Problems in Compaq Presario C785 TU

On last Oct. 25, 2008, I purchased a Compaq (HP) notebook - C785TU from Comnet Vision India Pvt. Ltd. At the time of purchasing the laptop was not properly packed (plastic sheet) and the salesperson said that its a fresh one & there is no need to worry. I believed him & bought that Lapt. After few days only its sound device stopped working & when i went to that vendor he said its a virus problem. Though i had already installed the antivirus, he insisted me to installed it again. I agreed with him & again paid him Rs. 400 for the service (repairing of sound drive). But again within a week it again had the same problem. Besides this, there is another problem in the battery also because it gets very hot while charged. The salesperson denied & said it natural. Now a days, mean after six months of that purchasing i am facing the same problems of sound, battery & camera also.
Now, please suggest me what to do?

Installation problems in Compaq Presario V2617LA Laptop

Hello,
I am new in all of this Unix-Linux world and I need some help, here's my problem:
I have already partitioned and prepared my HDD to install Solaris, Windows and maybe Fedora (if someone recommends a better Linux it'll be appreciated), all of those three partitions perfectly identified and ready for the OS (it happens that I learn quickly, but I'm still new on this). I perfectly pass all Solaris 10 11/06 installation windows and requirements and Solaris begins installation, BUT when it all looks great, the installation (progress bar) just stops moving having 209.29 MBytes remaining and installing the 'Solstice Enterprise Agents 1.0.3 files for root file system', the wierdest thing is that the little slash-dash at the end is still turning around, the working processor light is on and nothing freezes (except when I navigate through the menu options), I have waited for a whole day and the installation does not finish and even re-downloaded Solaris and burn the image again two times and nothing.
Could it be a hardware compatibility problem? What do you think?

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.

Touch pad problems on Compaq Presario C56

Hi,
1st time poster here, so I hope I'm in the correct forum for this.
I recently purchased a Compaq Presario C56 with Windows 7, and already the mousepad/touchpad is developing problems in that it is quite slow and sometimes fails to respond to any touch from the finger tips. It is noticeably worse when the using the laptop when the battery is charging.
I have installed the latest drivers for the touchpad, and in terms of other software that I have installed, I have AVG free running and a few other applications installed such as Blackberry Desktop software, Google Chrome, Microsoft Office.
Is there any know issues similar to this with the touchpad?
Thanks

Power Problem w/ Compaq Presario C700!!

The other night I was working on my friends compaq presario c700. I was using the battery power. I was running a pre-bios .iso file program, due to password complications. In the middle of running the program to reset the admin. password, it turned off. So I plugged in the A/C cable. After pressing the power button, the led that is represented by a little Lightning Bolt flashed 5 or 6 times and then stopped. The laptop did not turn on. Even when I have the A/C plugged in, I see no led light showing that it is charging. I don't think my software that I was running could of caused this, or could it of? What steps should I take in fixing this problem? Have these models been known to have issues like this? Any help would be appreciated.
Thanks so much!

Based on you saying the LED flashed 5 or 6 times, this generally means the battery is fully discharged. Do you have access to a volt meter or multimeter?

No bootable disk problem on Compaq Presario CQ42

Hi,
I recently ran into a problem with my Compaq Presario CQ42-117TX laptop. I had a few regular updates installed and when I tried to restart the laptop to complete the update, it booted for a longer period then usual before flashing a blue screen for a second then blacking out.
When I restarted it again, it said there was no hard drive detected. I ran a BIOS system check and it couldn't run a quick test on the hard disk. When I try to turn it on normally, it goes to a black screen with a few details on the hardware inside and the last line reading 'No bootable disk -- insert boot disk and press any key'.
Any form of help would be much appreciated.
Thank you!

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

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.

DP-K

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?)

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.

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 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 :

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.

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.
