Compaq presario co50-210us - failure to startup

We have a Compaq Presario CO50-210US Laptop, yesterday the screen began to dim, and access to programming or the internet became slow. Eventually the screen went dark, and the computer shut off. Since then, any attempt to power-up the computer results in the 3 FRONT lights flashing 3 times and then nothing. Power supply is correctly attached and plugged in, and a hard reset did not help, and I cannot think of any other options. I recently used can air and blew out the dust from all the openings I could find including removing the access panels for the hard drive and memory modules. This computer has a history of getting so hot that it has shut down in the past, and not re-start until cooled down, (half-hour or more), even though it sits on a cooling pad at all times.
Any suggestions on what to do next? And what the blink code means? Any help will be welcome.
Solution:
Apparently, the three flashing lights mean "The Wall Charger is DEAD, and the Battery is Drained". Purchased and plugged in a new Charger, and the computer runs like before.
This question was solved.

Can you upgrade the processor in a Presario CQ62-210us

I just bought a compaq presario cq62-210us, and I didn't realize that it had a single core celeron 900 processor, so what I was wondering is if it is possible to upgrade to a dual core processor.
I know that it is hard to upgrade the processor on laptops, but is there a specific chip that would fit in this model? If not, then is there a simuilar model that has the same internal configuration, that I could just switch the processor with the model I currently have?
Thank you.

Please post your full product Number

Compaq presario cq60 210-us bios update failed

I tried to update the BIOS of my Compaq Presario CQ60-210US notebook using the driver downloaded from the HP Support website. The update failed, the computer locked up and would not take any input from the keyboard or the mousepad. I did a hard reset and now the notebook won't boot at all.
I tried following the steps to restore a corrupted BIOS (windows key + B + power for 3 seconds) several times but the notebook still will not boot.
There are instructions for using an HP_TOOLS USB drive to restore the BIOS, but I can't figure out how to create that USB drive. There are no links and no instructions to create it. When I search HP.com it takes me right back to the same page.
Help!

See if someone will reprogram your bios here:

Mother board failure in Compaq Presario C770TU Notebook PC

Dear,
My

please suggest me what shall i do.

Hello khadkemm,
You mention you are performing an installation of Windows. Is this an upgrade situation? What operating system is currently installed and what are you upgrading to? You may want to take a look at this page, and see if it helps.
You can replace the motherboard by looking at your Maintenance and Service Guide, but the software hanging up does not necessarily mean the motherboard is defective. Are you experiencing other issues and error messages? If so, what are they?
Please reply with more specifics and let me know if the info above helps.
Good luck!

Compaq Presario Blank Screen

Hi, I've got a Compaq Presario CQ61-406SA Notebook, and the screen's just displying a black screen. The backlight's on, and I'm using an external monitor to type this so I know the laptop's running fine. I'm wondering if I need a new screen, or is it something else? Thanks.

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.

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?

HP Compaq Presario CQ60-320sa vista product key fade.

Hello help me please- HP Compaq Presario CQ60-320sa
I got HP Compaq Presario CQ60-320sa and the window vista product key is fade. I can read first, second and last.
Now my earlier hard disk got crashed because of bad sector and I have to installed new one which I did now I want window vista product key for activation and the sticker back of my laptop cover is fade can't read all product key. If I download HP- USB RECOVERY FLASH DISK UTILITY does this software let me reset my laptop to factory version and won't ask me for product key. Thank you for your time.

I understand you need a product key.
An HP recovery should have Vista already activated with the product key for the system. Do you have access to recovery media for this system (disks or a USB recovery drive)? If you can perform an official HP recovery, there shouldn't be a need to get the product key off the bottom of the notebook. The utility you mentioned only creates the media from the recovery partition on supported systems. Since the HDD was replaced due to a failure, I am afraid that the flash disk utility will not be of use as the recovery partition is not present on replacement HDDs.
Some users have had success with contacting Microsoft regarding the unreadable product key. They might be worth a try.
According to this page, the HP part number for the recovery kit for this system is 515724-031. You might be able to find the appropriate recovery disk set from a third party ensuring the part number matches. You might want to verify with HP that the recovery disks are not available from HP before using a third party source.

Compaq presario problems with vista

Hello, I am having major problems with our compaq presario sr5233wn desktop, os windows vista home premium. It started shutting down about ten days ago randomly, then started with a blue screenthat has displayed different messages... I have completed 6 different restore points and this didn't work... I then backed up my personal files and performed a complete system recovery installed on the pc...it worked great for about half an hour then the freaded blue screen popped up and I had to shut it down...i did this three times to no avail...then I did a complete recovery from the two discs I made shortly after purchase...that has not worked either...does anyone out there have a fix for this..I need my ole puter.
Thanks Elmer

Hi Elmer,
Sounds like the first thing you need to do is test for a hardware failure. Check out Testing for Hardware Problems Using Hardware Diagnostic Tools (Windows Vista) and since it sounds like you are having problems running Windows for very long, skip to the bottom to the section called Using Hardware Diagnostic Tools when Windows does not open. Run the tests and report back what you find, if anything fails then there is probably a hardware component that needs replaced, possible culprits include the memory or the hard drive based on the symptoms you are describing. If everything passes, post that back as well, and let us know, and we can look for other causes of your problems.
Good Luck!

