The first post of a "TERMANAL" since 1980s
what in the word are you doing?
its a dump terminal, (means no computer real inside)
is there a computer involved? here? do tell what.
if i google IT, i get 1981.
really? an RS232c ASCII Terminal (yes used many and repaired many in the dark ages of puters)

why in the world fool with this old thing,
it needs to be connected to a computer made from the 1950s to 1980s.
surely you have no such Computer.
worse yet why fix it.?
tell why/?
all these are museum pieces now, all are.
there are web sites with relic schematics,
HP has none, after all , the people that used it are retired now..
like me...

here is a hint of the screen CRT works
make a RS232 loop black plug
so you can type and see your echo.
works all dumbb(sic) terminals
to make it work with real computers takes setting the BAUD rate
stop bits and 7/8 bit mode. and more if it needs modem lines set right.

SOURCE: Where is port to connect USB cable?

I'm sorry you're having trouble with this. I have put together a picture that shows where the mini-USB plug is supposed to be attached to the camera. I hope it helps. This picture actually shows plugging the AV cable into the receptical, but right behind it is the mini-USB port. This is where you connect the USB cable. It looks like you have to lift the flap on the corner to reveal the plugs.

SOURCE: Howto add a network printer on Wyse winterm S30 terminal?

The S30 terminal has the CE 5.0 operating system loaded as default. So you are limited by the operating system and not the hardware when it comes to network printing.

Here is a extract of the release notes for Windows CE 5.0:

"In Windows CE, TCP/IP supports network printing through the Server Message Block (SMB) protocol. It does not provide the Windows Line Printer Remote (LPR) Spooler. However, independent software vendors (ISVs) and original equipment manufacturers (OEMs) can add this support."

In short, you need a 3rd party software program or a (SMB) printer server setup to setup network printing on the S30 terminal..

Wyse also have add-on software to help, if you have CE 5.0 loaded then try the "Thinprint" add-on supplied as a free download by them.
Download Link:

I haven't tried this, so let me know if it works.

If I understand your post correctly....You state that you are hooking up a 240v heater and towards the end you speak of removing jumpers...W2 terminals..ect. It sounds to me your trying to us a 24v low voltage thermostat instead of a Line voltage thermostat.That's what I'd take a look at.

SOURCE: what terminal on the capacitor gets the blue wire from the run terminal on the compressor? Does it go in the terminal with the white wire or the blue wire?

Follow the start wire from the compressor to the capacitor, the run wire will go to the opposite side.
For instance if the white wire is the start wire on your compressor then the run wire will go to blue wire and vice versa.

How do i screenshot on my hp x2 detachable 10-p038TU laptop

Hiya Sarah
If its just a screenshot of your windows desktop just press the PrntScn button on the keyboard.
You can then paste it into whatever graphics app you want.

The PrtScn key is a standard feature of the Windows operating system.
  • When you press it, an image of your screen is copied to the Clipboard in your computer's memory.
  • Paste the screen capture into a document or image editing program to save and distribute it.

I cannot project to second screen

1) Laptop OFF, external display OFF, connect the external display to the laptop.

Turn the external display on.
Turn the laptop on.

There are at least THREE -> display options available.

1) Internal monitor of laptop ONLY'
2) Internal monitor of laptop and external display
3) External display ONLY

Hold the Fn key down, and tap on the F4 key once.
Still no?
Hold the Fn key down again, and tap once more on the F4 key.

No internal monitor, and not external display also, means problems with the graphics chipset. May be one of the HP/Compaq models, that has problems with the graphics chipset overheating.

Due to a poor cooling design for the graphics chipset.
Graphics chipset repeatedly overheats, and softens the solder connections of the graphics chipset to motherboard.
(BGA surface mount)

Laptop is turned off, and cools down. Solder connections (Solder joints), re-solidify. This causes Cold solder joints.

Remedy in this case is to reflow the graphics chipset, and add more cooling surface, to the small metal plate attached to the Cooling Tube, that sits on the graphics chipset.

There are two Fan/Heatsink Assemblies offered. (Thermal Module)

1) One is for models that have UMA motherboards.

[ Unified Memory Architecture.
A fancy way of stating the graphics memory is part of the System Resources. The Processor and Ram Memory.
Two other terms used are Integrated Graphics, or OnBoard Graphics.
ON the motherBOARD ]

HP 430463-001 part number,


It's also used for the HP Pavilion dv2000 series, which DOES have a problem with graphics chipset cooling.

Look at the photo of the HP 430463-001, and at the Black round Fan Assembly.
Look to the left at the copper Cooling Tube. See that triangle shaped area that sticks out? This tiny surface area is what cools the graphics chipset.

SERIOUSLY inadequate!

(The Processor sits under that black square at the top, that has a smaller square hole in it. Four screws surround it.
{ You are looking at a Top View of the Thermal Module )

2) The second Thermal Module offered is for motherboards that has discrete graphics.
HP 417081-001,

This time a Bottom view is shown.
Do you see a difference shari_n?
No? Neither do I!

