Compaq presario cq56 wont boot even to BIOS.

Compaq CQ56 laptop Recently after shutting it down normally I cant boot it up again. The battery and the power adapter are good. The CAPS lock light flashes every 2 seconds. The orange wireless light remains on. The screen is totally black.
What i have tried so far without success:
1. Removed the power cord and the battery and pressed the power button for almost one minute.
2. Tried to boot only with AC power without battery
3. Tried to boot without RAM modules (also changed RAM modules without success)
4. Removed the CMOS battery for five minutes and put it back again
Any help will be appreciated highly please!

Hello Udinov,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I have read your post on how your notebook computer is not able to boot into the BIOS, that the CAPS lock is blinking, and I would be happy to assist you in this matter!
To find out the meaning of the blinking light sequence, I recommend following this document on Computer Does Not Start and the LEDs Blink or the Computer Beeps. This should help determine the cause of the blank screen, as well as the interpretation for the blinking CAP locks light.
Please re-post with the specific blinking-light pattern with the CAP locks light, and I look forward to your reply!
Have a great weekend!

Compaq Presario CQ61 Wont Boot

So Like Most owners of the Presario, My Computer wont boot. Its a blank screen and the LED blinds towards BIOS Corruption but since I cant even get out the blank screen Any help would be very well indeed Helped. Below is Info and things I've Tried
Computer Type: Compaq Presario CQ61-319WM
Operating System: Windows 7
Warranty: Gone
Bought: 3 Years Ago
What Happened when this all started: I was drawing on photoshop, I closed it so it would go to sleep mode. I left the house for an hour to shop and come back to this blank screen and LED blinking Lights (Twice)
Last Six months had To System Restore Twice, An Update back in March made my computer not work so was forced to system restore.
Things I've Tried:
*Hard Reset More than 5 times, nothing worked
*Bought New Charger
*Bought New Battery
*Removed/Reseated my two 2gb Ram sticks. Switched them
*Removed HDD/Battery to see if it Was the HDD
*Took apart computer before I knew it was the BIos to see if it was the moniter or if the wires got exposed or snapped
Than I tried to get into the BIOS Recovery, tried the Win button +B button/Power, f2 and f10. Nothing gets my computer off the blank screen.
I Think Ive gotten everything Down. Should I send it in even though it would be smarter to just buy a new computer? Im at a lost of what can be done . Almost Every person with this problem got fixed by Hard Reset. I dont know how to deal with BIOS. So Please Help If You can.

The troubleshooting steps mentioned in the following weblinks might help you to resolve the issue:

Compaq Presario 6150b wont boot - no BIOS screen - powers on and off repeatedly

Hi, i bought a 6150b from a company auction. Everything worked perfect for the longest time. Then last week i went to go turn it on, and all it does is run the CPU fan for a couple seconds, flash the AC LED about 7 - 8 times, and while thats flashing the power and hard drive LED’s stay solidly lit. Then it completely turns off. This all lasts about 3 seconds at the most. That’s what happens when on battery power.
When on AC power, the same thing happens, except it continues doing the cycle over and over again until I unplug it.
I think it might have something to do with the LCD monitor, since it does not even show a slight flicker at all. No color change like it would from when turned off to a black back lit screen when turning on….simply nothing.
I opened her up (no warranty anyways) and checked all the connections for the keyboard, monitor, DVD drive etc....also reseated them as well, with no luck.
Pulled the both RAM modules and reseated them as well, nothing.
Pulled the battery as well, no change. Still cycles the same over and over again while on AC
There are no audible errors codes (real nice HP...), and im lost at this point.
Any and all suggestions are greatly appreciated.

I just wanted to say thank you form the depths of my heart to say thank you and god bless you carol I know there is prbably more than one carol working customer support but she was my escalation represintative.All my best wishes go out to her and the repair departent for all the help.I cannot say enough good things things about her.first i sent in my pc and it took days to get my box then another 3 before they got ,then they sent it right back without repair i thought it was hopeless.But I got in contact with Carol and now everything is fine my pc is being repaired and ill be getting it on the 23rd.Thank god for the nice people in this world without her help im sure i would be starring at a useless pc.So in the end they did right by me and will definaltely be buyingan hp the next time i buy a pc.Also I cant forget the the peopole who actually fixed it you have no idea how much this means to me this pc is my baby and because of this i will always buy hp products.But whatever you avoid emachines i had an older pc i was trying to get working and they wanted to charge me 59.99 for 30 mins of tech support 129.99 for 90 minutes.Thats just ridicoulus.Anyways i cannot thank Carol and the reapair staff enough for getting me my baby back in such a timely manner.if there is anywhere ican rate her help please moderator send me a survery r something so i can express my gratitude.HP ROCKS

Compaq Presario CQ56 219-wm CPU compatible upgrade

Hi I am a performance pc enthusast and I wanna upgrade the stock cpu celeron single core 900 cpu of my Compaq Presario CQ56 219-wm laptop.
Can u tell me what following cpu will work with your current F.15 bios?
Intel Core Duo Mobile T9300
Intel Core Duo Mobile T9500
If not those what would be the highest cpu supported?
Thanks

Pretty sure the GL40 chipset is used only for Celeron/Pentium Dual processors. Notice that no Core2Duo was offered on the CQ56-200 Intel line. Just Celeron and the T4500. The GL40 was a special chipset for "value-oriented applications".
Service Manual
This is anecdotal but you have some folks who claim to have successfully installed Core2Duo processors on GL40 laptop motherboards, including at least one HP. However, note the "official" compatibility list and take other claims with a grain of salt:
http://www.cpu-upgrade.com/mb-Intel_%28chipsets%29/GL40_Express.html
In other words, it might work even likely will work but it is a gamble.

