I recently purchased a 6735S and am interested in the possibility of upgrading the graphics capabilities of the machine.
The motherboard chipset of this model is the ATI 780G ( http://www.amd.com/us-en/0,,3715_15532_15533,00.ht
A feature of this chipset, is that it supports 'ATI Hybrid Graphics', allowing the integrated 3200 core to work in conjunction with an additional dedicated 3400 card.
This capability is also described here :- http://www.notebookcheck.net/ATI-Radeon-HD-3200.95
I have a couple of queries relating to this :-
1) Does this laptop provide sufficient internal space & necessary connections to add a Radeon 3400 series card?
2) Is the expansion interface ATI's AXIOM or the more generic MXM?
3) Where would I go about obtained such a card?
4) Will installing such a card invalidate my manufacturers 1 year warranty? (from my own research, this appears to be almost certainly yes)
Solved! Go to Solution.

hmm, I don't think that's what the ATI 'hybrid graphics' is relating to.
I've found this :-
Which links to this :-
The interesting section is on page 2 of the pdf - "Notebook Systems with ATI Hybrid Graphics"
This diagram indicates that the upgrade mechanism is via insertion of an ATI Mobility Radeon HD 3470/3450 daughter board.
This then works in conjunction with the motherboard's AMD 780 chipset to give an "ATI Mobility Radeon HD 3470/3450 Hybrid X2".
So, while this does appear to support my initial understanding, it doesn't get me any closer to answering my initial questions!
Also, from the microscopic small print on that brochure, it appears hybrid graphics is only supported in the Vista drivers, not Windows XP
(though I suppose I could get around that by dual-booting into Vista when intending to play games.)
Also found this on the hp website :-

I understand what you're saying...however you would need an adaptor that hooks through the expresscard/54 slot on the side of the computer to do what they are claiming.
The only one I know of is the one I showed you, which is still under development.

Here is a link to the MXM bible. Your laptop is not an MXM and as far as I know it does not have upgradeable graphics:
Here is your Service Manual which shows the innards in their entirety:
Laptops generally do not implement all the features of the corresponding desktop chipset, and only a paltry handful of laptops have upgradeable graphics. You generally have to buy a laptop with the graphics you want to have for the life of the laptop, not with the idea of adding something better after you get it.
The feature you are talking about is Power Xpress and it allows you to switch from onboard graphics to a dedicated video card on the fly without a reboot, but it works only in Vista, as you noted. It is one of the features of the Centrino 2 platform, or at least the option to implement it is. Fujitsu has released laptops with this feature (very expensive) and others are poised to do so but I don't believe HP has issued one yet.
nVidia also has a similar option and it has been released on at least one Sony Vaio I believe.
These are top of the line laptops and the dual video option has to be built in at the factory; it is not an add-on feature.
