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

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.

Sound Problem in Compaq Presario CQ40-108TU

I've Transcend 2GB DDR2 667 memory and put it in my laptop (Compaq Presario CQ40-108tu). It read the whole 4GB memory coz I'm using Windows Vista Ultimate 64-bit but it doesn't have an audio.

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...

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.

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

Failure in Flashing the BIOS of Compaq Presario CQ40-109TU

Good day to all.
I am upgrading my Compaq laptop from its default Windows Vista Home Basic to Windows 7 Ultimate 32-Bit. My laptop model is CQ40-109TU.
I freshly install the Windows 7 and download all the recommended drivers and softwares from HP/Compaq site for my laptop model with Windows 7 32-Bit.
After finishing the installation of Windows 7, Avira Antivirus and Windows Updates, my laptop starts up successfully. But after I install the recommended BIOS version F.55 A (sp45765.exe), my laptop hangs at start up when Compaq logo is displayed, and it does not respond in any keys I press (like Esc, F8, F12, etc.) to view the BIOS configuration. It only beeps after pressing a key several times.
Also, I notice that my laptop does not charging too after the laptop restart. The LED on AC adapter has light, but the light where the adapter connects to my laptop is off. But there is a blinking light in the thunder icon while the charger is connected to my laptop. So, the charger is okay and supplies electricity to my laptop. But why the light, that indicates the laptop is charging, is off? Currently, the battery is drained already.
My laptop's previous and working version of BIOS is F.12, and I have no backup for that.
I run the BIOS setup (sp45765.exe) just by clicking the file in Windows-mode not in DOS-mode, just what was said in the directions. I think, power interruption is not the cause of the problem because the charger or AC adapter is properly connected and the battery is fully charged during the upgrade.
What happen to my laptop? Do I miss something during my installation process, or the BIOS version F.55 A does not really compatible to my laptop? Is there any workaround for this problem? How can I restore my previous BIOS version F.12?
I am very hopeless, and I don't know what to do. Please help me.

Restoring F.12 might be a good move.The guys at My Digital Life have tested a procedure using usb flash disk:

Compaq presario cq50-215nr Battery melted

I have a compaq that was runnig great then the battery section on windows vista had a red slash tru it.
I pulled the battery out and it has a burned in hole in it.
I think the battery shorted out
Any body else had this problem ?
Thanks I am a disabled vet and unable to afford a new battery

I don't know what your budget is so I shopped batteries for the CQ50 on amazon.
I found a genuine HP battery for about $50 shipped a good deal, its $130 on the HP site
There are plenty of real cheap knock off brands for under $20, but who knows what the quality is or if they will last very long before they die or catch fire.

Compaq Presario CQ40-406AU Keyboad Replacement Issue!

I have the service manual for CQ40 but its definetely not the exactly same model because lots of things are different between the manual and my laptop. I have unscrewed and removed everything at the bottom ( besides WLAN and RAM modules ) but the keyboard/keyboard cover won't come off. I tried lifting the keyboard upwards alone and it didn't help, then I went to remove the cover and it won't move either. I tried lifting it with hand, moving it in forward direction to try to get it to disattach from any locks and nothing helps.
Any ideas how to remove the keyboard/keyboard cover from this laptop? Could really use some help right now!

If you know complete model/product number of your Compaq laptop, you can find list of available parts including complete chassis info over here
This list is also available in Service manual found over here
