I have a Dell OptiPlex 7050 - Core i7 7700 3.6 GHz - 8 GB - 1 TB, with 2 Display Ports, and an HDMI output port as well.
(There are no VGA ports available)
When connecting the HDMI monitor to the computer for the first time and powering it on, nothing appears on the display..
The monitor has power, is plugged into the HDMI port at the back of the computer, yet no output on the screen from the computer.. just a floating message from the monitor itself.. which proves that it's working...   (The monitor only has 2 HDMI inputs and nothing else to connect to the computer).

Can anyone assist with any suggestions?
Many thanks.

Currently, I'm confused about buying a new memory that's compatible with my current one.

I got:
G.skill Ripjaws 4 8GB (1 x 8GB) DDR4 2400MHz Desktop RAM (F4-2400C15S-8GRR)

The one I want:
Kingston Technology HyperX FURY Black 8 GB CL15 DIMM DDR4 2400 MT/s Internal Memory (HX424C15FB2/8)

Will those 2 memory sticks work together without any compatibility issues?

I've been given a used Lenovo T450 port replicator.

What is the exact model number of this port replicator?

I need to be sure that I download the right port replicator firmware update from the https://support.lenovo.com/us/en/solutions/pd014572 website.

The Docks on this website are identified by part numbers such as 40A40090WW.

I can identify the 40A2 on this Ultra Dock but I'm not sure what the full model number of this dock is. Also when I type in the FRU P/N number or the P/N number on the http://support.lenovo.com website I am told that no products match this query.

Based upon the picture of the sticker at the bottom of my dock what is the full part number of the dock?

Or what firmware update for this dock should I install?

Does anyone know of a company that would build a custom computer and ship it.

DELL & HP can't customize to the needs.

it's a very specific computer.
How many different monitors can be connected at one time to this Lenovo T450 docking station?

This docking station has the following monitor outputs on it:

- 1x HDMI 1.4*

- 1x VGA*

How many unique video displays can be provided if a monitor is connected to each one of these video outputs?

How can I determine if a Lenovo T450 laptop is quad core?

Here is a screenshot with my laptop specs.

I have lost access to the Distributor and Subscriber servers, and need to delete the publication.
I managed to delete the (pull) subscription database, locally only, so the subscription still shows as orphaned, on the publisher server.

I am trying to simply delete all replication related components.

I am trying to remove the publication, but I get an error that it cannot be removed due to a connected subscription.

I then try to remove the subscription, usign the script below - but I get a message that the subscription does not exist?

Can anyone help with why?

(Remove Subscription Command)

--Select your publication database



DECLARE @publication AS sysname;

DECLARE @subscriber AS sysname;

--enter your publication name

SET @publication = N'NxPub';

--enter subscriber name

SET @subscriber = N'NxSub';


EXEC sp_dropsubscription

@publication = @publication,

@article = N'all',

@subscriber = @subscriber


i know the usb 3 drive docks
my question is : is there anything faster on the market?  
 or is sata speed comparable to USB 3
in my betting software project i have 2 tables and a query like this:

procedure TMain.Button16Click(Sender: TObject);

ADOQuery8.SQL.Add ('SELECT SUM(W1) as total1, SUM(B1) as total2, COUNT(*) AS TOT');
ADOQuery8.SQL.Add ('FROM Table1');
ADOQuery8.SQL.Add ('WHERE League = '+QUOTEDSTR(adotable2.FieldByName('League').asstring));

It works very well, but i need to get only the first 30 records from table1 and not the whole records.
The table also has a date field called 'data', i made many tests but with no success...
It is a delphi app (embarcadero xe8) with ado components and ms access tables.


I have tried multiple times now and I am at a loss.  The customer has HP G6-1d01dx that has Windows 10 AU on it.  We are attempting to upgrade it to CU.  Every time that it goes through, it fails at 40%.  I keep getting the following error;

"Windows could not configure one or more system components. To install windows, restart the computer and then restart the installation."

This is using the upgrade tool.  I have also attempted to upgrade using a bootable USB but it failed with the picture included.
I have a new UPS 950VA BX950U-GR, just unboxed and plugged to line.
It's correct that no lights are on? If I turn on the ups I see green light flashing

I work at a small catholic school.  We have Epson projectors in our classrooms.  In some rooms we have large screen tvs.  We use PCs, MacBooks, and two different versions of iPads for students/staff.  They vary in age.  We have found that there is no single way to connect to the projector that works for each device.  I am looking for a solution (wireless utility or multiple connectors...iPad (small connector or 30-pin)-to-VGA/HDMI/USB, PC-to-VGA/HDMI/USB) that we could put in each classroom so that little to no instruction time is lost trying to connect student/staff devices to the projector.  Needless to say, finances are a concern.

We are looking at AirServer but does that need to be installed on each device or can it be installed on a single device in the room that would work?  Would a TeamViewer solution work?

Any suggestions would be much appreciated!

In a nut shell, plan to have a TSpeedButton,  by the same name on ten forms.
Whenever the button is clicked on any form, want to change the image and caption,
on all forms.
Something like this;

procedure TForm1.Button1Click(Sender: TObject);
  i, f: integer;
  s: string;


  with Application do begin

    for i := 0 to ComponentCount -1 do begin

      if Components[i].ClassName = 'TForm' then begin // or Application.Components[i].ClassType = TForm

        for f := 0 to Formx.ComponentCount -1 do begin

          if Formx.Components[i].ClassName = 'TSpeedButton' then begin

            if TSpeedButton.Name = 'SomethingSpecial' then

              Call another procedure with form and button info
              Set to caption and image

I am trying to operate 2 devices from a Solar/12V battery combination at a location where there is not electricity.   Almost more importantly, I'm trying to understand HOW to calculate the power a device will use every hour.   I'd like answers to questions below.. so I can get this stuff ordered... but if someone also could point me towards a resource that explains the calculation thing where a simple minded fellow as myself could understand it, that would be greatly appreciated.

Item 1 is an IP camera, Power is listed as 12V DC, 4W (I'm arriving at 4W by averaging IR use & non-IR use over a 24hour period, Camera specs say consumption is 2W normal, 6W when the infrared is on)

Item 2 is a Point to Point Antenna, Input Power is listed as 24V, .5A.

I have purchased a gadget that converts 12V to 24V (Input -12v - 13.8v, Output - 24V,2500mA)

PDF Drawing attached, sorry for the crude images, figured if I tried to make it look legit, I'd be laughed off the website.  :o)

My questions are this.
1. I think I understand that if I get a 100W solar panel, and it runs at 80% efficiency for 7 hours a day, I can roughly say I will charge a 12V battery 560watts.   ((100 * .8) * 7)   Correct?
2. is it possible to determine how many watts the two items above will use each hour?
3. Can I come straight off the batter to power both items?  I can't see OUTPUT terminals on the charger controller (like I do with other models).   I haven't purchased this yet, maybe it'll be …
We have a  Dell C3765dnf network printer that has a problem with the network cables easily detaching.

We have tried several brand new network cables and none of these network cables stay attached (even if the tab on the network cable is pulled out).

Currently the network cabled attached to this network cable has had to be taped in.

What can be done to fix this issue so we can tightly attach a network cable that won't become detached?
