PineBook Pro revision 2.2: Wishlist for the hardware issue fixes

[dsimic]

@dsimic - actually you're doing great job with your list here. Even if p64 does not want to recognize it. Everyone should be aware of what she/he is buying. So there are no disappointments later.

Thank you very much, but it would be way better to have the Pine64 team recognize the issues, or even just become involved in the discussions.  There's no pressure, but they should be standing behind their products, which includes the PineBook Pro.

1. Underpowered USB ports (even 2.5" external hard drive does not work - eg. for backup purposes).
2. Underpowered PCIe - not every nvme drive can be used. Only those that are not DRAM cached.

Those two issues stem from the overall lack of input power for the PineBook Pro.  Actually, I asked the Pine64 team to send me one PineBook Pro for the purpose of trying out a few experimental hardware modifications that should allow higher power draw from the laptop's USB Type-C power input.  Unfortunately, I've got not response from the Pine64 team so far.

4. Coil whine in most of Pinebook Pros.

I would also add some weird crackling/popping noises coming out of the speakers while no music playback is active.  I've been unable to correlate those sounds to anything else happening on the laptop, except for the moment of powering off the laptop, which always produces a crackle/pop.

After one year of trying to use PBP as a daily I came to the conclusion that it is impossible in my case. It's a great machine to learn and get to know ARM ecosystem but it's only a toy. Nothing more. Mainly because it's faulty by design.

For example, the battery charging IC is so finicky that it has a mind of its own when it comes to stopping the battery charging.  Quite frankly, that's simply unacceptable.

One of the best think is that it is possible to charge from USB 5V 3A. Please keep this possibility!

Could you, please, elaborate that a bit further?