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.

Compaq Presario CQ56-115DX Problems

Hello,
I have a Compaq Presario CQ56-115DX Laptop. It is still under warranty. Within the last week the power of the laptop has been messed up. When I have the laptop unplugged, which I don't very often, the laptop shuts down after an hour without any warning. So I plug back in the laptop and it still shows anywhere for 40-70 percent battery left. Why is it doing this?
Thanks

Hi,
First of all, shut down the notebook, unplug the AC Adapter, remove the battery, and then hold down the Power button for a full minute.
Now, plug in the AC Adapter without the battery inserted, start the notebook, open windows Control Panel, open Device Manager, expand the entry for Batteries, right click on and the Microsoft ACPI Compliant Control Method Battery and select Uninstall - do not uninstall anything else here. When the uninstall is complete, shut the notebook down, unplug the AC Adapter, re-insert the battery and then start the PC on just the battery. Windows will automatically reinstall the driver - leave Windows running for a few minutes. Shut down the PC again. Now plug in the AC Adapter ( with the battery still inserted ) and start the notebook to see if this has helped the issue at all.
If the above has not helped, download and run the stand-alone battery test utility available on the page below and see if this reports any problems with your battery.
http://h20239.www2.hp.com/techcenter/battery/battery_ts.htm
If this reports a problem with the battery ( or even if it doesn't, but the problem is still occuring ), contact HP and arrange to have the battery replaced/notebook repaired under warranty.
If you live in the US, contact HP Here.
If you are in another part of the world, start Here.

DP-K

Compaq Presario CQ56-110US will not load up.

So.. the moment I press the power button, my Compaq Presario CQ56-110US notebook, will not load up. It only show the Compaq logo screen flashes black them shut down and restarts the process. It never makes it to the Windows login page.

Hey @rajpodn ,
Welcome to the HP Forums!
I understand you're looking for info on swapping out the CPU in your notebook.
You will find everything you need here: Compaq Presario CQ56 Notebook PC - Maintenance and Service Guide. The instructions you need start on page 75. Keep in mind that the CPU itself may not be the issue, it could be the socket on the motherboard preventing the notebook from reading the CPU, so even replacing the CPU may not work, as you may need a replacement motherboard. I do not suggest replacing the motherboard as doing so requires HP Proprietary software to reinstall the Service-ID necessary for reinstalling Windows.
*Caution - If you do install the new CPU be careful with the thermal paste. A small pea sized amount should be more than enough. Put the paste in the exact center and carefully spread so there is a fine layer almost to the edge of the CPU. Remember that the heatsink will press very firmly onto the CPU and spread the paste more and you don't want any squishing out as this can cause electrical shorts if the paste has a high metal content.
The part you will want is: AMD V140 processor (2.3 GHz, 512-MB, L2 cache, 1066 MHz, 3.2 GT/s)—singlecore 25 W. The part number for this is: 616333-001.
You can order the CPU directly from HP here: HP Part Surfer, but you may be able to find it cheaper on sites like eBay, Amazon, or Newegg.
Hopefully this covers everything you're after!

Compaq presario cq56 115dx will not power on blinking lights, not a disk drive problem

I own two identical Compaq Presario CQ56 115-DX, and the one I use every day stopped powering on. Shows blinking caps lock light and orange WIFI light does not turn blue to turn on. The fan powers on, but the screen doesn't come on at all. I tried hard resetting several times and it didn't work. I swapped the hard drive of the malfunctioning CQ56 to the other one that was working normally, and it works OK normally. No hard disk corruption or problems.
Any idea how to fix this problem laptop?

Compaq Presario CQ56 beep while working and working temperature

Hi,
I Have a Compaq Presario CQ56 with Windows 7 Ultimate (32Bit), ADM V140 CPU, 2GB of DDR3 RAM and an AMD Mobility Radeon HD 4250, and a SAMSUNG 250GB HDD.
While i am playing some random games like Need for Speed Carbon, Need for Speed World on Low-Medium graphics, i hear a long beep and then a click from the laptop, somewhere from the DVD-RW Drive. It only occured twice do far. The laptop works normal tho after the beeps.
Also, the temerature is worrying me, it goes up to 75C while playing, but goes down to 60-65 while internet and around 54 while idle (lid closed).
Sorry for my grammar i am Serbian.
Thanks in advance!

Those temperatures are a bit high, but still well within normal range. We see a lot of people reporting temperatures in the 90C ranges. The beep is a mystery to me.

Hi
You have a couple of options as I see it please run the Hard drive and Memory test check if both off them passes. Then you could order the Recovery disc from HP Technical support or from the web link given below.
If any test Fails you need to replace the part.
How to Run the Test
Order Recovery Discs for Windows 7, Vista, or XP
Let us know how it goes!
