Touchpad buttons

I recently upgraded my laptop from Vista to 7 Pro 64 bit.
I've installed some drivers, and have most hardware working correctly, including the WiFi and volume touch buttons. However, the Information button (left of WiFi) and the (presentation?) button right of the WiFi button, and left of the Caps Lock light. I have been unable to find any drivers for these.
What can I do? It looks like all the drivers I should need are here: http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=3355661&swLangOid=8&swEnvOid=4059
but I'm not finding anything that helps, although I did see a link for "HP Quick Launch Buttons" (sp46731.exe). When I try running it, I'm told I already have a newer version of that software.
What can I do?
Thanks!

So you have separate left and right buttons? Not intergrated into the touchpad? I would investigate the touchpad settings to see if somehow the button assignments have been changed. Also try uninstalling the touchpad driver and re install it. Make sure to do a re boot before attempting to re install the driver. If this does not work, you will need to contact HP technical support and have them advise if you have a hardware issue. Sounds like the ribbon cable for the touchpad might not be connected properly.

How to deal with those pesky touchpad buttons

The Pavilion series laptops are really well made in a lot of respects. I have owned my DV5t for almost 4 years now and I've been quite happy with it (except for rather anemic battery life). There is one thing that became a nasty problem for me, that being the left touchpad button. It is the most commonly used touchpad button and unfortunately these buttons were not well designed. They can easily break after a certain number of hits, whereby there's no longer any spring to it. Pressing the button ends up getting double-taps like mad. Also, the silver coating on them tends to wear away, looking rather unsightly over time. Once you start seeing the black plastic beneath, it won't be long before the button breaks. It's really a shame, because these tactile feel buttons work well--they just don't last. The newer HP laptops have those "lite touch" buttons which I do not like. The tactile feel is so much better. Unfortunately, it seems like most laptop makers are going with those solid state buttons to avoid another component that might go wrong. It's a shame, because with just a little more effort they could have been designed to last a very long time.
As of this writing, I have now gone through TWO of these touchpads. How did I manage to get another two chances? Well, they can be replaced but unfortunately they require you to disassemble more than half of the laptop. You see, the touchpad is integrated into the palm bezel, and the palm bezel is a piece of plastic coated metal that runs all the way to the back of the laptop. To get at it requires about an hour of taking the laptop apart. It's not for the faint of heart either. However, there is a service manual available that shows you what to do and I was able to follow it... thrice. Yes, the first button wore out after just under 2 years. The second one held up about as long. I use the touchpad buttons frequently, so... well, needless to say, now that I've got the 3rd bezel in place, I am going to rely mostly on an external mouse. And when I have to use the touchpad, I am going to use it very carefully, not exerting too much pressure (note that you can also tap the touchpad itself for a single click, something good to get into the habit of doing). Additionally, I'm going to put a sheet of protector plastic on the left mouse button to help avoid wearing out the surface.
So... one hour to disassemble it and a little more than an hour to reassemble it. It looked daunting to do at first, but believe me if you're patient and can follow instructions it is definitely doable. You don't need to be an HP tech to do it.
As for the parts, I obtained them from eBay. Apparently there are a lot of excellent condition used parts available from a variety of sources. I got the bezel for just under $30 shipped. Also, the speaker grille part is metal and tends to dent, so this time around I replaced it as well as the keyboard (the original was fine, but just a little touchy on one or two keys). With all 3 of these parts replaced, my laptop feels like new all over again. As for obtaining parts, you'll need to do your homework with the HP parts finder. There are many variants of the Pavilion laptop models with many parts in common, so the part you need can vary by number. The parts catalog can help you find them.
Anyway, that's about it. After having done this for the 3rd time, I figured there might be others out there with this problem on the brink of tossing out the laptop or selling it for parts on the cheap. It's salvageable!

