Samsung Series 7 Chronos NP700Z5A: Trackpad Discussion Only

The thing is it DOESN'T (my center clickpad) work with the newest driver

 

You can look through the registry settings to see if there's an option that you have to enable.

I already check it out, but I have no idea which one is the right key.

 

Hi, I just got the NP700Z5C-S02UB from Best Buy. I have a problem where sometimes when the laptop comes back from Sleep or from idleness the trackpad becomes completely unusable. It's barely responsive and the 1-finger touch clicking doesn't work at all. Physical clicking of the trackpad hardly works too. I have to repeatedly press down in the same spot several times for it to finally register. I'm not sure what the problem is, I thought it was a bad install of Windows 8. I replaced the old hdd with an ssd and installed Windows 7. Installed the latest ELAN drivers but the problem is still there. Restarting the laptop doesn't fix the problem. The only way to get rid of the issue is to shut down the computer and turn it on again. At first I thought it was a software issue but now I'm beginning to think it might be a hardware defect but I'm not sure if that's possible.


EDIT: Nevermind, Ended up exchanging it. New one works perfectly now.

 

My issue with the trackpad is scrolling in third party applications. The trackpad sensitivity seems perfect in Windows but in some of my third party programs it is awful. I use Sony Vegas 10 and scrolling is used to zoom. For this you need precision and it isn't smooth at all. Sometimes it won't zoom at all as if it doesn't register me touching the trackpad at all and other times the zoom jumps by huge margins. I can't use the trackpad at all for editing audio and video. Another program I use all the time where scrolling sucks is ACT by Sage. The same thing happens as I scroll through my contact list and again it's totally worthless.

However, in Windows folders it is perfect and in Google Chrome it is perfect. Perhaps something about older programs is the cause of this issue. Unfortunately I had no intention of upgrading these programs anytime soon.

 

I am seeing this too in some older applications. Particularly in one charting application I use a lot (TradeStation) two-finger scrolling only "takes" after several seconds, which is very frustrating. I have not been able to determine why or find a solution. I mostly use this program with a mouse, though.

TradeStation also has problems with Microsoft mice that have a smooth scroll wheel. I have to add it to the list of "program that don't scroll correctly" which makes the mouse driver treat it as if it were an old, non-smooth scroll wheel.

Maybe this is a clue to what is causing the touchpad problem in some programs. Just a thought...

 

How did you get "Reverse Scrolling" option to show up? I have 11.7.2.1 installed and don't see that option.

 

SW Update is now offering me Elan Touchpad driver 11.7.5.5.

Edit: I have installed it. No obvious differences in the user interface.

John

 

I'm having the hardest time finding the older version of this driver! I updated a while back, but never configured my personalized settings.

When I tried to tweak it, I found that many options have been removed since the previous version of elan software. In particular, I want the ability to reassign the click buttons at the bottom of the touch pad. The touch pad seems to be more glitchy on this new version as well.

I dealt with it for a couple of weeks because I'm lazy but it's really starting to drive me crazy when I'm working in things like excel.

Samsung is no help, as they only have 1 version of the driver hosted, and it's the latest version. Has anyone had any luck rolling back to the old version?

 

So anybody know how can I activate the "Reverse Scrolling" option in the settings? I've played around with the registry settings and had no luck.

 

John,

I couldn't find this update on the SW update, would you mind uploading it somewhere please?

thanks

 

SW Update is offering it for my Series 9. Anyway, I decided that it is a step backwards for me with left click + select being very erratic so I've gone back to 11.7.2.1.

The Update file is ~250MB so I'm not going to try to do it here. If you still want the new driver later in the week I can look into uploading it.

John

 

I found 11.7.2.1 through the Software Update, I kept trying different models till I found this version of the driver.

I went to My Product --> United States --> Series 5 --> NP540U3C-A01US --> Windows 8

And found it there...

 

Since Elan touchpad driver 11.7.2.1 is now hard to find, I have uploaded it here. The 150MB installer is Win 7/ Win 8 32/64 bit.

