| Those are very good prices, it's 3700EUR in Austria

| just not the ideal model I had in mind. The hardware is great

| That particular laptop also seems very heavy.

| desktops -- though an Alienware 15 I had died earlier
| than it should have because the battery swelled up and
| damaged the circuit board. The machine still sorta but
| made a chime every 30 seconds or so because it thought
| USB devices were being plugged or unplugged or something.

| The last laptop I bought from HP was a ZBook 15 in 2014.
| I'm still using it. It's rock solid.

| on into Ubuntu (from HP!) of Windows... It does not charge or
| use the power at all. Even with 140W 3rd party chargers from
| Anker, Ugreen, Insignia, etc.
|
| Super limits its usability.

| For me the firmware 0x01030b00 solved most of the problem.
| It now runs well on my previous laptop 65W HP charger,
| which is much lighter than the literal brick the G1a came
| with. It still does not work on an Anker 140W power bank I
| have.
|
| However this firmware was only available on HP's website
| for a few days. It has now been retracted, but it works
| well for me so YMMV.
|
| My last remaining hurdle is getting color correction
| working for the DCI-P3 OLED screen. Maybe it's a
| Gnome/Wayland thing but I cannot get full display
| correction to work so colors are ultra saturated.
|
| Edit: the fan curve is also bad, it makes fans spin up/down
| continuously under certain conditions. Not a deal breaker
| but quite annoying when it happens.
| green7ea wrote:

| much better.

| The AMD Framework laptops have the same issues, I've heard

| C/4/PD is just broken (or at least extremely difficult to
| write firmware for)

| I have one as well and haven't had this problem. I've been

| 6.17.8-arch1-1, it could also be fixed in newer kernels.
| When I play demanding games, it pulls quite a few watts and
| all the chargers are keeping up.
|
| It might be your device that is unlucky, maybe contacting
| support might help.
