Is Thunderbolt retroactively applicable to existing G55 models via BIOS or driver update?
Current G55 models are NOT upgradable to Thunderbolt via BIOS or driver update. They contain no Thunderbolt hardware inside.
What is that port used for on non-Thunderbolt enabled models?
The port is used as a DisplayPort video output. You can hook up DisplayPort monitors or use an adapter for other connections. DP is great for super-high res monitors as it can output 2560x1440/1600 resolution whereas HDMI cannot.
What is that port icon then? It looks like Thunderbolt
It does not confirmation that your G55 contains Thunderbolt inside, as all G55 chassis are identical.
The Intel Thunderbolt icon is a circle+bolt, however the G55 icon is a square+bolt to indicate the duality of DisplayPort (square) and Thunderbolt (where available). This icon decision was made early and couldn't be replaced - we're very sorry if this causes confusion.
When will Thunderbolt models be avilable?
Thunderbolt enabled G55s will be available 'from July', but it won't be in all regions simultaneously: local distribution can take time and retailers get to choose when/if they stock them.
Will all G55s in July have Thunderbolt?
No. Not every G55 will have it. G55s non-TB will exist alongside G55s with-TB. You MUST check the retailer specs page first.
How will I know the model is Thunderbolt enabled?
Retailers will list 'Thunderbolt' or 'Intel Thunderbolt' under the specs on their G55 product pages: you MUST check before you buy as it cannot be enabled retroactively.
Retailer X shows a G75 with Thunderbolt available!
This is falsely listed. Please give me a link and we will get it corrected.
G75s with Thunderbolt will be available later this year and we will announce availability when they are ready.
Thank you all!
