Hi,
problem with your resolution.
Restart your Laptop press F8 key select safe mode press enter to continue follow the screen instruction. Go to my computer properties in that remove the display driver than restart the Laptop.

Don't do anything it will open in normal mode and windows will install VGA driver automatically.

I connected a HP Compaq Monitor Q2159 to my Dell laptop. But the monitor does not copy that of my DELL laptop. How do I make a correct connection?


If it is connected with a standard VGA lead and you use win7, right click on the battery icon and use the mobility centre to switch the screen on.

How can i fix my hp 210-1041NR mini laptop black screen problem,


Time for a trial and error.
1.connect your laptop to a monitor or tv that has a VGA connection.Use a vga cable and connect it to your laptop then to your TV or monitor.If the screen shows display and works on your TV or Monitor ,Then its likely that your Laptop screen is faulty which can be replaced.If it does NOT SHOW on your monitor or TV then it means your GPU is faulty which then you will need to replace the motherboard on your laptop.

No blinking cursor either?

{ If there is a blinking cursor, you would then use the Restoration Disk, IF you have it.
When asked choose Repair. (Non-Destructive Installation)
If you do not have it go to HP Support Worldwide, your country, and obtain the disk. (HP bought out Compaq. On the HP Support page for your country, go to the Top Right, click on the - Connect with HP - icon.

When you hover your mouse cursor over it, Connect with HP will briefly show)
The disk is free. The shipping and handling is not.
USA example: $17 for a 5 to 7 day ship, $24 for a 2 to 3 day ship. Call 1-800-474-6836. 24hrs a day, 7 days a week.

Have your Serial Number handy, to give to the nice representative on the phone. Bottom of the laptop in white Service Tag. S/N = Serial Number }

However no blinking cursor was stated. This means to me that it is a graphics problem.

The problem can be;
1) Graphics chipset
2) Video Cable. (Compaq/HP = Display Cable)

3) Screen Inverter. (IF used. Model Name and Model Number was not stated. This is the Product Number. P/N in white Service Tag, on bottom of laptop.

GENERALLY, if a CCFL is used for a Backlight, a screen Inverter is used. (Cold Cathode Fluorescent Lamp)

IF LED backlighting is used, GENERALLY NO screen Inverter is used. (Light Emitting Diode)
Does depend on what model we are talking about here.
There are some models that have used a screen Inverter, along with LED Backlighting.

4) LCD screen

A) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA connector, on the laptop.
Usually on one of the sides, or back.
Here is a general example of a VGA connector (port), and a VGA Cable,

http://en.wikipedia.org/wiki/VGA_Connector

Scroll down a little for VGA Cable example.

You can use a CRT type of monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable. (You can also use a VGA to DVI adapter, if the laptop has a DVI port on it,

http://en.wikipedia.org/wiki/Digital_Visual_Interface

You can click on any photo to enlarge. Sometimes you can enlarge twice )

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.
IF not;

You have at least 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Hold the Fn key down, and at the SAME time tap once on the F4 key. The F4 key is the Display Toggle-Over key.

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

NO display on external VGA monitor, means a problem with the graphics chipset.
Most of the time it is the MOUNTING of the graphics chipset TO motherboard.

The solder connections is the problem. Graphics chipset is reflowed to the motherboard, using an SMD/BGA Rework Station. Specialized shops have them.

Otherwise it means replacing the motherboard.

Good graphics on external VGA monitor means the problem is;
1) Video Cable
2) Screen Inverter (IF USED)
3) LCD screen

A Video Cable cost ranges from $9 to $22, with $9 being the norm.
It also just may have a loose connection. Loose at the motherboard side, or LCD screen side. May be screen Inverter cable connection, from Video Cable; is also loose.

So, you are looking at perhaps a loose connection of Video Cable.
Or a damaged Video Cable. (Replace then)

Problem may be the screen Inverter. (IF used)
They range from $9 to $22 also. (Again, $9 being the norm, or less)

LCD screen ranges from $60 to $245.
Just depends on what Compaq laptop it is.

Point?
Better to diagnose.
May find loose Video Cable connection, or bad Video Cable.
May find bad screen Inverter, if Video Cable is not the problem.

