Need Help understanding Mosfet IXTL2N450 .   It is a High Voltage N-Channel Mosfet with a low gate.

I am new to mosfets so please bear with me.  

I set up a basic circuit on a bread board to understand this Fet better.  

I am using 5v because it is easier to work with than my 2kv power supply I intend to use after understanding this fet better.

Problem:  When I apply 5v+ to the drain I am measuring 5v+ at the Source.  When I apply 5v+ to the gate it does nothing.... confused.  

Why is the drain 5v passing to the source without the gate voltage being applied?

Please school me. Thank you.

The yellow arrow points to a part that appears to be intended to be removed. I am unable to get it off. I guess this is where a AAA battery might be located.
The small arrow points to a rubber button of some sort for some unknown purpose.
Would this device require a battery?
We are in the process of deploying  new laptops, PCs and MACs   across the board to employees at all branches.
Would appreciate the advice of Experts before the handover:

1. Which is the best software to monitor in case the  laptop/PC/MAC gets lost and to get it back.
2. What the best way to physically secure these devices.

Any other advice will be appreciated.
I am looking to build a cheap storage device using a DELL perc H330 PCIE RAID adapter and a few HGST 6TB SAS disks.

I tried using a couple of older (6+ years) desktop motherboards but neither of them would allow the RAID controller as a boot device.

Can you please recommend something relatively cheap that's proven to work in this scenario? UK market preferrably, can be second hand.
Good afternoon experts, have a quandary i'm hoping someone can help me with.
Had a client unbox new hardware and add to Azure AD with their work email address. Before realizing it was in Azure AD, I had renamed the box, created a local admin account and removed his original admin account (name@company.com) and was preparing to add it to local AD. Attempted to add and had the error come up.

Logged into Azure portal and deleted it from listed devices and assumed after sync that I could then add to local AD but no such luck.

So tracked down original name of workstation when it was originally added to Azure by the user through the wizard and waited for the Azure sync to happen.
Attempted to add to local AD again but still receiving error...

Not sure how to rectify this at this point, any suggestions?

only thing I'm thinking at this point is to reset/re-image pc to factory default and start over & add to domain,

I have a Konica Minolta Magicolor 2400w. I just closed a question I answered myself on EE. I found the solution on youtube. 37k people watched the video so that tells me I am not alone. Here is the video that solved this problem from the question I asked. My EE Question

Basically what I had to do is take a solenoid and place a small felt pad (seen in video 2) in a spot that allows a space between a contact.  It got rid of the errors from the previous question. Unfortunately now I have the following problem that was not there previously and shows no relation to the previous problem. I new mysterious problem.  See image attached.

Video 1 - Showing How to place the felt pad on a specific solenoid.
Video 2 - Showing how to access the unit and solenoids to check for contact ability.

So all I did was put the felt pad on the lower Solenoid seen in video the blue one not the yellow one from video 1. I get duplication or bleed through from the toner on page 1 to 2 and 2 to 3. Also noticed an obvious big line on the first page only. Makes NO sense to me. Since I fixed the original problem I had and now hove a new one. Does anyone have any thoughts on a solution or what to try...? Also paper weight is 20 lbs paper.
New print problem.
I am looking for a USB thumb drive with an ink pen built-in to pass out as party gifts.

Assistance is greatly appreciated.
I have a Lenovo Yoga 3 Pro which I try to upgrade the memory from 8 GB to 16 GB. When I open this laptop I could not find any slots. I guess this is not upgradeable but I would like to confirm that with you.

Is there any other way I could make this laptop more faster?

I hope to hear from you soon.

Best regards,
Hello and Good Evening Everyone,

          This question is going to be a bit difficult to explain, so, I hope everyone will be patient with me.   That said, here it goes.  Basically, I have a 3 prong power outlet which works but mounted to the wall sideways.  However, I have a holiday decoration which will need to connect to an outlet that is up and down in order for it to be in its proper orientation.  Given this dilemma, I am wondering if there might be a power adapter which will have a male connector with 3 prongs which will fit into this sideways wall outlet, yet, have a 3 prong open connection on the other end which will be in an upright or up and down position so I can plug my holiday decoration into it in its proper position.  

