Wireless and batter problems with Compaq Presario CQ45-315TX Notebook PC

Was using my Compaq a year or so when it suddenly stopped detecting the battery. Short time after it stopped detecting the wireless module (listed as error 702 during startup).
I've already made sure all of my drivers are up-to-date, automaticaly and manually. I read in other forums that a BIOS update would fix both of these problems. I downloaded the reccomended update to go from BIOS Version F.66 to F.66A. I'm not sure if it actually worked as the update was to the same versio and ID as the existing BIOS.
Is there another update for BIOS F.66 as the ones I've tried don't seem tio change its version after they run, or is there another solution to this problem?

Hi,
Try the following.
Download the Conexant HD Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp45001-45500/sp45166.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the Conexant device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery and plug in the AC Adapter.
Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Let Windows fully load - it will automatically load an audio driver, but just let this complete. Then open your Downloads folder, right click on the Conexant installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.

Problem with Compaq Presario V6000 laptop

Hi forum members! I am a newbie to this forum and i would like to introduce myself, my name is Hammy and I am from Glasgow. I have a problem with my laptop whih is a Compaq Presario V6000 running windows Vista, 32 bit product number V6254EA.
A few weeks ago when i turned on the computer it failed to boot up, the only thing visible on the screen is the bar at the bottom of the screen with `Microsoft Corporation` displayed below it.
I have tried starting it up in SAFE MODE but all that happens is that a certain amount of windows system drivers are loaded and then goes no further!
I have purchased recovery discs with no joy! I have also tried a hard reset which has not solved the problem. I tried the `hard drive self test, which after approx 30 seconds carrying out a quick test displayed the following message #1- 07 Fail.
If it is the hard drive or the motherboard that has failed is it possible to replace them.
Thanks

Did you burn the recovery disks? Will follow up with the manual and a link to buy the hdd.

Sound Problem with Compaq Presario

Hi,
I am using a Compaq Presario SR 1630IL desktop, Prod # EG224AA#ACJ, S/N INI54709VG. In my system Windows XP and Ubuntu 9.4 are installed with Ubuntu as the default OS. The PC is using Realtek ALC 880 sound card. The linux sound module is snd-hda-intel.
My problem is with the sound in linux. In windows the sound is very fine but in Ubuntu it is very less although my external amplifier is in full volume and the internal audio mixer too. I am using ALSA latest version for ubuntu.
I have tried all the howto's available in the webbut couldn't improve the situation. Is there any problem with ALC880 chipset in lunux.
Eagerly waiting for the assistanse from HP
Thanks

Problems with Compaq Presario CQ61

I have a Presario CQ61 and recently updated the iTunes software installed. Everything worked fine until I went to shut down the computer. While waiting for the windows menu to load it crashed, since then it hasn't worked (some 5 days).
When I turn it on it asks if I want to restart in normal windows mode of safe mode (recommended).
I have tried both options. They both seem to work, the green bar moves but then I am faced with an indeffinate blank screen.
I have tried removing the battery, making sure there is a full charge and that everything is connected properly. The power button is lit up white and the WIFI button is blue.
Any advice would be greatly appreciated

Hello,
I see that you're having an issue booting the notebook up. You could be having an issue with Hard Drive in the notebook, Sometimes when the Hard Drive is bad it prevents the notebook from booting windows.
Try and test the Hard Drive in the BIOS. Follow this document and it should guide you through testing the Hard Drive and the memory.
Please let me know the outcome. If you have any more questions let me know.

Problem With Compaq presario V3500

Currenty i have used Compaq V3500 since september 2008 ( before i bought CQ40-308TU, since i feel satisfied with HP-Compaq product). but a few days ago, my notebook suddenly crash, after (unfortunally) my guarantee has expired. After i can solve the crash, and can enter into system, my ram only detected 1GB( i have been upgraded into 2GB). i tried to check and test whetever sodimm is dead. but after i check, the reslt for my sodimm is alive. i found later, the problem is on the socket for sodimm, one socket is dead. since my guarantee is expired, i tried to service at general notebook service centre. but they also give up for this matter. they suggestion is to change the mainboard with new ones, and this will be costly enough. could anyone suggest the other option to fix this problem without replace the mainboard with the new one??or this was already general problem for V3500 user from the start?( maybe v3500 is a failure product from HP-compaq?)
This question was solved.

With a dead memory slot your only option is a new motherboard. Yes, the whole V3000 line is a cousin to the Pavilion dv6000 line, which has not been a sterling performer to say the least.

Problem with Compaq Presario CQ60 Laptop

Periodically laptop will not turn on. I had a message "critically low battery". Tried plugging in and no response. couple of days later, computer responded and did turn on. This situation causes great distress as I fear work will be lost forever. do i need new battery? Please advise. Helene

Hi,
Let me summarize, your laptop won't start from time to time and you had (have?) a "critically low battery" message.
When your laptop doesn't start, plugging in does not help.
When you face the problem, try to remove the battery from your laptop, plug it in and try to boot without the battery.
Batteries are well known to cause that kind of issue and if your computer does start without the battery then you may need to replace it with a new one.
But before you purchase a new battery, have a look there :
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00821536&lc=en&cc=us&dlc=en&product=3791961
This tool will certainly help you.
Regarding your files, even though at that point there seems to be little to fear, you should always back them up as they are more valuable to you than any piece of hardware!
With an up to date backup, anything can happen to your computer, you're safe otherwise there is always a tiny chance they can't be recovered (it's impossible, as an example, to recover files from a stolen laptop...)
Cheers.