Thank you for your information and support. I may have to replace my touch pad and keyboard and you have given me hope and confidence. Thank you again,

Left touchpad button delay in web browsers

I'm at a loss to figure out what could be causing my left button on my touchpad to delay intermittently. On both Google Chrome (whether stable, beta or dev) and Firefox, the left button when pressed may not respond for up to a few seconds. This is most noticeable when using Google Street View and Google Maps, which refuse to change viewpoint when holding down the left button. It isn't a Flash fault because there is also a delay when highlighting text.
I can rule out the possibility of any hardware fault as the left button on the touchpad works fine elsewhere, within KDE (ie. drag and dropping works without delay or fault) and other applications.

Hello kal33,
Welcome to the HP Forums!
I understand the left part of the clickpad is not working. To assist you, please try all of the steps in this HP document: Using and Troubleshooting the TouchPad or ClickPad (Windows 8)
If these steps do not help, then there could be a hardware issue. Since the computer is in warranty, I would contact HP phone support for hardware assistance. You can utilize this website to learn how to contact HP appropriately, based on your region: Contact HP Worldwide
Please let me know if you have any other questions or concerns. Thanks for bringing this issue to the HP Forums. Have a great day!

Touchpad button problem

Hi all,
A few weeks ago my MacBook (original Core Duo model) started detecting clicks on the touchpad button as double-clicks in the OS. This doesn't happen all the time, and seems much more likely to occur when I press on the left side of the button than the right, so I'm assuming it's a hardware issue.
Does anyone have a rough idea of how much it'd cost to get repaired at a UK Apple store? It's been out of warranty for a while unfortunately.
Thanks
J

I have two MB's one has a crisp trackpad button while the other had a mushy button. I fixed the mushy button quite easily. Take out the battery and look at the metal panel directly underneath the trackpad button. You'll see a circular indention in the metal. If you press lightly on the indention and at the same time press on the trackpad button you'll notice that the trackpad button's response is more crisp (at least mine was). I just pressed on the spot a few times to force the metal to bow every so slightly (not perceptible to the eye). Now my button clicks quite nicely across the entire button.

[SOLVED] Slow/sluggish touchpad buttons response (sometimes)

Hi all,
I have had this problem for some months now but have never looked into it, even if it is pretty annoying.
Sometimes (say one boot every three) the touchpad buttons of my laptop (see sig) behave strangely. Their response time is very long, I have to keep them pressed for ~half a second to make them trigger correctly.
This is very annoying when editing texts (selection a section of text with the touchpad) and using any click intensive application (ie editing a presentation with Prezi).
I use KDE and the only touchpad configuration I've ever done has been done via synaptiks.
I cannot tell after what update this started, it was too long ago unfortunately.
Since this happens only sometimes I don't even know where to start looking!
EDIT: I stress the fact that this happens with buttons, not with tapping

Just FYI,
this one solved itself some months ago after some kind of update.

EliteBook 8350p TouchPad Button issue.

The middle touchpad button on my EliteBook 8530p is not showing up under Mouse in Control Panel so I can't configure it to open links in a new tab when pressed. Any thoughts on how to fix this?

Hey shifty137,
Try re-installing the touchpad driver: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=3782359&...
Then, in the Mouse control panel, go to the Synaptics tab and see if you can configure the buttons there.

Hp notebook 15-n051sm (F4C10EA) Touchpad buttons hard to press

Hi, i bought Hp notebook 15-n051sm(F4C10EA) few days ago, from first moment noticed when you need to use touchpad buttons that they require quite good force for pressing them.
It isnt issue if you use short period of time but for longer usability it's annoying experience.
Had few Hp notebook before and never had some strange experience with touchpad buttons.
Is this normal way to use touchpad buttons of this Notebook models or it's hardware issue which would be better to send product back to seller?
Ty on answers in advance.

Satellite U400 - Is it possible to replace the touchpad button?

Hello
I need help please. I want to know if there is a possible way to change the button at my Satellie U400 because they are getting soft and they are not as good and hard as it was before, so please anyone know's if I can remove those and put 2 new one's?
If you dont understand exactly what I mean take a look at the picture and you will see/understand.
[http://oi56.tinypic.com/j0wwoj.jpg]
thank you.

