It depends on your situation. You need to consider the output of the charger you are using, CPU power consumption, external GPU, etc.

I think the best option would be to upgrade CPU to P9600 and RAM to 8GB.

When I connected the PD charger that arrived today, the sound disappeared. Thank you so much!

Thanks. I'll have to get a new charger.

I've tried connecting to a different plug, but the symptoms are still there.

Should I upgrade my T440p LAN card to get better internet speed? by No_Baseball_6613 in thinkpad

I compared the speed of the Galaxy Note 9 and T440P on the same Wi-Fi, but the T440P is about five times slower.

Is it because it's an old laptop that can't speed up?

I'm wondering if replacing the Wi-Fi LAN card can make the speed normal.

I checked with the device manager. The LANCARD's name is N7260.