Here is one tech's solution for this. This is for reference ONLY.
Not advertising for tech, nor website,

This gives you more information on the BGA surface mount, using a BGA Rework Station,

Do not know where video card is located

You have integrated or On-Board graphics which means your graphics controller is located on the mother board itself. fortunately you have a PCI-e expansion slot so you can buy a PCI-e graphics card to replace the on board graphics that is if your having graphics problems. or not if your just wanting to know where your graphics card or controller is located. Hope this helps

HP (Altec Lansing) monitor is displaying sideways, my friend lent me her laptop

Some graphics cards have rotation "hot keys" enabled by default and this is probably the most common cause of this problem. The exact procedure for rectifying the display may depend on the particular brand and configuration of the graphics card in the problem computer. One of the following options may help resolve the issue.

Option One:
Try using the keyboard combination, "Control + Alt + Up Arrow Key". Control + Alt along with one of the arrow keys is a fairly common rotation hot-key configuration and may just do the trick.

Option Two:
If Option One doesn't work, see if there is a graphics card icon displayed in the Notification Area (near the Windows Clock). Clicking (or right-clicking) the icon may reveal a "Rotation Settings" option that will allow you to revert to "normal" display.

Option Three:
If neither of the previous options help, try the following procedure.
  1. Right-click an open area of the desktop and click "Properties" to open the "Display Properties" window.

  2. Click the "Settings" tab and then click the "Advanced" button to open the monitor settings window.

  3. Click the tab corresponding to your graphics card. You may need to click one or more buttons within the tab to reveal a rotation settings option. Exactly where rotation settings are located will depend on the brand of graphics card installed.

  4. Once you locate the rotation settings, choose the "0 degrees" or "normal" option to change the display to upright. The rotations settings may also give you the option of disabling rotation hot keys so that the problem does not happen again.

  5. Click "OK" to save changes and exit out of any open properties windows

Display adapter corrupted nvidia geforce 7600 GT updates don't help at boot up display screen faded colour with many colums of !!!!, etc. and will only boot to welcome screen in safe mode then restart...

a 12 year old PC !!!
powers on, yes
all fans work, not stated and is 1st ,overheated is bad.
PSU fan, CPU fan and if present GPU fan all working perfectly
and heat sinks not packed lint as ALL DO 12 years old and never serviced. timely.

NO OS stated, you posted an old m7650n , PC. desktop
then fail to say its XP the dead OS and virus magnet?
no screen stated, is the screen old to, Monitor with old Dead
or near dead CCFL tubes (blackground)
what we do on all relics this old
1: test the monitor on a good PC?
2; test the PC on know good Monitor.?
easy no/?? simple tests, 1/2 the problem solved.

all that above from word "FADES" (wish could see it and watch)
lets say (i toss a coin) that the monitor is good.
PC bad.
PC needs a good power supply next.
what VGA jack are you using ,most desktop ,or many
have 2 jacks, one is main, board video
other is add-in board PCI card video, which one are you using
i cant see it.
ever see the PC run ok for a week? or just found this at garage sale. for $5?
matters big time as others tend to mess up parts inside guessing.
One error is not using the upgraded video card power aux jack
for 2 reasons, dont understand it, or forgot or the PSU doesnt
have that extra ATX2 wired power cable, rendering the aux vga card useless...... see how easy it is to mess up video.just that.

is the MOBO RTC coin cell good, over 2.9vdc with a meter?
if not get rid if that first. never seen one this old good , me.

then get the BIOS screens working first, forget the OS. for now.
then we can work that.. BIOS screens HOLD good.
no fade in BIOS??????

still has PS/2 keyboard, if yes, HP keyboard? still?
try another keyboard, in cases keys are stuck? !!!!!!!!!!!!!!!

if the screen does not fade in bios, then say that ,
as that is a whole other set of problems and causes.

facts: HP Pavilion Media Center TV m7650n Desktop PC this PC does have onboard mobo integrated graphic. runs the
as seen here

that GPU there is.
Integrated graphics using nVidia GeForce 6150SE

the page states

*Integrated video is not available if a graphics card is installed.
  • Integrated graphics using nVidia GeForce 6150SE
  • Up to 256MB (with 512MB or more PC memory)
  • Also supports PCI Express x16 graphics cards*
that 2nd bullet means main ram must be good. try swapping ram
if 2 DDR sticks try each one at a time, in bank 0?

if using express video now is the time to say. thanks.

Disable video graphics onPTGd1-LA

Every motherboard manufacturer has different ways of implementing the setting up of the display priority of the slots. If you add a PCI-E or AGP VGA card on a based board, there's no problem for the board to see your add-on card as the first display. If you add a PCI-E VGA card or a AGP/Super AGP VGA motherboard board, you will need to set up the display priority. Every board manufacturer has its own system of setting the priority up. Some of them will implement it in the BIOS, in the item "Integrated Peripheral"," Initial Display First", you can choose "PCI-E or AGP slot". However some other manufacturers implement the settings by using jumpers, if this is the case in your situation you will need to refer to your manual or contact the manufacturer for further help. The best solution is to seek help from the manufacturer of your board. Hope this might very helpful to you and good luck!
