Frequently Asked Questions:

NOTE: Some of this information is several months old and now may be incorrect. An update is in progress; please check back in a few days.

Is the DreamColor display the original DreamColor or the DreamColor 2?
The press release confirms that the 8740w will be offered with a new DreamColor display. HP Fansite referred to the display as DreamColor 2. Also, orders with DreamColor contained the following line item: VG322AV LCD 17.0 WUXGA+WVA DC2 f/CAM 8740w.

When will the DreamColor 2 display be available?
HP initially offered DreamColor 2 in late March, but later cancelled the orders. HP provided no public explanation. In late June, HP once again started taking orders for systems with DreamColor 2. Initial delivery is estimated for mid-July.

Is the DreamColor 2 display a 10-bit IPS panel?
Yes, according to HP Fansite. The press release confirms 10-bit color, but not the panel technology. A post in this thread claims an email from HP confirming the technology as IPS. (credit: NotebookGrail)

Will the DreamColor 2 be available with all of the offered GPUs?
Yes. There was an early rumor, based on a comment at HP Fansite, that the DC2 and ATI M7820 were incompatible, and thus the DC2 would only be offered with the nVidia 2800M and 3800M. That appears to be false. This YouTube video shows the 8740w being demonstrated with M7820 and DC2 by an HP employee at a trade show.

What are the differences between the ATI FirePro M7820, nVidia Quadro FX 2800M, and nVidia Quadro FX 3800M?
Articles at HP Fansite and Engadget indicate that the M7820 is based on the ATI Mobility Radeon HD 5870, a top-tier card. The M7820 differs from the 2800M/3800M in that it likely will support DirectX 11 and ATI's Eyefinity multi-monitor technology. The GPUs will differ further in their certifications for various professional applications.

How many external screens and what max resolution does the M7820 support (via ATI Eyefinity)?
This YouTube video and this Tom's Hardware article show the 8740w driving three external monitors in addition to the built-in panel. A post in this thread claims support for up to four external monitors.

How many memory slots does the 8740w have?
Dual-core models come with two memory slots, quad-core with four memory slots. (credit: Thecla)

What make/model is the 256GB SSD offered by HP? Does it support TRIM?
Probably Samsung. Don't count on TRIM support until HP finishes testing the firmware.

Does the 8740w have a backlit keyboard?
The 8740w may be configured with a backlit keyboard.

What kind of discounts or coupon codes are there?
Some report discounts up to 28% by calling particular HP reps. HP also regularly offers a discount on its web site.

Can anyone get VT-x working with ubuntu in VirtualBox? I can't, but I know VT-x is a feature of the i7-840qm

Reply to this post from the old thread:

That's what I was waiting for. Yes, that's most likely a HDD problem. It may be a bad sector/s but checkdisk would have found it, - so, looks like a file table shift. Such things can be fixed easily with a format.
I'm not sure if it's worth trying some expensive disk doctor tools...

I agree, but if you are not able to get rid those bad sectors once you've formatted the disk (select full format!), I recommend knight427 consider the awesome HDD Regenerator tool. You can run it in order to do an in-depth scan and, in trial mode, you'll be able to fix up to 1 bad sector (if any). Most times, bad sectors are produced due to improper sector magnetization. If this is the root cause, HDD Regenerator will fix them without problems.

@Aikimox, did you happen to copy the contents from the first 3 posts of the old thread. Looks like SAM has deleted it. Let me know, if you run out of luck, i have a local copy

[NotebookGrail]

To DC2 owners. Let me know if you see this problem. I have reported it before, haven't got that many responses.

Configure DC2 to your liked color space and luminance, etc. When you boot your computer wait until the HP MDA loads and icon appears in tray. Now open HP MDA, you should see the brightness increase/decrease based on your set luminance.

Now again reboot the notebook with the power not plugged in. Wait until HP MDA load and appear in tray. Now, plug the power back in. You should obviously see the brightness increase/decrease to the setting that HP MDA was configured to (without even opening the app - not just to default windows brightness, but to the one set in HP MDA).

I find it really annoying that the HP MDA doesn't properly load even when set to load during start up.

[m8o]

Yep, bios F.05 broke the startup of the MDA. It used to work right, remembering the previously loaded gamut and intensity, on battery and on power-plug, in F.03.

I noticed a new annoyance today. I was working in Lightroom, so I set the HP Power Assist profile to High Performance. That translates to setting the OS to High Performance. Well, my High Performance profile had max brightness set to 90% for some reason. Then, because the OS's brightness intensity was set outside of the MDA, the MDA profile was altered to get "User" prefixing the name, and the old "red/yellow tint" effect kicked in. ...all within the course of a few seconds. Resetting the gamut profile to the default set everything back (after fixing the OS's Max Perf profile to have a display intensity of 100%), but still, annoying.

Check Disk took forever to run this time, and it found lots of stuff to correct I guess. I'm back up and running. Thanks to everyone for their help.

[Aikimox]

Hmm, I don't see any problem (F.05). The brightness changes slightly around the value I preset in the MDA, and it's totally in sync with the ambient light. At least, that's how it looks to me. Never had the tints, unless using the Fn+F10/9 keys or forcing the brightness change through the OS power profiles.

Check Disk took forever to run this time, and it found lots of stuff to correct I guess. I'm back up and running. Thanks to everyone for their help.

The problem will most likely return soonish. This is what I call the "shift". Could be due statics buildup and might result in a drive failure. Better be ready to upgrade to a SSD
