Hi All,
I have an HP Pavilion HDX949nr Entertainment Notebook PC with 20.1 inch wide screen. The problem with my laptop is that when i power up the PC, i only hear the it booting and the LCD backlight comes on but there is no video. The screen is completely blank. I have tried using an external monitor but the result is the same(there is no video signal to the external monitor). Is it possible that the video graphics adapter is damaged? Please any help on this will be greatly appreciated. Thank you.

Anything is possible at this point... can you see the BIOS images at all? If so, try to boot with a bootable CD like some sort of Linux, if that works, you have a driver problem. If not, then you definitely have some sort of hardware problem. On laptops, I've also seen the video cable get damaged from wear n tear (since they're so thin). Do you have integrated graphics or a video card? If you have a video card, then you can just buy a cheap replacement to see if you get graphics by replacing it, if you have integrated graphics, then you have to get the laptop serviced by the manufacturer, although depending on the age of the laptop, may just be worth buying something new.
It's easy to rescue your files, post questions if you need help with that.

I reckon your laptop is hosed.
400 notes? Get a new one and save yourself the time.

Less than a year ago I bought an HP TouchSmart TM2-2050 for use at work. I LOVED IT. It was a convertible tablet that had a Core i3 processor, a decent size screen, capacitive multi-touch screen with stylus, etc. and it cost less than $1000. It was a bit heavy but I was able to live with that.
I left that job and wanted to buy a new one. HP has since dropped their tablet line and I have been unable to find anything that compares. 
ASUS has their Eee line with resistive touchscreens and Atom processor. My wife has one, and the CPU can't keep up with the stylus.
Everyone has a bloody Android tablet  which I might be able to live with if they had a stylus and could run BSD.
Dell and a few others have sub-$1000 tablets, but all with Atom processors.
There are still some "real" tablets out there (Dell, Lenovo, Fujitsu, etc) if you're willing to spend $1000-5000. I'm not.
I know that world is all gaga over touch these days, but I loved being able to take notes, add a drawing to chart on virtual paper.
Is the stylus dead?
Will Windows 8 make the problem better or worse?

Having recently purchased a new HP Deskjet 3070 network printer, I have noticed a small but very annoying issue.
Every 30 seconds or so, the 'Thinking' icon appears and further investigation shows it to be HPNetworkCommunicator.exe polling.
I cannot stop the process, it appears and disappears from the list and short of uninstalling the printer is there any remedy?

Have you looked to see if it's a windows service? If so, just stop the service from starting automatically, change the setting to manual. If it's not a service, there may be some other service starting up the executable indirectly, so it could take a bit of investigating to find the culprit.
Other places where it may be getting started from:
- Set up as a "startup" application?
- Windows task (look at task scheduler)?
...but it's most likely somehow associated with a service.

Thanks Albert, I will check this out when I get home.

If I remember correctly, last I installed an HP printer, they don't give you an option to turn off their annoying software, but at least they do name their services/apps HP something or another, so they should be easy to spot.
Forgot to mention one other place to look, in Windows, all startup applications and services can be chosen (selective startup) by typing msconfig in a command prompt.

So it is a dedicated printer, dedicated to your machine. So guess what networkupdate,exe is doing and decide if you need it or not.
Tip:
Find it ijn the registry. Rename it to networkupdate.bak.
Restart the machine. If you can print, then yippedee doo dah. Leave it as is. If not, rename it back to .exe and put up with the popup thingy.

Delete its registry entry. That will stop it running.

You asked Dave, no need to vote me a one for it.

Hi!
I am currently learning how to write drivers and in an example the code was supposed to raise the IRQL of all CPUs to DISPATCH_LEVEL but I keep getting BSOD with the error IRQL_NOT_LESS_OR_EQUAL
Out of curiosity, I tried changing the level of IRQL and if I changed it to APC_LEVEL, I still get a BSOD but I no longer see the IRQL_NOT_LESS_OR_EQUAL message.
The code below is not complete, I just posted some parts of the code which I think might be responsible for the BSOD.
KIRQL ChangeIRQL()
{
if (currentirql < DISPATCH_LEVEL)
{
KeRaiseIrql(DISPATCH_LEVEL, &previousirql);
}
return (previousirql);
}
PKDPC LockCPU()
{
if(KeGetCurrentIrql() != DISPATCH_LEVEL)
{
return NULL;
}
}
NTSTATUS DriverEntry(IN PDRIVER_OBJECT ptrDriverObject, IN PUNICODE_STRING registryPath)
{
irql = ChangeIRQL();
dpcPtr = LockCPU();
}

If you get the classic IRQL_NOT_LESS_OR_EQUAL you are touching pagable code or data at elevated IRTQL.
Dont. This is either an immediate BSOD, or instability (just because a page is pageable doesnt mean it has been) so use verifier to check your driver at all times.
--edit--
Typical. Almost noone knows what the hell kernel programmers are talking about; no response, no answer, no 'uh? what are you on about?'. Nothing. Makes me wonder why anyone posts about kernel stuff here.
Mind you, the google kernel forums have died, OSR isnt picking up the volume.
Hey ho. I guess I live in an isolated world.

Driverentry code is normally pageable, so raising IRQL to dispatch might be against the rules.
Anyway, any feedback? Or am I just pissing in the wind?

Thanks for the reply, Eric. Will include checks before attempting to raise the IRQL

Hi,
Anyone tried to use Windows Server 2008 as domain control and Linux as proxy server to administrate and maintain the internet usage?
can any explain how it can be done please..
Thanks,

Linux Server running Squid Proxy and using GPO on the Domain Controller to set the Proxy Server for all Domain Member Computers to use the Linux Server as the proxy server.
Don't know the settings without being in fromt of a box and not sure in Squid has been superceded.

Hi,
I have an existing Windows Server 2008 and I want to install Linux Server on it (Debian) to have both up and running the same time.
The Windows Server 2008 will be my domain controller while the Debian will be my Mail Server.
can any one guide on what's the best practice to do this?
Thanks,
Jassim

There only way you're going to do that is if you install each in a virtual machine, using something like HyperV or VMWare ESX. There is no other way to have two operating systems running on the same machine at the same time.
