USB 3.0 Ports Shows No Sign Of Connection Like Blinking LED After Upgrading Laptop

Aug 20, 2015

I had recently clean installed Windows 10 on my laptop. Before doing that, all my drivers were working well except for WiFi - a problem since build 10158. Currently I am on build 10240.

When I plug usb sticks into the USB 3.0 ports on my laptop, they don't connect. It's not like the 'not recognised' problem. It simply shows no sign of connection like blinking its LED or any response from the OS. On the other hand, when I connect my Lumia phone in the same ports, it warns me of Slow Charging.

And when I plug it into the 2.0 port, it gets connected. Why is this happening? All of my device drivers are up to date. I believe its not a hardware issue because my laptop has two such ports and both of them have the same problem.

USB Ports On Right Side Of Laptop No Longer Recognize Any Device

Oct 15, 2015

I installed W10 yesterday and now the USB ports on the right side of my laptop no longer recognize anything.  I don't even get the message that the laptop knows something is plugged in.  There is a USB port on the left side of the machine that is working fine, but the ones on the right are ignoring me completely.

Networking :: After Upgrading PPPOE Connection Stops Internet From Working

Jan 11, 2016

I did my upgrade quite shortly ago.Basically before that upgrade I had 2 connections at the same time: Local Area Connection with Ethernet and my PPPOE connection as advised by my provider.I've been using my PPPOE connection for years to sidestep some connection issues especially with uPnP, but now my internet only works through Ethernet and when I also start in my dial-up section the PPPOE connection, Windows 10 reports the "no internet connection" problem.After using "Troubleshoot problems" it resets the required parts and reports solving "Gateway is not available" problem.

1)I've already tried to reinstall all network drivers by deleting them first with device manager and through netcfg d in command line.
2)I don't know if it works but my BitDefender reports new adapters upon starting PPPOE: Teredo Tunneling and 6to4
3)I already tried to set Local Area Connection to Home and my other connection to Public and also all other possible permutations of settings

Date No Longer Shows On Taskbar After Update On Laptop

Sep 2, 2015

After a recent Windows 10 update on my laptop and my work computer the date no longer shows on the taskbar. The clock is visible and the calendar pops up when you click on it, but no date. No settings were changed by me and everything is enabled as far as I can tell. Is this just some sort of glitch or is there something I am missing to bring the date back?

Laptop Boots Up To Black Screen With Cursor - Shows Signs Of Activity

Oct 8, 2015

I am trying to figure out what is going on with my mom's laptop. Two days ago she told me she was using her laptop and everything was fine, but then she left to do some things in the kitchen and came back a bit later to the screen off. Upon waking it up by moving the mouse, all she got was a black screen with a white cursor. I have looked at it and upon manually restarting, it shows the Windows 10 logo, and then it goes to the black screen with the cursor. There is no login screen either but I do also hear the welcome music. One thing I noticed though is the cursor does have the blue loading circle next to it like it is actually still doing something, and it flashes and spins now and then, as well as the computer sounding like its working, but I have left this on for almost 40 minutes now and it is still just a black screen. It sometimes goes to the off screen and have to move the mouse to wake it up again. Some people online suggest task manager and opening up other windows but nothing works, I can just move a cursor.

Networking :: Direct Wire Connection Between Laptop And Desktop?

Feb 10, 2016

On Desktop computer have OODLES of storage and multi-media file but slow Wifi card.

Laptop (new) has mega fast Wifi - AC 5GHZ. Almost as fast as LAN.

Want to chromecast some movies to a TV in a friends house.

Can I direct Wire the laptop to the desktop so I can share the multimedia files and then use the laptops fast Wifi to beam it to the remote TV via chromecast.

I can't run Lan cables all over the place - but if a direct connection can allow me to use the WIFI adapter of the laptop then problem solved.

What sort of cable do I need -- I don't believe you can just stick a bit of Lan cable between the two computers (or can you).

Years ago there was a thing called LAPLINK -- relied on old serial COM ports --that would be too slow - and in any case no COM ports on these computers.

