I have just taken delivery of a used Lenovo T520. Partial BIOS data

BIOS Information
Vendor: LENOVO
Version: 8AET51WW (1.31 )
Release Date: 08/08/2011
It has a RealTek WiFi adapter:
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE
802.11b/g/n WiFi Adapter (rev 01)
I had a devil of a time getting it to fly; it didn't even show up in
lspci.
Finally, out of desperation, I booted Windows. I was able to examine
the device using the Control Panel, including the PCI bus address. I was
also able to hook up to my home network, and extract the MAC address.
I then shut the machine down completely. When I booted into Linux, the
device was there, and the network worked immediately.
So I conjecture something had had the device turned off, to the point
that it did not show up on the PCI bus. I also conjecture that Windows
had found it and enumerated it it for its own use, and left it turned
on.
So my question is, is there a Linux tool for turning on PCI devices in
such a situation? In case something makes this device disappear again?