            In closing, I am not even sure if such an adapter exists, but, I know if it does, you guys will be able to locate it.   In the meantime, I will look forward to reviewing whatever everyone can find out regarding this situation.  

            Thank you

Hello to everyone,

the motherboard of my main PC is broken. It was an old gigabyte GA-Z87-HD3. Can some one help me to find the same model in the UE,because I live in italy,or even outside,old or new,at a decent price and with decent shipping times ? I thought to get the same model of motherboard because in that PC I have again Windows 10 installed wth all the programs,settngs,and so on and I want to transfer everything to a new PC with the tool "laplink pc mover". But to make this,I need that the old PC was still alive. Let me know. thanks.
Hello, i have a SATA DVD recorder that i cant use on my mac mini because It miss a SATA port,since the only port is taken by the HD. I ve thought to buy a converter from SATA to USB that allpw me to burn dvds through the USB port. Can u suggest to me a good one ? Thanks.

Some time back I had experts help me with a bunch old DVD I wanted to put in the cloud.  Today I have a series of DVD that the computer just doesn't recognize as to "No DVD  in D: drive".  I have checked the DVD and seem somewhat dirty or grimy or scratch? (that is my appreciation) - when I place them in my hands they do seema bit scratched and some grime "maybe" in some places; I say grime because if I press it it smudges  somewhat (if u take a cloesup on certain areas u can see them).  So i would like to know if you guys can take a look at the image and recommend if there is a way to fix them or clean them or what can I do to be able to have my computer read them.

I have a problem  with an htmi port which is connected with an LG tv. I connect a pc via the htmi port  to lg tv for presentation (when the pc is present word/power point document) then everything is ok the problem appear when i try to present video to the pc. The tv is disconnected from pc.

Is anyone who have any suggestion how to fix this issue?

The battery on my Lenovo Ideapad 330S will not charge, despite the fact that it's plugged in.

The driver is up to date, so I cannot install a driver to eliminate this issue.

How do I get my laptop's battery to charge?


Dear Experts

I have a question related to controller M1015. I want to use it in IT mode for Unraid server.

In specification I can read this:
The ServeRAID M1015 SAS/SATA Controller has the following specifications:

Eight internal 6 Gbps SAS/SATA ports
Supports SAS and SATA drives (but not in the same RAID volume)
Two Mini-SAS internal connectors (SFF-8087)
6 Gbps throughput per port
LSI SAS2008 6 Gbps RAID on Chip (ROC) controller
x8 PCI Express 2.0 host interface
Supports RAID levels 0, 1, 10 (RAID levels 5 and 50 with optional ServeRAID M1000 Series Advanced Feature Key)
Connects to up to 16 SAS or SATA drives
Supports up to 16 logical volumes
Supports LUN sizes up to 64 TB
Configurable stripe size up to 64 KB
Compliant with Disk Data Format (DDF) configuration on disk (COD)
S.M.A.R.T. support

What I do not understand is - does this controller allows to connect 16 physical SATA drives? If yes why it reports only 8 internal ports?

many thanks for your advice

Power 'and' display.

I thought that I would be able to use a micro-usb to usb-c cable to pair this Magedok T1116D 1080P FHD Capacitive Touch Portable Monitor shown here http://magedok.com/touch-screen-monitor-t116c with this Microsoft Surface Go device https://www.microsoft.com/en-us/p/surface-go/8V9DP4LNKNSZ/L8M8?activetab=pivot%3aoverviewtab.

While the monitor does come on when it is plugged in using only the micro-usb to usb-c cable, it says "no signal" very briefly, and goes to black.