Hi Loow,
Im sure its possible to replace the touchpad buttons because you can replace everything on a notebook. But I think its a little bit tricky because you have to disassemble a lot of parts and thats not easy.
You should ask an authorized service provider The guys can order new spare part for you and exchange it. Just write an email for example to get in contact with them.
You can find a list of ASPs here:

Macbook touchpad button issue

I recently bought a base model macbook. The touchpad button was placed more left than it should be, thus when you click the left part of the button, sometimes it rub the body and then not only generate annoying sound but also make the click difficult. Also the distance between the right side of button and the body is a little bit bigger than that on the left which makes the macbook looks wierd.
Does anyone know how to fix it (Probably just reposite the button a little to the right) easily other than send it to apple and wait?

Not sure that this is the same, but my Macbook's trackpad responds intermittently. After MB's in use for say 4 minutes, when I try using the trackpad, it doesn't respond. Always on the left. The left side of the trackpad is unresponsive!
Other problem is the mooing or purring of my optical disk(?).
I am thoroughly disappointed at the performance and these little kinks are annoying! Not to mention the service at the Apple store, from one employee telling me to open my window to let more noise in, in order to drown the mooing/purring sound to another bribing me to buy ProCare, saying only then would they swap the FAULTY Macbook.
Disappointed. Anyone have any ideas how to go about this one?

HP Pavilion DV6-1264CA Artist Edition 2 left touchpad button is screwed up

I'm a proud owner of an Artist Edition DV6 laptop, but a few months ago the left touchpad button suffered a bit of a failure. Through normal use, the left side of the left button (the one you use to click on just about everything) seems to have broken down. I am not familiar with the inner workings of this device, but it feels like there are two underlying supports that hold the button up and allow it to be clicked down on, one on each side of the button.
A while ago, the left side of the button started squeaking while clicking, and now it sags down, and the button can be rocked from side to side. The right side of the button is still up, and it now sits on a slant. Visually it is just a minor annoyance, but what is driving me batty is that now the button essentially "clicks" on its own. It can still be used normally, but often the button will click multiple times within a fraction of a second. I only use the laptop for entertainment, but it's still annoying as hell, especially when playing games where unintended clicking can lead to irreversible actions.
I have looked into the HP catalog for repair parts, but as other Artist Edition owners have discovered, there are no specific parts for the AE model, and the only relevant part is a complete touchpad with the whole palm rest attached to it. Of course, the palm rest doesn't have the Artist Edition graphics on it, which I absolutely intend to keep.
So I was wondering, if i can locate another palm rest with the touchpad, is the touchpad transferrable to my palm rest? Or is it inseparable? Are all DV6 touchpads the same? Or alternately, if I disassemble my touchpad, what are the chances that it is repairable? Maybe something just popped out of place?
Oh, and before you ask, the laptop is out of warranty, and I'm not sure I trust the clowns at Best Buy to be able to fix it, and to do so in a timely manner. I'd rather explore all options and see if I can fix it myself first.
Any help would be appreciated.
Thanks,
Phil

Does anybody have any input? I see tons of sellers selling HP DV6 parts on eBay, I just need to know if I can swap over a touchpad from one palmrest to another, and if all touchpads are the same in the DV6-7 range.

Touchpad button mode on Linux

Hello. How to enable the touchpad "button mode" on a Linux OS? (Ubuntu 13.04, specifically)
I'm talking about the possibility to tap on the "switch button" on the touchpad and then the volume control bar or the other six icons over it ([here's an [image|http://aps2.toshiba-tro.de/kb0/HTD9702NL0000R0105182.png] of the related configuration in Windows OS).
Even the chance of simply configuring custom tap zones would be useful. Is there a way to defining them?
Note: it should work on a Toshiba Satellite A200 too.
Thank you, have a good time.