I don't care if it's "Heath Robinson" --it's not a permanent setup - but we want to watch a load of movies etc and his wifi isn't fast enough (the ISP internet service is superfine and his router is capable of high wifi speed), --We've been banished to his shed where the computer is - because the women want to do something else !!!!.

Note - normal sharing works but is a bit of an abysmal failure since I can only get about 500 Kbs -not Mbs !!!!!) from his wifi card on the desktop so normal sharing is TOO slow. The data won't get delivered to the laptops wifi fast enough to watch the movies without re-buffering every few secs - especially if it's 1080p with subtitles that usually need transcoding on the fly).

Black Screen When Booting Laptop After Upgrading

Jul 30, 2015

I have a dell insperation and after having upgraded to windows 10, I came across a few issues. The update when well and windows 10 is working on my laptop, however, I have an issue where I am presented with a black screen when i start my computer. I do see a dell screen and a windows boot screen before it goes black so i know the issue is not a hardware issue, however after the windows boot screen passes (the one with the blueish window icon) the screen goes to black, but it is still on (meaning the monitor is still turned on just not displaying anything). The reason i know that windows installed fine is that external monitors do work, just not my laptop monitor. I have already reinstalled windows 10 and have made sure all my drivers are up to date. Windows 10 is just not recognizing my laptops screen as a usable monitor.

Laptop Suddenly Went Black Screen After Upgrading

Aug 5, 2015

I recently upgraded my laptop from Windows 7 to Windows 10 64 bit and shortly after it was completed, everything was working fine until the screen suddenly went black. The computer was still running but I could not see anything on the screen to restart the computer so I closed the laptop so that it would shut off to sleep. Coincidentally a power outage happend lasting for about an hr after. When I am finally able to boot up the computer, it show the ASUS splash screen and the windows logo with the loading spin cycle but then shows a black screen after. My guess is that the OS may have been corrupted or something so that I plan on backing up my hard drive before going to a tech shop. I'm not sure what the issue is but it seems like I may have to reinstall the operating system. i have an ASUS N61J. I can't boot into bios or safe mode and can't get passed the black screen to log into my user account.

Laptop Won't Switch Off Or Restart Properly Since Upgrading (10074)

May 17, 2015

I recently started trying out Windows 10. It's buggy and frustrating, but it's still in preview mode, so... That's expected.

Nothing was working when I installed build 10074 off disc, so I installed build 9926 off a disc (I got the iso from MSDNAA, I'm a programming student) then upgraded via settings to 10074.

During the upgrade, my laptop started resetting, normal. But halfway through, the resets stopped working.

The screen switches off, the cd drive switches off and the hdd activity light switches off, but the power stays on, and the fan keeps running. It also doesn't switch off on shutdown either.

I finally have a working version of Windows 10, minus Cortana and Spartan (I'm in Aus), but now my laptop won't shut down.

Could it be drivers? Is it OS interference? Is there a way to fix it without uninstalling and re installing Win 10? I really cbf going through all that again....

Drivers/Hardware :: Lost Audio On HP DV6700 Laptop Since Upgrading

Aug 8, 2015

Lost audio on HP DV6700 laptop since upgrading to Windows 10. Ihave removed sound device from device manager and reinstalled, have replaced driver with previously saved W7 driver....still nothing, not even the windows system sounds, critical battery etc.... All seems eps ok except this.....saw a post that says the sound is integrated with the graphic card, but the graphic card now has a windows 10 driver from nvidea.....maybe should downgrade GPU with W7 driver...

Just tried the idea of setting frequency to 16bit 9600 but I received no sound output error box....then went to enhancements settings where it has bass etc etc settings, was disabled so enabled it without choosing any option..then went back to frequency and changed it to default, which is 24 bit 19200....then was told not supported by this device but then miraculously it worked....now have all sound restored windows music everything...not sure if still have windows 7 driver...it is MS 2008... really scared to update the driver as it is all now working....not sure how I fixed it though, was it one particular action ? or a combination...?