John

 

When I'm playing a game I can't move my cursor when I'm just walking. How do I fix this? I'm using the newest Elan touchpad driver. Also, I set my "Disablewhentyping" to 0 in regedit.

 

Thank you for uploading that John.

If (for any reason) somebody would rather download from Samsung, I found last night that the Elan 11.7.2.1 driver is still listed in SW Update under my model (NP700Z3A-S03US). It's been there since I downloaded it Nov 10.

 

Anyone got the 10.7.5.0 driver?
I want to disable tapping and use only the clickpad.. Don't work on any newer drivers.
Or if anyone knows the values in registery for making it work.

 

I don't seem to have that problem with my NP700Z3A and driver 11.7.2.1.

Anyways, I googled "samsung touchpad 10.7.5.0" and got a number of hits, the first one being this softpedia one: Download Samsung NP700Z3A Notebook Elantech Touchpad Driver 10.7.5.0 Driver for Windows 7 / Windows 7 x64 - Softpedia

I didn't try actually downloading though.

 

Does anyone else have the problem that the touchscreen driver doesn't seem to switch off the one finger drag and drop ? I'm constantly moving things around which is really really annoying.

I'm quite sure that somebody else posted that issue somewhere in this forum, but i just can't find the post (which may would lead to a solution) :/ .

 

Within the touchpad driver installation package there are two different configuration utilities: ETDSimpleUI.exe and ETDAniConf.exe. Extract these and put them somewhere. You can then try using both to make your change. There's also the possibility that your security settings are preventing the utilities from actually changing the registry settings in which case try running the utility via right-click > Run as Administrator.

John

 

Is there just a way to disable the touchpad by default? I know I can turn it off and on by the hotkey, but I find that if I turn it off, then hibernate, then wake, the touchpad is turned back on. I like the option of turning it on by hotkey, but would like to default it off.

 

I´m having this problem driving me nuts! I´v disabled drag-and-drop, but it still does it all the effin´ time.

 

fffffffwwwweee. I got a mail with instructions on how to return my 900x4c, and then 25 minutes later I got an update for the trackpad from SWupdate. Now it´s working better than ever. I´m happy about this!

 

what version of the touchpad driver did SWupdate offer you to download?

 

Seriously, noone knows if or how the touchpad can be disabled by default? I am surprised I might be only person to want that.

 

You can disable it in Device Manager.

John

 

I recently purchased the 15.6" Samsung Series 7 Chronos (NP700Z5C-S04CA)
The laptop has been great except for one problem. I've been having an issue where left clicking (physically pressing not touchpad left click) will randomly stop working.
Is this an issue with the laptop itself?

On a side note: The left side of my touchpad is a bit pushed in more than the right side. Reviews on the laptop that I've read said they have the same issue where one side of the touchpad is pushed in more than the other.

 

It's more likely an issue with the driver. Are you up-to-date (run SW Update to see what it offers)? Also check the BIOS.

There's been a few reports of that problem. You can ask retailer to replace the computer or ask Samsung to have it fixed.

John

 

All the drivers are up to date. I had everything update through SW Update without failure. What I was thinking is that since the touchpad was pushed in more in the left side then the right. That, that was causing the left click issue.

I'll probably get the laptop exchanged or fixed, and if the same problem continues to happen then I'll know for sure that it's most likely a driver issue.

 

Is the random operation related to where you click? Is this the area of the left button or anywhere on the pad? Are you missing the physical audible click or is that touching the pad doesn't register? If the last then it might indicate a need to adjust the sensitivity.

John

 

Yes it is where I click, it's the left physical audible click button on the bottom left corner. The touchpad left click registers fine.

 

I'll support your view that there is a mechanical defect, perhaps associated with the left side being depressed.

John

 

I thought I'd take a shot and see if anyone has any ideas that might help me out. I've posted on here before that I have to use old drivers for my trackpad to work correctly. I'm using windows 8 now however, so the older drivers aren't optimal.

