I had a client call me up saying their near new Intel i5 10th Gen Nuc was occasionally coming up with "WARNING: System has recovered from an over-temperature condition" for no apparent reason. The system was not being stressed in any way.
First thing I did was to load Cpuid HWmonitor, it's an excellent tool to check the various temperature sensors throughout the system. Running a 4k Youtube video quickly pushes the temperature to reach close to 100 degrees.
Upon inspection, the fan and heatsink were free of dust or other obstructions. I also checked the bios settings for fan optimisations, setting the fan speed to "cool" really didn't make a big enough of a difference.
How to fix Intel Nuc - System has recovered from an over temperature condition
After spending many hours on this I came to the conclusion that the problem was not fixable an an RMA would be necessary. If you have this issue then get in touch with Intel to arrange an RMA - if your NUC is still under warranty.
If your NUC is no longer covered by the Intel warranty then you can get passed the problem by disabling the Intel turbo boost option in the Bios.
Enter the Bios using the F2 key at startup then navigate to Advanced and uncheck the "Use Turbo Boost" option.
Windows users across the globe that use Kyocera printers have had a blue screen pop up when trying to print after installing Windows update - KB50000802.
Windows updates - got to love em. If they don't steal your time loading and slowing down your pc they add blue screen errors to the list. Although essential to the security and stability of our Windows pc's, the last thing you expect is for it to cause instability.
Windows users that installed the Windows "KB50000802" update will get a blue error screen. The blue screen stop code "APC_INDEX_MISMATCH" "Win32kfull.sys" comes after trying to print to any of several models of Kyocera printers. The error can not be resolved by updating the Kyocera printer driver.
How to fix "APC_INDEX_MISMATCH" Windows blue screen error
The fix is pretty simple really, just uninstall the Windows update "KB50000802"
Do this by going to "Settings" click on "Update & Security" click on "Windows Update"
Click on "View update history"
Check to see if the update "KB50000802" is listed, if it is, move to the next step.
Click on "Uninstall updates"
Select "Security update for Microsoft Windows (KB50000802)" then click on uninstall.
Once the update has been uninstalled you will be prompted to restart your computer.
As a further step I recommended to pause updates for a while until Microsoft releases a fix.
On the "Windows Update" screen go to "Advanced options"
Go to the "Pause updates" section
Choose a future date to pause updates until that day. I suggest two or more weeks.
A while back I had to put together a mid range gaming computer for a client, the client had a set budget in mind and I had to spec out a good bang for buck gaming computer. The client's only demand was that the cpu had to be an Intel i7 10700.
The parts list included: Intel i7 10700, H470M motherboard, 16GB DDR4 2600Mhz memory, GeForce RTX 3070, 650 Watt PSU and a Samsung 1TB M.2 NVMe SSD drive. The build was an absolute pleasure, everything went together like a glove. I assembled the system with the stock Intel cpu air cooler that came included with the Intel i7 10700 cpu.
Stock Intel i7 10700 CPU Cooler
The Intel i7 10700 desktop cpu is an 8 core 16 thread, 2.9GHz clocked cpu that can turbo boost to 4.80GHz and in the process consume up to 215 Watts under full turbo boost load. The 14nm Comet Lake processor has a max die temperature of 100 degrees C. The included cooler is certainly good enough to run at the processor 65 Watts TDP but not more, when turbo boost kicks in the cpu die reaches 100 degrees C in mere minutes.
When it came to testing the system, I ran a few benchmark applications but my go to was Call Of Duty Warzone as this game is CPU and GPU intensive. After a few minutes it was evident that the stock cooler is NOT sufficient. The cpu was cooking, the cpu package temperature was running at 93 degrees C! "CPUID Hardware Monitor" recorded max temperature hitting 100 degrees C - That's the Cpu max temperature as per the Intel specifications!
Best Value CPU Air Cooler - Cooler Master Hyper 212X CPU Cooler
The Cooler Master Hyper 212X CPU Cooler comes with all the necessary mounting gear, thermal paste and even a tool for tightening the bolts that are included in the box.
I swiftly removed the stock intel cpu cooler and replaced it with a Cooler Master Hyper 212X CPU Cooler. Mounting the cooler was fairly straight forward and the entire process took about 10 minutes. The Cooler Master Hyper 212X CPU Cooler 212X is amazing value for money. Running Call Of Duty Warzone with the same settings in the same ambient temperature of 26 Degrees C see the temperature drop down to a respectable CPU package temperature of 71 Degrees C, that's a massive 22 Degree C difference! Very impressive for the price!
Some years back I had an attempted break in on my property which prompted me to look into an IP security camera. I did not want to spend a load of cash and wanted something basic. I settled on and installed a Sannce IP camera to monitor street view access into my property.
From the get go I had issues with the Sannce App not connecting and draining my cellphone battery a lot quicker than it should. I did some tinkering and found that the Sannce IP camera can be accessed via web interface, therefore negating the need for the App.
Accessing the Sannce camera worked ok but there were functions that were not working well with the camera. Playing back automated recordings was a pain in the butt, I was never satisfied with how it all worked.
Fast forward a couple of years and I finally decide to look at a different camera. I had some specific criteria for the new IP security camera:
Should be easy to install
Does not require any wiring
Works off Wi-Fi
Can record locally to an SD card
Has an easy to use app that DOES NOT require monthly subscriptions
Should have good image quality
Automatically records on motion detection
Send alerts on motion detection
Reolink Argus 2 IP Security Camera
I have read countless reviews on various IP cameras, my decision was to go with the battery operated Reolink Argus 2 IP security camera. The Argus 2 is a 1080p full HD camera fitted with the new Sony Starlight 2MP cmos sensor that allows clearer night vision. The camera comes with a detachable 5200MaH rechargeable battery.