Is there any way to pair the devices so that the second screen will function?
I need to upgrade my PC from the motherboard up it's been several years since I last did this so I'm out off touch in terms of component computability and jargon

I've narrowed it down to 2 mobo's
Can someone tell me the difference


These 2 both have VGA & DVI ports and 6 SATA3 a piece which my main criteria

they both cost about the same so I'd like to know which is the better board?
and suggestions on what CPU / memory (2 x 8GB or 2 X 16GB depending on cost differance) to buy

Also overclockers Are doing the ASUS in  a Built to order bundle this is over £100 GBP more than buying the parts elsewhere separately
Not sure if this means put together and tested
New server for a site of approx. 30-35 users.  Will be running 4-VM's in Hyper-V on W2K19 Server OS (VM's- DC/Print Server, Remote Desktop Server (minimal use), 2-Application servers). Possible future File VM (would need more MS licensing).  Purchasing a new HPE DL380 Gen 10 Server as the Hyper-V Host.  2-processor (24-core), 128GB RAM, P816i-a SR Gen10 Controller with 16-open SFF slots.  Thinking OBR RAID 10, (8) 600GB SAS 10K 12Gb/s drives plus (2) hot spare.  Extra bays for future growth.  Will have 1-Array with 2-logical drives- one for Host OS and one for the VM's. I am researching SSD options from HPE as well but looking to justify cost to owners.  

Question- Should I be installing SSD in this configuration?  Read, Write or Mixed use?  Site typically runs servers 6-7+ years.  SATA or SAS SSD (leaning towards SAS SSD if we go SSD route). Trying to justify the extra cost of the SSD setup.  The SSD SAS 12GB/s option from HPE is pricey.

Thanks in advance for the input.
I have two sets of computer speakers with no a/c adapter though they require one. No manual.
I have a box of misc. adapters. Which ones should I avoid trying without ruining the speakers. Thanks.
I need a portable swivel arm that secures to the edge of a table for my Magedok T1116D 1080P FHD Capacitive Touch Portable Monitor shown here http://magedok.com/touch-screen-monitor-t116c. It does not have VESA holes on the back despite the picture that shows them.  The screen is 7.5" tall when turned to landscape view. That's the shortest distance edge-to-edge, so the arm needs to be able to hold that securely.

The two pieces that I purchased on Amazon are noted below, and while they are portable enough to put in a laptop bag, which I like a lot; they are not sturdy enough to hold the Magedok where it doesn't move around too easily.
1. https://www.amazon.com/gp/product/B07CTFZSXZ/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
2.  https://www.amazon.com/gp/product/B00W51I2L6/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

If I find something that works, the plan will be to get it fully assembled and leave it fully assembled so that I can just pull it out in a ready state, and attach it to the side of a table when I am ready to do a demo in a public place.

Assistance in finding the right monitor arm to give me this perfect balance between sturdy and compactness is greatly appreciated.
I have an earphone with a lightening port, I can use it with my iPhone.
However, I want to use it also on my other devices that only have a 3.5mm port.
Is there any adapter in the market for such purpose?
Hello and Good Evening Everyone,

         Yes, I am needing an online purchase link for a 6-foot HDMI cable which will be compatible an HDMI Switch 3 to 1 4K Ultra HD box.  It will be needed to interface the Output port of this box with the HDMI input of my VIZIO television set.  Just in case this information is needed, here is a link to the location of the purchased HDMI Switch https://www.amazon.com/GANA-Intelligent-Switcher-Splitter-Supports/dp/B0739GSKV2?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-d-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B0739GSKV2

          Thank you

Hello and Good Evening Everyone,

         I have an HDMI Switch 3 to 1 4K Ultra HD component which has stirred up some questions within my mind.  One of which is the IR port.  It is my understanding of the IR port that it is needed so the HDMI Switch 3 port amplifier selector remote control can transmit a signal needed to navigate between the HDMI channels, namely, HDMI 1, HDMI 2, and HDMI 3 respectively.  That said, I wonder how the receiver interfaces with the HDMI Switch box.  One of the accessories which came with the package is a black cable with one end having a connector on one end and an enclosed block on the other end.  Could this be the receiver for the remote which should interface with the HDMI Switch box?

          Any feedback which can be given in reply to this question will be greatly appreciated.

          Thank you

Hello and Good Evening Everyone,

         I am wondering if an HDMI Switch 3 to 1 4K Ultra HD requires an external power source.   The reason I ask is that the USB to power connector cable for the DC 5V port is not long enough to reach any of the charging USB ports of my power strip connected to the wall outlet.  

         Thank you
