    The memory of my Razer Blade 14 has been slowly increasing over time to 100% due to a memory leak. After tirelessly searching for the problem, I have found it to be SynTP.sys, the Synaptics driver. Has anyone else had this problem? To test (without downloading poolmon):
    Go to Task Manager
    Click on the Performance Tab
    Click on Memory
    Watch the Non-paged pool
    When not moving the mouse, it should remain constant at a relatively low value.
    Now, move the mouse around with your touchpad rapidly. If the non-paged pool value increased (for me, around ,5MB/s), then the Synaptics driver is causing a memory leak. I have confirmed this leak for myself using poolmon from the Windows Driver Kit.
    Any ideas on how to fix this? I was going to install new drivers, but I need to wait until I have access to my mouse again. And does anyone know where to find new drivers? The drivers on the Synaptics website are older than the ones that come preinstalled on the Blade.

    I had a 100% memory issue too, but it doesn't happen all the time. If it goes up again, I'll check and let you know if it is Synaptic too !

    Hey there,

    I thought I would post a reply to your issue. While I do not have the Razer Blade 14, I have an XPS 12 (Haswell) with the Synaptics Touchpad Driver (16.5.0.42, A02).

    The Non-Paged pool keeps climbing until the system memory gets to 99% and my Laptop becomes unusable. Once I reboot the system goes back to normal but the Non-Paged memory pool keeps increasing. Here are some screenshots:

    It takes 12 hours for the memory to go from 0% to 99%. Eventually the system runs out of memory, then it starts using Virtual Memory which slows down the system even more.

    The Non-Paged memory is caused by the Synaptics Touchpad driver. Poolmon clearly shows this. Without the driver, there is no memory leak what so ever.

    I contacted Synaptics but they really do not seem to care about the issue.

    Exact same. If it takes 12 hours, I'll get I'd better not use my computer for too long and restart it every 4 hours or so (which is quite fast with the Blade!). That's still sucks though...

    I'm having the same problem as well. Wish I came here first, it took me a while to track it down to the Synaptics driver.

    I tried a few generic Synaptics drivers, but none of them seem to work with the Blade. Uninstalling the driver works of course, but there's a definite loss of precision, not to mention all scrolling and gesture features. Left alone, my non-paged pool will slowly increase in size, until I eventually have almost no memory left. It doesn't take long for the loss of memory to start impacting performance, and if I leave the laptop on overnight it will eventually blue screen and restart when memory runs out.

    The only way I know of to reinstall the Blade's Synaptics driver is via Synapse, it's not even posted on their support page. So if there is a driver update, someone please communicate it here. There's no easy way to know otherwise. And hopefully Razer comes up with a solution soon, a memory leak is a fairly serious and debilitating problem.

    I have opened a support case with Razer regarding this issue. I doubt I'll get much of an answer right now, but hopefully enough people will complain to at least make them aware of the problem.

    Got a positive update from Razer today. To quote the relevant portion:

    So they know and it'll be fixed (hopefully) in a month.

    That is good news! So we will be able to download new drivers off the web site once the update is available?

    I'm also interested in having these memory leaks fixed. I'm more worried about them than I should be. As with a few posters above, I'm actually an XPS 12 owner.

    btobey, I can see from your sig that you're also an XPS 12 owner, and unfortunately it seems that "Synapse" is something specific to Razer laptops and not actually related to Synaptics in general. I think us XPS 12 owners are gonna be stuck with this memory leak for a while to come.