The problem I have with the newest drivers is that when I try to two or three finger tap, it misses most of them. If I touch it slowly and very gently it picks it up consistently, but when I try as I normally would it misses about half of them. I appreciate anyone's help in finding a solution. Thanks.

 

Have you tried using the control in the newer drivers to adjust the sensitivity (strictly speaking, the control panel is not part of the basic driver but is in the installer package - look for
ETDSimpleUI_Win8.exe which you can run by itself).

John

 

Yeah I've played with both the sensitivity and the palm tracking. Neither seem to be doing anything that is helping my case. Thanks for the suggestion though, I probably should have mentioned that I tried this earlier.

 

I recently got my laptop exchanged for a new one and the same problem continues to occur. Unfortunately the left side if the track pad is still depressed so I can't tell if it has anything to do with that anymore or if it's driver issues.

 

Just got my Series 9 13,3" today. Unfortunatly I got some of the same problems as many of you here.

Mousecursor jumping all over, marking stuff, random clicks etc. almost always with powersupply hooked up, more stable without powersupply.

If you got this problem it is hardware. There is a groundingproblem with the trackpad somehow. I can replicate the problem very easy.

1) I disconnect the powersupply.
2) I uninstalled the ELAN driver only running on microsoft PS/2 mouse settings to eliminate driver issues.
3) Then I position myself so that I had little ground like lifting my feet of the floor just sitting on the chair, or sitting with the computer on the bed to pronounce the problem.
4) I placed one hand on the chassi, like on the wristpad left of the trackpad and with the other I moved the mousecursor with one finger only touching the trackpad. Mouse works pretty fine!
5) Now I removed the hand off the chassi, only touching the trackpad and move the cursor and what happens ... irratic movement ... now I put back the other hand onto the chassi again and the cursor movement calms again.
6) I try the same with powersupply on ... the effect above multiplies by x5.

As soon as I "ground" the computer with my other hand touching the chassi while touching the trackpad, the problem goes away, If I only move the trackpad without me being "grounded" the problem arise, especially with powersupply hooked up. Above test is very concistant for me and I can only conclude a hardware problem somehow.

 

I have the same problem with touchpad on my new NP900x3c. I tried a different AC Power Adapters. The issue is permanent. Mousecursor is jumping all over with power supply pluged in. It is enough just to put finger on touchpad and mousecursor is "dancing" on the screen. I read on Russian forum that many people have the same problem. The best way is to hold your second palm on the bottom part of laptop. Samsung has no answer for this issue. Many people think it is a hardware electrostatic issue. I agree. For now there is no solution only like to get a refund or use an external mouse when you run on ac adapter.

 

Could be electrostatic, but I doubt it. If it where a material issue it would happened to almost anyone, and it doesn't. And it would be inconsistant while static build. My problem at least was consistant.

I suspect its a manufacturing problem. Something causes bad grounding within the design and a small current is leaking thru the trackpad. When you provide a path for the current, eg when you touch the chassi, you essencially provide grounding. It probably would work as well if you would touch any other large metal object, like a radiator, instead of the chassi to provide a ground that way.

Groundingproblems are notoriusly hard to find. I could be that the trackpad itself is badly grounded for some reason, but it could also mean any other component connecting to the trackpad has bad grounding, like a pcb. And a low current is leaking thru the trackpad. The effect would be there all the time, but as I suspect, the computer uses a higher current when on AC charge it would show worse when AC is on.

It could be that the compact build (on the Series 9 atleast) requires very narrow margins of error in construction and some computers are falling outside of this margins. It's a design flaw corrected with a larger margins or a Q&A flaw in construction, nither something I suspect Samsung would admit to anytime soon.

The most probable reason, since it is a problem on more then one computermodel is that the problem is in the trackpad construction itself.

 

There's a lot of metal in the Series 7 and Series 9 notebooks so it's difficult to isolate any mains power problems from the users.

Two things I would test:

1. Use one of the mains testing screwdrivers to see if ground is properly grounded or has some floating voltage. Also see if neutral has a significant voltage on it.
2. Try using the computer on mains power with the ground disconnected (eg via a 2-pin adapter).

