UV curing adhesives use ultraviolet (UV) light or other radiation sources to initiate curing and form a permanent bond without heating. Ultraviolet (UV) or visible light cures or polymerizes a combination of monomers and oligomers in a UV adhesive. UV curable adhesives consist of monomers, oligomers, photoinitiators, additives, and sometimes UV transparent fillers. The ability of UV adhesives to rapidly cure without heat provides energy savings and productivity gains. Some UV curing adhesives contain additional modifiers such as fillers, pigments, or chopped fiber reinforcements. Use temperature - The range of temperatures to which products can be exposed without the degradation of structural or other required end-use properties. Dielectric strength - The maximum voltage field that UV curing adhesives can withstand before electrical breakdown occurs.
Dielectric constant - The relative permittivity of a material compared to a vacuum or free space. 9985979 - This specification covers a family of single component, solvent free, fast setting, acrylic adhesives that cure when exposed to light, either in the visible or ultraviolet range.
MIL-PRF-24793 - This specification covers the requirements of a UV curable liquid adhesive for bonding optical fibers to glass fiber optic splice, connector, and terminus ferrules. Conformal coatings encapsulate circuit boards and their electronic components in order to prevent the ingress of moisture, fungus, dust and other environmental contaminants.
Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. Silicone adhesives and sealants have a high degree of flexibility and a very high temperature resistance (up to 600° F), but lack the strength of other epoxy or acrylic resins.
It is formulated for use when participating in water sports to protect against UVA and UVB. Processor is an Intel i7-4712HQ which is now a BGA mounted type and what is good about this refresh model it has both VT-x and VT-d enabled, not to mention it has a low TDP of just 37W, which I prefer in this type of single cooling solution notebook, as it keep the amount of heat under control.
Touchpad is very much improved and has what I believe to be a glass coating on it, which make it very usable. HP has also removed 2 speakers from the front underside of the leading edge of the laptop and one of the subwoofers. Personally I have found the speakers took a little more volume to sound loud, but once around 70% it can easily fill the room, and the subs add to the fullness of the sound.
Even though there are non-changes, there as a couple of things that have been slightly revised cosmetically on the machine, the palm rest features an extended grill holes along the top of the palm rest. My particular model I am reviewing is the one and only single pre-build model that I can get in my particular country which is a TouchSmart model. HWINFO shows various details, which are pretty much obvious if you know what you are looking for such as TDP, memory timing sets, cache size, hard drive cache, special features of the CPU, etc. I have a NVidia Shield Portable, therefore with the GPU being of GTX class, then this is compatible with NVidia steaming. Make not mistake this GPU is very powerful, it will easily cut through most games on high and sometimes even ultra. Intel Dual Band Wireless-AC 3160 from about 10 metres away and through several wooden walls, I am getting a decent stable connection to my AC router, often seeing the connection speed as 433 Mbps. Keyboard is essentially the same as last years 15-J, with the exception of the 15-Q colour scheme being changed silver and the backlight is now very light blue, although to me it look more white than anything. I personally don't like it, but I brought this knowing that the flex is still there, but was not prepared to how annoying it was going to be, I tried not to care that much this time around, but it is really a poor design. Although you must be prepared for the keyboard to be raised up significantly with a lot of movement around the 2345QWERTYASDFGHZXCVB area which is a lot of keys, and there is a bunch further to the right hand side between the number pad and Enter key area. During the day time the keys are readable, but make sure you don't turn on the backlight (not that you would want too, otherwise the letters on the key cannot be seen.
As about you can see the size of the touchpad which is very wide and its surface is so much better. In the market area where HP sells the these particular notebooks, every year they stick in the 62Wh battery packs and reserve the low rated 47Wh pack for the lower cost machines. Power brick is 120W slim type, pretty much the same as last year with the same barrel connector. Display panel has poor viewing angles, and darker colours in the top corners pretty much invert if you look at the screen directly, which is not good, there is also a bit of grainy effect too. Not going to post a photo here, but you will be able to see from the photo near the top of the post what it look like. During gaming (which I haven't really had the time to go into just as of yet), the fan will ramp up, but much less than last years i7-4702MQ and 750M combination.
The MacBook that I already own I usually use on the couch, but that is not a windows machine (I don't like boot camp with 650M as it never switches off), therefore for the HP is a good one for cruising on couch with the touchscreen at hand. The first time around (with the 15-J), there was no FHD option on last year 15-J that I no longer own, in which I hated it HD resolution, it is good now to have FHD. The only disappointment I really have with this is that there was no other models available (just a single pre-built), thus having to shell out top dollar for top spec model, and with that being a touchscreen.
The main reason I can see for this notebook is primarily the Maxwell GPU, why wait when can have right now.
I will be tweaking the review as I settle into the refreshed 15-Q, therefore will continue to be a work in progress, add and change things as necessary in due time.
