Screen goes all blue when opened.

When I open my MBP I see my usual desktop picture for about 1 sec and then the screen goes to all monochromatic apple blue. This lasts about 3 secs. and then it goes back to my usual desktop pic? Just started happening for some reason. Any ideas?

No. I only use my MBP for personal use. I agree it does not seem like a serious problem yet but it seems like these problems metastisize sometimes.

Compaq Presario CQ40-327TU Notebook PC Display problem

Hi,
My product is Compaq Presario CQ40-327TU Notebook PC originally with Windows XP edition. Recently I installed Windows 7 in my laptop from USB pen drive. Installation went fine, but it does not ask for C drive format. I installed in the C drive where Windows XP installed previously . After installation of my laptop working fine. Some times the screen goes blank (black) and come back after few minutes and in notification area it shows "Display driver Intel Graphics Accelerator Drivers for Windows 7 (R) stopped responding and has successfully recovered." like that I am getting a notification. In my system information, I checked it shows Windows 7 in OS. It happens only when I toggle to different windows or applications. I checked display adapters in device manager and it shows "Mobile Intel(R) 45 Express Chipset Family (Microsoft Corporation - WDDM 1.1)" . When I tried to update display adapter it showed already uptodate. Can I expect some solution for my problem here. Also after OS installed I found Windows.old folder in C drive. Can I removed that folder?
Thanks in advance.
Regards,
Venugopal

Unable to boot Compaq Presario CQ40-340TU

Hi I have a Compaq Presario CQ40-340TU laptop. My problem is that I can't boot. I already change the harddisk since there are bad sector. Then when I connect my new hard disk, the laptop can not detect it, so i try connecting the new hardisk on my desktop, and installed Vista for the OS. When I return the new harddisk with installed Vista OS, I still can't boot the laptop.
I also try to boot the new hard disk in my desktop,it works fine. So i think there's some problem on my laptop?
Anybody know what seems to be the problem? Please help

check whether the HDD is dtected in the BIOS or not ! do that by tapping F10 while the NB boots...if the hdd is not detected then u need to get another hdd....if the hdd is detected then run the self test.....if no error comes then take the NB along with the HDD and ask for the compatibility at the store...

My Compaq presario CQ40 battery

Sir,
I got a Compaq presario CQ40 notebook. My battery displays ....plugged in, not charging....I guess reason is that my battery has dried up....so i would like to ask that is it a safe using that battery for few days .....or it has chances to explode.......its urgent . also i would like to know the price of replacement of new battery.
,Thank You
~Shubham

If your power adapter is rated for 90Watts, then my next thought would be to try a different 12 cell battery from a different manufacturer. Most (if not all...) newer batteries have a small chip inside that relays information back to the charging circuit in your laptop. This is what "tells" your laptop charging percentage of the battery, battery status and how much to charge it. Either the new battery has a defective chip, or it's missing... At least thats what it sounds like to me.
You should have some type of guarantee from the website if battery is DOA from the start.

Louis

Compaq Presario CQ40-106TU Strange noise

hi every HP products owners,
I’ve bought Compaq Presario CQ40-106TU notebook 3 weeks ago, till now, when I play music or movies, every 5~6 minutes I hear a short distorted noise thru earphone or speakers.
I have uninstalled and reinstalled sound driver. I have fully recovered my notebook, but this issue is still persisting.
When it is mute or I don’t play music or movie there is no noise. in case of all kind of music or movies, online, radio, playing by all kind of media player same as windows media player, jet Audio, winamp, i have this problem.
the notebook has a IDT High Definition Audio CODEC sound system. in sound card property it is mentioned that sound system works properly, but this problem really makes me mad.
The noise sometimes interrupts the music for an instant.
What can I do? Is it hardware problem?
I appreciate anykind of help or instructions.

Try pulling down the spill level and reducing the spill tint. You're probably going to have to tweak the color selection manually.

Compaq presario v6210US blank screen

I have a "compaq presario v6210US" which worked great for a while then it just shut itself off and restarted and the screen stayed black. Now it keeps restarting itself but the screen stays blakc. I can hear the fan and hard drive and everything else running the way it's supposed to. I heard that this has happened to a bunch of other people so it sounds like a defect to me. How do I get it fixed or do I just pull the hard drive, toss the Presario and get a competitors laptop?

Hello @Sachmo499 ,
Welcome to the HP Forums!
I understand your notebook keeps restarting and displays a black screen.
Here's a great place to start troubleshooting startup issues on a notebook:
Computer Does Not Start and the LEDs Blink or the Computer Beeps.
Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot.
Testing for Hardware Failures (Windows 7, Vista) or Testing for Hardware Failures (Windows 8).
If you search for any notebook boot issues or black screen, regardless of the brand you will find this issue everywhere. There are currently no recalls for this product.
If you wish to have the notebook repaired I would suggest calling HP Phone Support for service/repair options. You can contact HP Technical Support at 1-800-474-6836 in North America. For all other regions click here.
If you wish to remove the HDD and connect it to another computer to backup your info, you can follow this guide: Compaq Presario V6000 Notebook PC.
Hopefully this helps!

Compaq Presario CQ56-219WM keyboard frequently misses letters when I am typing

When I am typing on my Compaq Presario CQ56-219WM I frequently miss letters and spaces. I have a USB keyboard plugged in, but the missing letters happens on both the laptop's keyboard and the USB keyboard. I did not notice this issue happening before I installed a Plugable USB 2.0 Universal Laptop Docking Station. However, I am a bit baffled since this problem happens even when the docking station is not connected and I am just using the integrated notebook keyboard.
I use Windows 7 Home Premium.
Would someone be able to tell me what to do, if anything, to resolve this issue? It's really frustrating to have to constantly spell check to try and catch the errors!

Hi MrsJP. Try updating the BIOS in your notebook. Go to this link http://goo.gl/rk8CV and select which version of Windows 7 you are using and click next. It will display all downloads available for your notebook, including the BIOS update.
Here http://goo.gl/wTZr6 is a document that will hopefully answer any questions about finding and updating/installing your BIOS.
Please let me know if this fixes your issue or if you need anything else.

Background turns blue when opening new file or exiting file.

Hello,
I am working in Photoshop cs6 on a PC, Windows 7. I was working on my Wacom tablet and accidentally dropped my pen tool on the tablet. When I looked up, my background was blue. I'm not sure what happened, but I can't figure out how to change it back to white. It must have changed something, just don't know what. This happens if I open a "new page" or if I open an exiting file. I checked preferences, it all seems ok there.
Photoshop open normally as seen below. Second photo show what it looks like when opening a new screen or an existing file. Any help would be appreciated.
Thanks

There's a preference to change the color of the screen. I'm not at a computer right now that has PS, but you might want to try right clicking with the move tool and see is there is a menu option for changing the color. Or check the main preferences ctrl/cmd-k.