Hi there
Some useful info may be found in the Arch Wiki: Link: https://wiki.archlinux.org/index.php/Touchpad_Synaptics

Touchpad buttons so hard

I just bought a new notebook dv2 1000ep to my wife, but I find the touchpad buttons so hard and heavy, needing so much pressure from the hand. It's almost impossible to work more that half an hour with the touchpad.
I own an older dv6510ep and the difference to my wife's dv2 touchpad is huge! My touchpad buttoms are much softer.
I wonder if this is normal to this model (dv2)? Or is a case of a faulty notebook?
Thanks
Jorge Domingos

I received my new DV7 laptop as a direct build to order from HP and from what I have seen so far, it is a $1400 DOWNGRADE from all my old HP computers. Function keys that were on the old laptops are not present, The touch pad is loud, VERY HARD TO USE, the curser is always off one digit, and often I have to click the touch pad many times to get the blasted thing to respond. First Hp computer I've had that I have been un happy with in 20 years, and I am UNHAPPY! HP, CONTACT ME IF THERE IS A FIX FOR THIS THING. I am so UNHAPPY that I have just sold the second computer I purchased on EBAY with the box never opened. This blasted thing makes my fingers hurt to use and i can't imagine my wife trying. Oh, and whatever chinese toxin you make the touchpad out of now leaves a very bitter taste on your fingers so you CANNOT snack or eat an apple and use the computer.

DV5-1000 touchpad buttons, premature wear

After about a year of using my DV5-1000, the silver coated left touchpad button began to wear through to the black plastic underneath. Also, the button became noticeably loose, especially when compared to the right touchpad button. It eventually got to the point where the button would click unreliably.
I managed to buy a replacement palmrest part for the DV5, which contains the touchpad assembly (you cannot buy the assembly separately). Unfortunately, the palmrest is an integral part of the laptop, requiring 75% of it to be disassembled to remove the original part. I downloaded a service manual and went to work... and I got it done after 2 long hours. The new part fit properly and the laptop appeared as new.
A year later, I'm faced with the same problem yet again! I am not abusive to the touchpad buttons. This kind of wear should not be happening. I dread having to take apart the laptop again... but I am worried that the button will start developing click problems as the previous one did. I wonder if some kind of protective coating added to the button would help it. Anybody else here suffer premature wear to the left touchpad button?
"If you keep an open mind, life will give you more possibilities."

I had a look at some of the newer DV5 models and... I'm rather taken aback with how HP solved the touchpad button problem. They no longer have tactile keys. Instead, there's a soft touch membrane. This makes it very difficult to control sustained pressing of the button, as the travel from on to off is so short. It was a real cop-out in my mind, that HP didn't stick with tactile buttons. Sure, there were some problems with how they were intially implemented, but c'mon--so many other laptop makers have tactile buttons that don't wear out. Why couldn't HP have gone that route of just improving the button?
Also, what's with all of the wacky patterns that HP is now slathering over their laptop casings? It makes the laptop look a lot less professional. If they want to appeal to kids, make it so that there's an optional shell you can get with the laptop with whatever zany pattern you wish. Or instead, just opt for something conservative and wear resistant.

T430 right touchpad button stuck

Hello,
I'm not sure whether this issue has been talked about here, but i can't find anything on the subject anywhere.
My T430 right touchpad button gets stuck whenever i press it (by stuck, i mean mechanically stuck). Is there anyone else with the same problem?

Hi,
Welcome to Lenovo Community Forums!
I’m sorry to hear that right click button of the touchpad got stuck in your Lenovo ThinkPad T430.
In some situations dirt, hair, dust, etc. can obstruct the buttons causing them not to work. Try to insert a sheet of thick paper under the button to remove the dirt that can be stuck there.
If you are confident enough, you can open the laptop to reach under the touchpad, clean and do a proper reseating. Refer the hardware maintenance manual to understand how to reseat the palm rest assembly.
Hope this helps!
Best regards,
Mithun.
