pi 4 the power comes in via a USB-C type connector.

We recommend this power supply:
My raspberry pi won’t boot up, i get a black screen what should i do?
The first thing to do is to check all your connections,:
-
With the power disconnected insure that the hdmi cable and mirco-sd card are inserted (HDMI-0, RPI 4)
-
apply power and the pi should boot
*If the pi doesn’t boot try and using another screen or monitor
*Alternatively try and reflash your mirco-sd card following this guide

Hi I was wondering can the rpi4 fit into the pi-top3 laptop shell?
Hi Nick,
I am sending you this stream as directed so that you can create a paper trail.
The Raspberry Pi I received 2 weeks ago (Order #2446), I have assembled as per instructions;
- fan works OK;
- red light comes on OK;
- but monitor shows nothing.
I know the monitor line is working because when I transpose another Pi onto it, it works fine.
There is no Green light next to the red light on the Pi board. This may be a good indication of the problem
I spoke with Kevin at Littlebird, and explained all this and he instructed me to send you this email to start up a paper trail so you can send me out a replacement Pi and include return bag for old Pi.
Is this correct?
Many thanks.
Could still actually be a monitor compatibility issue such as Raspberry Pi 4 Model B Showing Blank Screen .
What other monitors have you tried?
have tried all above. 5V 2.5amp power supply. installed updated OS - both from micro SD card and USB. all that comes up on the screen is a colour splash. can you please help?
hi, I’ve used updated sd and usb cards and on my third monitor, it reads underneath 4 red raspberries;
3.5603071 sd 0:0:0:0: [sda] No caching mode page found
3.5604951 sd 0:0:0:0: [sda] Assuming drive cache: write through
any suggestions?
Hey Mark,
Could you please attached a photo with how you connected the Raspberry Pi?
Cheers,
Marcus
hi Marcus 
I think I can only add one photo per post so I will post twice … here goes …
I hope this helps.
Thanks for this Mark,
Would you be so kind as to show me the underside of the Pi (where the SD card is located)?
Cheers,
Marcus
Thanks Marcus here is the underside with a 32 Gb micro sd card with the latest Raspian OS downloaded and unzipped in it. every time I now turn this Pi on, I get a message “waiting for sd card (settings partition)” with a sliding blue meter going left to right to left etc. Forever.
underneath there is a red raspberry with another option "For recover mode followed by the SHIFT key. whether I press the SHIFT key or not, the above sliding meter keeps sliding and nothing happening. Does all this make sense to you? I hope you’ve seen this before.
I’ve tried installing two other Respian downloads, from another 2 sd micro cards and even via the accompanying gold coloured little USB drive, with no success.
I really think it might be easier if I tell you exactly what is happening live - just give me a call on 0417-375-677. Otherwise, this could just be a faulty unit? would you like me to return it?
I have had NO PROBLEM with a previous Pi sent just 2 weeks before.
Best wishes, Mark
