    No granular brightness level below 60%

    This is my third Surface Pro 4 unit after having returned the previous two because of shaky/ghosting screen display. What I notice with this unit is that below 60% the screen brightness remains the same regardless of which level specified with Fn + Del/Backspace. Anybody else encounter this...

    Booting from 3rd-party CD

    Ah never mind, I now remember what I did from the Acronis discussion thread nearly two years ago. Restoring Microsoft Surface Pro 4 | Acronis Forum While I can't tell for sure what conditions make the CD boot media bootable (even if failed half way), the critical means to work with a Surface...

    Booting from 3rd-party CD

    So I tried some other build, setting the BIOS boot priority to USB storage Internal Storage Windows Boot Manager Connect optical drive direct to its USB port instead of via hub (but that means leaving out backup disks also connected via hub) In one instance, the Acronis boot loader actually...

    Booting from 3rd-party CD

Previously when I experienced screen image ghosting in the...

    Wobbly type cover trackpad

    Well I live in Singapore, region with high humidity. The fan is merely blowing air in my room/home, which I shallowly assumed wouldn't be a so much of a difference simply by circulation. I'm not sure how I can conveniently test the property of air when it's still versus rapid movement.

    Wobbly type cover trackpad

    Strange as it may seem, I suspect, this has something to do with my standing fan in the room. When it's switched on and blowing air in my direction at the desk, there seems to be disruption to the sensitivity of the trackpad - wobbly, jumpy mouse pointer; or sometimes can't detect my finger and...

    Wobbly type cover trackpad

    For quite a number of months this year, something strange has happened to my SP4's type cover. When I'm carrying it around mobile, the trackpad works steadily. But when I return to my desk, where I have a bluetooth Sculpt Comfort mouse to use, the trackpad sensor goes rather haywire and sends...

    What causes wireless adapter to prefer n over ac?

    If I am to make a guess, the adapter likely prefers to 2.4Ghz network because the signal strength's better. Some times even by a quarter. (the icelava networks)

    What causes wireless adapter to prefer n over ac?

    The sucky thing about the router interface is it list wifi protocol to distinguish between ac (5Ghz) and n (2.4Ghz) clients. Heck, it doesn't even differentiate between wired and wireless clients in the network. Its wireless setting also does not include any granular control over 2.4/5Ghz...

    What causes wireless adapter to prefer n over ac?

    I don't need an extra wireless network adapter; the internal adapter can connect over ac, but only when I force it to use 5Ghz only. If set to Auto, it prefers to communicate over 2.4Ghz (n). I wish there was some sort of wireless network negotiation log to inform what transpired between adapter...

    What causes wireless adapter to prefer n over ac?

    I cannot use the router's standard firmware; my ISP implements IP TV via a separate VLAN so a custom firmware (provided by D-Link themselves) is required to make the router aware of VLAN segregation. I do not suspect the custom firmware would change wireless functionality/behaviour since it was...

    Does anyone have a screen flickering issue?

    Mine did not flicker. Within around three months of acquiring the SP4, I noticed black horizontal lines across the top part of the screen (essentially striking out title bars). Then the WHOLE screen display might ghost previous rendered frames. If I was watching a video at that time, it's...

    What causes wireless adapter to prefer n over ac?

    My home route is a D-Link DIR-890L. Since the beginning on acquiring the SP4, I noticed wireless speed to be rather slow, and later discovered that the onboard Marvell AVASTAR Wireless-AC Network Controller connects to the router using 802.11n. I could only acquire 802.11ac connection if I...

    Out of sync video and audio

    Ever since some driver/firmware update in the last quarter of 2017 (I cannot pinpoint which), I noticed that my SP4 tends to playback videos with audio out of sync (i.e. audio happens before the video) whenever I pull video data via the wireless network adapter. It doesn't matter whether I am...

    Surface Pro 4 Screen is flickering, overlapped

    Have this problem, on my SECOND unit. AGAIN. It's likely a heat problem, so gotta find ways to cool down the top area of the device. Surface pro 4 screen shake, freeze, horizontal lines across the screen
