7520 no Serial Port COM
I recently purchased Precision 7520. Upgraded bios to latest (1.26) and installed Win7 and as well W10 on M2 device.
On both there is no present Serial Port COM(X) in device manager. I don't see conflicts (by type) and Address and IRQ 3 or 4 are not used.
I tried disabled / enable Serial in Bios but nothing happened.
Any idea?

There is no RS232C Serial port listed for this model.
If you need a serial port you will need to purchase a USB to RS232C serial adapter. However, I find these to be inconsistent, so buy where there is a liberal return policy if it doesn't work.

Via dock station there is RS232 and in bios there is such setting (and also Parallel LPT but there is no problem with it)
THe same way I use with HP 8570W

I have a USB/RS232C adapter. The adapter shows up in the Device Manager but not the BIOS.
A docking station RS232C port would show up the same way, in the Device Manager.