Compaq Presario CQ71-420SM booting problems

Hi,

Removed the ram that is left one module than replaced it with second, tryed to change slots with both modules. no result.
Laptop be it on battery or without one but with power plugged in needs about 10 sec to eaven spin cooler/s and promptly shuts down - blank screen all the time.
Now ONLY when battery and power adapter is in i get white led flashes (led located lower left from touchpad - not the one near where i plug in power cord) in following durations:
- = short duration of led light
-- = normal duration of led light
--- = long duration of led light
1) -- -- -- -
2) -- -- -- --
3) -- -- -- ---
than fiew moments pause and all over again
i have read somewhere that this is most likely vga failure now can You please verify this for me or give me valid info on what can it be or what should i look for?
i have looked for error codes on fiew laptops, could not find specialy for this one but this is one of the links
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01443366&lc=en&dlc=en&cc=uk&lang=en&rule=26781&...

My compaq presario cq57 wont download any new files.

hey guys I'm in need of some help. After doing a system recovery my computer will no longer download any new files from the internet. from browsers to games I've tried it all. and nothing will download. it keeps coming up with a message that says that it can not find the file that im trying to use. so i was wondering what might be causing this and ho wi would fix this, if its possible to fix.

Hi @christian12 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your Compaq Presario CQ57 Notebook and issues with installing drivers. First, try to click the Windows icon, type services in the Search box, and then click or tap View Local Services. Scroll down to the Windows Installer. Startup type should be - Automatic, and Service Status should be - started. Restart the computer after this step and try installing again. If this is not automatic and started that is why you can not install drivers.
Please note remove any and all USB devices. Disconnect all non-essential devices, as these could cause some issues.
Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system at the time of purchase.
Hope this helps.
Thanks.

Bios on compaq presario cq57 keeps recovering every time I boot

Relatively new laptop. It is a Compaq Presario CQ57 running windows 7 64 bit. Up untill recently everything was fine but about a week ago it started failing to boot and then after turning it on and off, going into the bios recovery. It goes through this (sometimes more than once) before finally giving a message saying bios recovered, error 500 (and to look here for assistance). The issue seems intermittant. Sometimes it boots fine, other times it takes several attempts with the automated recovery. I think the automatic update for the bios has run once or twice, but I didn't notice any updates immediately prior to this issue starting.
Does anyone have any answers. Thank you.

No ideas anyone? Took me about an hour to get the thing to boot today. Several attempts at turning on and off during which it wouldn't even POST, and then once it did post, the bios recovery system ran through several times before I finally got back into windows.
The exact computer model incidentally is a CQ57-364EA.
I'm trying to figure out if this is a software issue or whether there is a hardware failure somewhere. I'm figuring it's software, because when the computer does finally boot, it works normally.

Compaq presario cq61 DVD recognition

Greetings all. Compaq Presario Windows 7 The DVD burner won't recognize some of my DVDs including some of my backups. When I insert a disk, I either get nothing, like the disk isn't in the drive, or I get a message asking me if I want to format it. None of the disks in question are rewritable. DVD-R. HP DVD-R disks work, but other brands don't. RW disks work. Help!
This question was solved.
View Solution.

You can try a DVD lens cleaner available at any store that sells DVDs. That is a longshot. If it reads some types of disks but not others that means a failure of one of the multiple lasers and the only fix for that is replacing the drive. The drive is easy to remove and replace and the part is not too expensive. Where do you live?

Compaq Presario 2135US Reboots For No Reason

I have an old Compaq Presario 2135US notebook (purchased 6/2003). It has XP Home Edition SP 3 and lots of software. It has a 30 GB hard drive with 5 GB free space. I have replaced the battery and added the maximum memory (1 GB of shared memory). Lately it has been rebooting about 1 to 2 minutes after startup. There is no blue screen, no you shutdown improperly screen and it reboots cleanly to the log on page. So far this reboot happens only once each time I use the computer. It normally happens when I am not actually using the computer. There is noise associated with the reboot. It sounds like a switch opening or an electrical arc. The noise is very short and the computer reboots and operates OK thereafter. This noise and reboot happens randomly maybe 1 in 5 times I use the computer. I was considering giving it to one of my grandchildren. There are lots of pictures and documents on the disk that if removed would give a reasonable free space on the disk.
Does anyone know what the problem might be.
Any help or suggestions would be appreciated.

It may be overheating. If you put a fan pad (one or more fans in a pad powered through USB ports) underneath it that might help. You could also try to put a vacuum hose near the fan and exhaust areas and see if you can get out any dust.