I urge everyone to have a look in this thread: http://forum.notebookreview.com/asus/689932-new-elantech-asus-smart-gesture-drivers-how-they-4.html

There's a new driver available that is from this month, and it finally (after half a year) made my trackpad worthwile and easy to use, comparable to my friend's macbook.

i haven't experienced the ground leakage issues so for me it finally fixed everything.

optimal settings for me are: palm tracking on max. sensitvity on the 3rd setting from the left.

 

I tried the driver that flying_troubadour recommended and it didn't fix my problem, it seems the same as the predecessor to me. Thanks for the tip though flying_troubadour.

I'm kind of annoyed I have to choose between an older driver where gestures like swiping three fingers down will not work, and the new driver that is constantly missing two and three finger taps so that I have to try multiple times.

 

The new driver is nice with inertial scrolling, but it seems like slow scrolling is less accurate than my previous driver which was 11.7.2.1. It also lost the nice feature of dragging and dropping with two different fingers. I may revert, but we'll see.

 

, I have a Series 9 NP900X4C. Just spent the last two hours trying to get some of the above trackpad drivers working eventually had to resort to a system restore to reinstall my old version.

I am on 10.7.16.1 and it works great except it keeps deactivating itself, and I have to keep reactivating via control panel. I've tried some of the above 11.... versions but they just don't work at all. They seem to deactivate the trackpad buttons and tap select just doesn't work making it impossible to use at all. I like this laptop, but this is a right royal pain in the ....

 

i have an np700z5a and i am not able to use the trackpad while pressing a key.
i modify all the damn windows registry, but is not working
is there any other thing to fix this???
the more i use this laptop, the more i regret buying it

 

If you set PalmCheck to minimum in the driver settings you should be able to hold W (or any other single button) while aiming, but you can't press more than one keyboard button at a time and still expect the mousepad to work. It's designed so that you don't accidentally move the cursor while typing. Until ELAN releases a driver that completely disables keyboard press detection, you're out of luck.

 

Okay, I just purchased the samsung chronos series 7 (NP700Z7C-S03) last week Friday and today I went back to memory express with the intentions of returning it because of how faulty the trackpad is. I found that the left button would often register as the right, the pointer would freeze and when typing or selecting all kinds of weird selection of pointer leaps would happen...an incredibly frustrating experience. In addition to these malfunctions, I am a designer and use adobe CS programs often. Not only did the trackpad make the programs unusable but the hand tool keyboard shortcut in photoshop (or any of the other programs) just did not work.

I found out today that this was due to a keyboard freeze functionality that the trackpad driver automatically initiates (so that when you are typing you dont have the pad jumping around). Not alot of good that this did me since while typing the pad would still malfunction and select things randomly.

SO I fixed the problem by removing the driver completely (ETDWare X64 11.7.5.5_WHQL - ELAN Microelectronics Corp.) from my programs and now I have a trackpad that works like it should. Granted this solution may not be the best solution for everyone as now I do not get the keyboard freeze functionality, but I have found a work around this too - I simply hit FN f5 to turn off the trackpad when typing for long periods of time and I don't have the cursor jumping all over the place. If you find that removing the driver is not what you wanted you can always just reinstall it and continue using it. For me, I find that it creates a lot more problems than it solves and until ELAN Micro comes up with a better driver that actually functions properly I have no desire to use it at all. Hope this helps.

 

I'm using version 11.7.8.5 from this thread, and it seems to improve the experience somewhat.

 

Hi Please can you help.

I just bought the NP700G7C S02 UK. I have a disability and RSI, this touchpad is a real pain to use, quite literally. I am using the latest drivers, which only allows two finger scrolling.
I would be much better off with one finger scrolling, is there anyway of achieving this? Could I rollback to a driver where one finger scrolling existed, or is there another way, like alternative drivers or something?

Thanks.

 

v11.7.8.5 has one finger scroll.