This #2 post I will add things like tweaks, benchmarks, overclocking the CPU & GPU, once I have finished near fully finished writing the above post. Just to start off (will organise this better as I go along) will post a couple of screenshot of the 850M overclocked. I found that the 850M will easily overclock to its maximum that NVidia will allow which is +135MHz on the core.
The memory on the other hand overclocked as expected, it is DDR3 and I was not expecting any miracles, and general went to where I figured it would reach.


Under load you can see in this following screenshot, where exactly the boost clock is getting to.
Processor overclocking of the i7-4712HQ is easily obtainable by simply download Intel Extreme Tuning Utility, then installing, reboot and tune.
UEFI is not that extensive, but we all know that is the way with HP consumer line notebooks.
May be that you can find that there is the power supply, but there no easy mode to verify if all the other signals are ok. There are about 25 pins on each side of where the solder points are on the board, they are extremely close together. Also take into account where the wires have been run over this area by HP, they are tacked down to this area. This is pretty much what I have been trying to point out, there just may not be anything active to connect up. I have wondered that maybe I got a motherboard where the mSATA connector was no soldered on by mistake during manufacturing, but felt that would have been highly unlikely. I paid an excessive amount of money for the one and only pre-built mode in my country, and with it being the top and only model it should of came with at least a very good TN panel, or and IPS panel. The display panel really is the major let down, and being touch screen there is no way to be replaced. I still recommend this to USA buyers if they don't care about keyboard flex, and it they are happy to replace their panel with something decent. Regardless, it's a great deal for the parts you get (FHD display, i7 quad, gtx 850m) in the US store at least.
That's true, at that price you could add an IPS display, and a 1tb ssd, and still be cheaper than other brands. UV adhesives are also known as radiation curing or radcure adhesives because UV is a radiant energy sources. The light or radiation sources used in the UV or visible light curing process include medium pressure mercury lamps, pulsed xenon lamps, LEDs or lasers. The UV photoinitiator component generates free radicals or actions when exposed to UV light, which initiate crosslinking between the unsaturation sites in the monomers or oligomers. Energy savings occurs because capital expense and production floor space required for the costly ovens required for thermally curing adhesives is eliminated. As a result, no water or solvents are released to the environment, which is better for the environment (no emissions) and safety (no flammable fumes) as well as water or solvent sensitive parts. Others contain solvent-based adhesive resins which use a volatile organic compound (VOC) to thin or alter viscosity. Others, which are more common, begin tacking when contacted by UV, but still require a given length of time to fully set. They require clean surfaces and are valued for their toughness and resistance to chemical and environmental damage.

I hated the last year 15-J model touchpad which is hideous to use, often grabbing and gripping the fingertip like glue. HP has decided to remove the connector, and even if added, then I would suspect the supporting circuitry and UEFI support has been removed.
Such as the display panel types that are being reused, but that is understandable somewhat (even though I am not exactly thrilled with the quality) as this is something that uses the same part numbers.
I have been using over the course of a day, and the worse thing about it is the pitiful viewing angles, this thing is ridiculous.
The underside plastic is slightly different with the removal of the speakers, thus closed off or solid plastic. That does not matter much, as this is generally still the same 15t-q000 model, with a few pre-defined specs.
You could actually install a mSATA cache but without the actual connector it isn't going to do anything.
This also means if you were to pick up the newly release NVidia Shield tablet, then you could steam to that too using the Envy GTX class GPU. In the screenshot is running the new Wolfenstein game at custom, set to high with everything else set to tap into the texture as much as possible, as you can see is using about 2.3GB of VRAM. The keys are the typical mushy and flex ones, so no improvement here, although most people will not be so fussy and care. The keyboard is good enough to type reasonably fast on, which I am writing this on right now, so despite the flex it is useable buy definitely annoying. On the other hand at night, the keyboard looks really good with plenty of light, key are easily readable. I am not totally sure but it certainly feels like a glass finish with finger slipping freely over the surface. Personally one of the main reason to have a notebook is to have decent battery life, in general the 62Wh battery performs good and last a decent amount of time.
However I do have the touchscreen version, not sure it then overlay affects the panel somewhat. I have been following this even before I actually knew anything about it, and posting a substantial amount of information in the main 15-qXXX thread, basically after all of that, there was no way I could not get it.
My alienware 14 simply is not that pleasant to use on the couch is a bit heavy even though is 14 inch and pretty dam fat, for casual use anyway. However I would not recommend using directly on lap if you are going to be power the machine during gaming or extensive tasks.
Being a touchscreen means there is no chance of changing out my poor TN embedded under glass panel for an IPS panel, but if I look on the bright side I do like touchscreen and laptops experience. When HP updates the GPU later on, once Intel Broadwell is out, no doubt it will be just a rebrand part.