Some people jump the diagnostic flowchart, wind up spending $60 to $245 for an LCD screen, ONLY to find the problem was a $9 Video Cable, or FREE if the connection was loose.

Wish I could guide you from here. I step by step guide people, and this means replacing a motherboard in a laptop, if needed.
I have over 10,000 solutions, and many of them are for laptop repair. According to feedback from the asker's of the problems, I seem to have a very high ratio of accomplishment at this, because they repaired their problem/s.
(Brag, brag, lol!)

However it would seem a recent site development change, has rendered replies back from the problem asker, USELESS.
Haven't had a reply in two weeks, or more.
(Neither have the Top Experts)

When i turn on laptop screen goes all black no display


A) Shining a flashlight at the screen at various angles, do you see faint images?
No? Go on.

B) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port on the laptop.

Compaq Presario v3000? Left side towards the rear.
This is an example of a VGA connector (port), and VGA Cable,

http://en.wikipedia.org/wiki/VGA_Connector

Scroll down a little for VGA cable example. Note color of connectors does Not matter.

You can use a CRT type of monitor (Looks like a small TV ), or a flat LCD screen monitor if it has a VGA cable.

http://www.wisegeek.org/what-is-a-crt-monitor.htm

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.

IF not;
There are at least 3 display options;
1) Internal display of laptop monitor ONLY.
2) Internal display of laptop monitor AND external VGA monitor.
3) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the SAME time tap once on the F4 key.
The F4 key is the Display Toggle-Over key.

Still no display on external VGA monitor? (It takes a second)
Hold the Fn key down again, and tap once more on the F4 key.

NO display on the external VGA monitor, suggests a problem with the graphics chipset.
Most of the time it is the Mounting, of the graphics chipset TO motherboard.

The graphics chipset is mounted to the motherboard, with a BGA surface mount.

"HP Pavilion DV6000 Blank screen fix BGA rework video problem
This BGA rework fix also works on the HP DV2000, DV6000 and DV9000 there are a couple more HP's with this BGA video issue.
This is a design flaw that we solved with our upgraded copper heat sink and thermal compound.
Also effected by this issue are a couple Compaq models. The Comaq Presario V3000 V6000 and a couple of the Pavilion models."

Not showing for advertising of repair. Showing for adding extra copper sheeting material, to the graphics chipset.
A BGA Rework Station is the best method.

The problem, is inadequate cooling for the graphics chipset.
Bad design by HP.

As you can see in the above information, the bottom of the graphics chipset has Solder Balls.
These Solder Balls match up with Copper Pads on the motherboard.
(The Copper Pads are also gold plated)

The graphics chipset is set into place on the motherboard, with the Solder Balls lining up on the Copper Pads.
Heat is then applied at a specific temperature, and length of time.

This action melts the Solder Balls, and solders the graphics chipset TO the Copper Pads.
Which in turn of course, solders the graphics chipset TO the motherboard.

The solder connections made are called Solder Joints.
When the graphics chipset repeatedly overheats, the solder connections partially melt again.
Then the laptop is turned off, and the graphics chipset cools down.

This causes Cold Solder Joints, and a bad contact of graphics chipset TO motherboard.

If this is a problem with your laptop state back in a Comment.
Going on............

IF, the display shows on the external VGA monitor, and is good; the problem is the Video Cable, or inside the Display Assembly.
(screen Inverter or LCD screen)

Let me know after your diagnosis what the outcome is.
1) NO display on external VGA monitor.
2) Display on external VGA monitor.

Post back in a Comment.

HP pavillion dv9000 has black horizontal lines across screen and looks like a snowy background


Sounds like the screen is going bad. Isolate the problem by plugging an external monitor to the laptop. Borrow a monitor from a neighbor, friend, relative or co-worker to plug to the laptop. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If the Borrowed monitor does not show the black lines and snowy background, that proves your video card is ok and the problem is your lcd screen. If the borrowed monitor shows the same black lines ans snowy background it means your video card inside the computer has the issue.

The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

My HP Compaq 6730b screen isn't coming on. All the


Does it seem like the laptop booted up all the way except the screen is black? If so try the steps below:

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

It's not possible to connect your Monitor to the Laptop as the Pre Installed LCD Pannel of the Laptop reserves the Resources for Display Unit.