Intermittent boot problem with Compaq Presario V6305NR

On pressing start button, laptop starts, but blank screen comes. After every few seconds, it keeps on rebooting, but nothing happens.
I have tried pressing F10 and Esc button on startup, but nothing happens.
Moving finger over multimedia touch buttons causes them to beep.
Few times, it shows the BIOS, but does not detect the hard-drive.
Very rarely, everything works fine and OS boots and works fine (without any sign of problem).
I replaced RAMs, hard-drive and DVD Reader in other laptop and there they worked absolutely fine.
I even tried removing the battery, connecting external monitor, keyboard, but nothing worked.
BIOS version is F.3D.
When opened, CPU fan and heatsink were dustfree.
Product Specs: HP Presario V6305NR, 1.6 GHz AMD Turion™ 64 X2 Dual-Core Mobile Technology TL-50, 1024MB DDR2 System Memory (2 Dimm), NVIDIA GeForce Go 6150 (UMA)

After few days my laptop stopped starting.
It showed no activity, as its motherboard had got fired up.
It was fault on their side (the faulty BIOS fan control algorithm), that let the motherboard to over heat.
I updated the BIOS, but it was too late by then.
Luckily my laptop was still in extended warrenty period (2 years from date of purchase).
I sent it to their service center and they repaired my laptop free of cost.
Its working fine now.

Problem with Compaq Presario F700, F767NR

I am having trouble with my laptop,
-The bottom gets hot fast
-Shuts off unexpectedly (it is almost like the battery dies but it is within 30 minutes or less of the computer being fully charged)
- When the computer is started up the screen that has the horizontal scroll bar, it will stay on the screen not leaving it until the computer is restarted manually with the button and the computer is restored. ( I believe there is a correlation with the installation of updates and programs makes this more likely to happen)
-When the computer is on and the lid is closed, when it is opened again it takes and unusual amount of time upwards of 5 min to get a picture to show up.
I would greatly appreciate any help anyone could give.

try cleaning the fan. I had to open mines up and clean the fan real good and also put new thermal paste on the cpu also

Hi,
The only option for a modem if one is not bought as an option would be a USB connected modem. U.S. Robotics makes one. Take a look here at NewEgg. It is unfortunat that this laptop does not come with an express54 slot.

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

Mail and iPhoto Problems with sending photos.

Mail and iPhoto Problems with sending photos.
I have this problem that started a while ago and seems to be getting worse.
Here are the different scenarios.
-If I try to share a photo to email within iPhoto, it will insert the image file name in the mail message, but no image icon or opened image. In iPhoto Preferences under General I have chosen to use Email Photos using Mail.
-If I choose to use iPhoto to send the photo, it will compose the message and the photo is viewable. If I send the message i can view the photo within the email I sent to myself. Nothing happens when I double click on the photo in the Mail message. Nothing happens when i control click on the photo in the mail message. Nothing happens when I try to drag the photo to the desktop from the mail message. When I try to save attachments from the email and choose a place to save it, the save button is grayed out and it cannot be saved. When I check the mail message it says there is an attachemnt but there is no file size listed.
-If I use the stationary within Mail app I cannot drag a photo into the placeholder, I get a circle with a line through it symbol when I try. It happens if I try to drag a photo from the desktop or from the media browser within Mail app.
-If I drag the photo to the desktop from iPhoto, I can double click it on the desktop and it will open in Preview.
-If I then control click on the same photo on the desktop and scroll to share/email, the generic photo icon will be inserted in the mail message. If i double click the photo icon in the mail message I get a message it can't be opened because it is empty.
-If I drag that same image to the mail message body the same thing happens.
-If I send that email to someone they cannot open the image file.
What I can do:
- I can drag that same image file on the desktop to my dropbox folder and it will upload. From there I can go on my iPad and download the photo and send it through email just fine.
-I can open the same image file on my desktop in Preview, I can copy and paste it into a mail message and the image will be viewable in the mail message by me and by the recipient.
-I can drag that same image on the desktop to my safari browser window and it will be viewable in the page. i can then copy and paste that image into a mail message and it is viewable in the message. I can then send that email message to myself and i can control click on the image and get all my options. It also shows as an attachment with the size of the image file in the mail message.
I can send that message to someone and they can see the photo and open it fine.
-If I send that same email to me I can see the photo within the mail. If I then drag that photo to the desktop I cannot use it again to put in an email as the same problem happens again.
I have tried all scenarios in my user account, another users account and in a guest account. The same happens in all. I am guessing because of this it is not a corrupt preference file, unless all of the preference files are corrupt. The guest user account I added a new email account so it was brand new and still had the problem.
I am stumped, all and any help is appreciated.

Another problem that may be related….
I have Snapz Pro. I used to be able to save the snaps to my desktop or a folder. Now when I take a screenshot and try to save the file to my desktop or a folder on my desktop I get this message "Files cannot be created in the selected location. You do not have permission to write to the selected location. Please choose a different location." I have found that i can only save the file to the clipboard. I have repaired permissions many times and still I have this problem.

You can check you Adobe account online to see if the serial number is registered under your account. If not then your only option will likely be to contact Adobe Support directly thru chat to see if they can provide you with a/the serial number. For them to do so will require you being able to prove ownership.

If it's happening on all the apps that you've downloaded from the App Store, but not the Apple built-in ones, then try downloading any free app from the store (as that appears to reset something) and then re-try them - the free app can then be deleted.
If it's happening on all apps then try closing them all completely and then see if they work when you re-open them : from the home screen (i.e.not with any app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of each app to close them, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't work then you could try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
