Yes it did! :) Perfect! Thanks! I have been running the laptop now for an hour
and it is still working great.

Now if I run lspci -vv I get:
04:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT
[Radeon R7 M260/M265] (rev 81)
    DeviceName: AMD Radeon (TM) R7 M260
    Subsystem: Hewlett-Packard Company Topaz XT [Radeon R7 M260/M265]
    Physical Slot: 0-1
    Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B- DisINTx+
    Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort-
<MAbort- >SERR- <PERR- INTx-
    Latency: 0
    Interrupt: pin A routed to IRQ 33
    Region 0: Memory at e0000000 (64-bit, prefetchable) [size=256M]
    Region 2: Memory at f0000000 (64-bit, prefetchable) [size=2M]
    Region 4: I/O ports at d000 [size=256]
    Region 5: Memory at ff300000 (32-bit, non-prefetchable) [size=256K]
    Expansion ROM at ff340000 [disabled] [size=128K]
    Capabilities: <access denied>
    Kernel driver in use: amdgpu
    Kernel modules: amdgpu

Which basically means that the system can find it...so if I understand this
correctly (after googling) this command disables the driver power control and
this means that my discrete card is not automatically turned on? That suits me
fine since I don't use it anyway.