What I like about this camera is that there is NO NEED for subscriptions to view the live feed or recordings!
Features of the Argus 2 IP Camera
Full HD 1080P
100% wire free
Removable rechargeable battery
Starlight night vision Sony CMOS sensor
Smart P.I.R sensor
Two way audio
Wide 130 degree viewing angle
Motion recording to SD card
Live view anytime without the need for subscriptions
Motion sensing recording without the need for subscriptions
Option to enable alarm on motion detection
Reolink IP Camera No Subscription Required To Playback Recordings
As mentioned before, one of the deciding factors for me was to have a IP security camera where I did not have to pay any subscriptions to be able to view recordings. The Reolink App requires you to create an account to be able to login to your camera. Recordings are stored on an up to 64GB SD card and as an optional extra you can sign up to the Reolink cloud storage offering.
The Reolink App is user friendly and intuitive. If the PIR motion sensor push notification is enabled, you will get notifications directly to your phone notification area.
I especially like the attention that went in to the playback section. Recordings are kept on a timeline, and can be viewed easily by selecting a time and then using the play option. The user has the option to download videos or to take screenshots of scenes.
Reolink Argus 2 Full HD video quality
The Reolink Argus 2 is an easy to install and use battery operated IP security camera that comes in at a very competitive price and packs oodles of features.
I have had the Reolink Argus 2 for exactly a month. The battery as of writing this is sitting at 57%. Naturally, I have done a lot of testing so the battery could potentially go for two to three months in my use scenario.
I am very happy with the Argus 2 and it gets my recommendation.
A while back I had a client call me up complaining that their all-in-one computer was freezing on occasion. After some over the phone troubleshooting it was evident that the computer is overheating.
The next day the client dropped it off at my workshop. I proceed to install a hardware monitor which checked CPU usage and temperature, I noticed that the cpu was getting to to temps in excess of 100 degrees centigrade! Even the GPU was over 100 degrees centigrade.
The system fans and CPU/GPU fans were running at 100%, atleast that wasnt the problem… I moved on to taking the all-in-one pc apart.
Upon removing the covers I couldnt find any visual concerns, everything seemed fine. I started up the all-in-one without the covers and low and behold the CPU and GPU was smoking hot!
Cranck up the volume to hear my finger sizzle.
I then checked the CPU and GPU temperatures with my multimeter, smoking hot indeed!
Mmm the thermal paste must be old and dried up I thought. I took the heatpipe off the CPU and GPU and applied new artic silver thermal compound. Guess what? That didnt make a difference.
Heat Pipe Failure
A heat pipe is the copper tubing inbetween the CPU or GPU heatsink and the radiator/fan cooling unit. Heat pipes transfer heat away from the CPU/GPU to the radiator/cooling unit. Without the heat pipe working correctly the system cannot draw enough heat away from these devices and they overheat.
In this particular case the same was true, the heat pipe seems to only last a specific period, after that the gas/liquid leaks out. Or just magically dissapears.
My trusty HP Probook 4320s onboard graphics chipset packed up rendering it useless. Seeing I never had any issues prior to the GPU packing up, I decided to purchase a replacement HP Probook 450 G6. Within minutes of starting up the new Probook I noticed the laptop touchpad pointer would sometimes jump to the bottom left part of the screen when I tried using the left click function of the touchpad. Needless to say I was very disappointed that my brand new laptop had touchpad issues right out of the box!
Laptop Touchpad Cursor Jumping
After running through the initial Windows 10 setup process – which was very annoying caused the pointer kept jumping around. I recorded a video for HP support. Notice in the video how the pointer jumps to the Windows start button.
Troubleshoot Laptop Touchpad Issues
The very first thing I did was to try and re create the touchpad issue, I knew that if I was to contact HP support they would want me to show them the issue. The problem was that it occurred randomly, sometimes it would take around 6 minutes to appear and at other times it would happen within seconds. I could not find a way to re create the issue, it was random.
The next thing I did was to see if the problem persisted in the HP bios. I restarted the laptop and hit “esc” repeatedly at the HP start up screen then proceeded to the “BIOS” page. The touch pad seemed to work fine in the BIOS, The touch padpointer never glitched or jumped like it did in Windows. That rules out hardware issues.
I then proceeded to removing the hardware from device manager. I removed both the “HID compliant touch pad” and “Synaptics HID compliant touch pad device” Then restarted the computer. After the restart the device was re installed but the touchpad issue was still there.
Next step was to update the touchpad drivers. I used “HP Support Assistant” to check for driver updates. The application found various firmware and driver updates which I proceeded to install. Couple of reboots later and still have the same touchpad issue.
Many hours later I get tired of this and get on the line with HP support which takes me through the entire process again of firmware updates, driver updates, bios testing, safe mode testing etc.. I even had to make a video of what was happening. The final outcome was to reset the HP laptop Windows 10. This was a big pain cause I have already installed all my typical used applications and files.
40 mins later the process was complete and the Windows 10 initial setup process started, to my amazement the touchpad buttons were not working anymore. The touch pad cursor moved but both the left and right button function no longer worked, how annoying.
I got back to HP support reporting after the Windows 10 reset that the touchpad buttons were not working at all. I was advised to try another reset. Which I did and it did not fix the issue of the touchpad buttons not working. I now started to get blue screens about a “Synaptics” related file causing a memory fault. It was evident that this is a driver issue, what made it more confusing is that the latest HP touchpad driver made it worse.
Many, many hours of testing different drivers I got a driver that works – Did I mention there are no drivers on the Synaptic website! ?♂️
Back to the driver that does work. I found it on the MSI website and it is intended for an MSI based laptop but there seems to be no ill effects, it works and that’s that.