This results in a base clock of 1037MHz, with a boost clock of an incredible 1219MHz, which is really good for a laptop form factor. I was able to overclock it +255MHz, but that resulted in the odd texture flash during gaming. Just move all the processor multipliers up to their max including the cache ratio, click apply and your done.
Although they are not a permanent fixture, there maybe no wriggle room to move these to the side, if you could get a mSATA connector in here. From the UEFI screenshot in the post #2, there is not anywhere to configure RAID, as far as I know without RAID enabled, then cannot use RST to create a cache drive. If so then I think there is only about 5-6 pins than will need to be connected from seeing someone else that had wired up a mSATA drive to bare connectors on a notebook motherboard. There is a chance the connector may return as my notebook is a very early model, and has been sitting at the brick and mortar store since end of June.
I had the chance to see two different 15-Q and both has way more flex in the keys, especially to the left of the keyboard. With the HP 15-Q panel being so bad, this one is particular bad, much worse than an average Acer v5-571pg (1366 x 768) touchscreen, really at the price paid it wasn't worth keeping.
Thermally cured adhesives can take hours to cure compared to UV adhesive, which can cure in seconds to minutes. There are 640 shaders and 2MB on die cache for the GPU, even though we are still limited to DDR3 memory in the HP that is not impacting performance as much as one would have expected due to the new architecture. The 15-Q new touchpad is a pleasure to use; no longer do I feel frustrated using an Envy 15 touchpad for the first time in history. Also there are several other parts that are just the same, after all the unit is a refresh model, not a brand new model. The viewing angle is so bad that when looking straight on the top corners invert (colour flip), this is really unacceptable, everyone should be able to look at their display straight on without any inversion, I tried to ignore it but it is way to pronounced. On the edge of the motherboard next to this particular area there is soldering joints for a connector, no idea if these are still physically active or not. This is enough for what it is (considering I am not right next the router), I am restoring games from my steam library backup at a considerable rate over wireless, e.g.
Here is a photo of the keyboard looking down in a slightly darken room by closing the blinds. If it is not glass, then whatever it is, maybe special metal, it just works better than any of the previous touchpads that HP have put on their laptops.
I have been writing this thread and editing photos over the last 3 hours over a RDP session connection to my Alienware M17xR3 via the HP 15-Q wireless connection, I still have a good 30% battery remaining from the first full charge. Seems ok brightness, could be better, the colours are a little washed out, but in all generally better than HD panel The touch screen is good and functions well. If there is a fair bit of load for sometime, then the fan will ramp up, at the same time very acceptable. Not exactly anywhere near a SSD and no way it could ever be, but the transfer speed is pretty good with large files.
This will keep me happy until I can get my hand on Broadwell quad and maybe a die shrink of Maxwell, although that is a long way from today. The good news for those of you that can get it without a touchscreen, HP are using the exact same part number for the display cable, which means it will be a straight swap no matter if you have a HD or FHD version originally. Most importantly to me is the minimum frame rate which moved from stock clocks 29 FPS to an overclocked frame rate of 36 FPS. Do you think they'll continue to have Beats in the near future (as Apple just bought out Beats)?
I don't know what the long term deal is with Apple, although HP could have a contract with beats that has not expired yet. On second thoughts, HP would of not routed the cables at the same time tacking them down over the mSATA connector if it weren't meant to be there. Basically the entire left hand side would move up and down with a single and very light key press. HP have run some cables over this area which are glued with a rubber stopper and a piece of tape, so pretty much they are not intending to use this anyway.
While I am not expect great frame rates if using over 2GB VRAM, the fact of the matter is that is can. HP calls this touchpad Control Zone, there is a left and right side which are slightly coloured to mark special swipes, seems to work ok, that part of the surface has a different texture on it, it tend to grip a little bit, but not much of a problem as the middle of the touchpad is pretty vast.
Great thing with a 37 TDP processor, it will stick to those limits thus fan noise is not much of a problem, which is not the same that can be said about a 47W processor as these get loud with the fan very quickly from my own experience. Overall I might be able to put up with this drive until I can afford a SSD and that is will only be ~480GB, but I really want the space of the mechanical 1.5TB to install games on the drive. However I need to run longer gaming sessions, but considering that I have only just got this, I haven't had time yet to get into specifics. On the boot page there is no RAID configuration area, such as the 15-J from memory actually had. I would figure that HP have written this port out of the UEFI, and I would think that any supporting circuitry may have been removed? Memory is clocked a little low, but should be easily be able to take at least 100MHz overclock.
What I am trying to determine if there is anyway that the mSATA slot is active for using Intel RST, which from my understanding needs to be enabled for it to work? The four load cell sensors are attached to the glass with UV glue allowing the spun aluminum disks to show through.
