Dynabook PAACA042 AC Adapter for Dynabook T / C series Review
Dynabook PAACA042 45W class AC adapter for the dynabook T6, T5 and C series (/W and /X).
PAACA042 is dynabook's official 45W class adapter with a round L-shaped 5.5mm plug, listed for the dynabook T6/W, T5/W, C7/W, C6/W, C5/W, T6/X and T5/X. dynabook says it has the same spec as the adapter bundled with those models. It is not listed for the T9 and T7, which ship with the 65W class PS0099NA1ACA, and we would not use it there. The 19V 2.37A output figure comes from third party sellers, not dynabook.
Fitment answer
OEM confirmed for the dynabook T6, T5 and C models below. dynabook's store states PAACA042 has the same spec as the adapter bundled with them.
Plug: round L-shaped, 5.5mm diameter, per dynabook. Output: 45W class. The 19V 2.37A figure comes from third party sellers only.
Which laptops this fits
dynabook T6/W (P1T6WPEG), T5/W (P1T5WPEG), C7/W (P1C7WPEL and P1C7WPEG), C6/W (P1C6WPEG), C5/W (P1C5WPES), T6/X (P1T6XPEG) and T5/X (P1T5XPEG).
Not listed for the T9 and T7. Those use the 65W class PS0099NA1ACA on the barrel port.
Connector and wattage checks
Wattage: this is a 45W class unit. The T9 and T7 share the 5.5mm round plug but ship with a 65W class adapter. A 45W unit on those can fail to charge under load. Do not use it there.
The plug's inner diameter is not published on the dynabook pages we read. Compare with your current adapter.
These models also take the USB-C PD adapter PAACA048, if you would rather carry one charger.
Genuine vs third party
PAACA042 is dynabook's official option, sold through the dynabook direct store with a 6 month warranty. dynabook names PAACA037 as the previous model.
dynabook does not publish whether its barrel adapters carry an ID signal, so a third party unit's behaviour is unknown. A replacement needs 19V, at least 2.37A, and the same plug. We would buy the genuine unit.
If this is not yours
Read the part number printed on the adapter you are replacing and the model code on your laptop's label. If neither appears on this page, this is not your part.

FAQs
Can I use a higher wattage adapter?
Yes, if the voltage and plug match exactly. The 65W class PS0099NA1ACA uses the same 5.5mm round plug, but dynabook does not publish its output voltage on the pages we read, so we cannot confirm the match.
Why does my dynabook say plugged in, not charging?
Check you are not running a T9 or T7 on this 45W adapter. A lower wattage adapter can power a laptop at idle and refuse to charge under load.
Can I charge these models over USB-C instead?
Yes. dynabook lists the USB-C PD adapter PAACA048 for every model on this page, and it charges through the PC's USB-C PD port.
