HP Compaq Presario CQ61 :: Serial Number Not Found Message At Boot
Oct 9, 2014
Just last night Serial I got "Serial Number Not Found" message at boot followed by " Windows 7 Compilation 7601 this windows copy is not genuine".
I tried to insert the product key of the label of the notebook but that didn't solve the problem.
The Nootbook is a HP Compaq presario CQ61 Notebook PC (CQ61-325SP)
S/N C NF 9376 MZL and I am running Windows 7 Home Premium, Service Pack 1
Pentium (R) Dual-core CPU T4300 @ 2.10 GHz.

just wondering about doing a CPU upgrade on the above laptop, the current CPU is an AMD Sempron M100. I'm not to up on my AMD cpu's so not sure what the best upgrade would be. Also, what does the bios support, as there are many CPU's that will fit the S1 socket, but I guess not all will be supported in the bios, so does anyone have any knowledge on this.

Today, I was prompted by the HP Support Assistant software that a BIOS update was available, so I had the application download and install the update. When the computer came back up, it is stating the a boot device cannot be found.
I have an HP ENVY TouchSmart m7-j010dx Notebook PC running Windows 8.1. Laptop was functioning just fine prior to the update, which means I probably shouldn't have allowed the BIOS update.

I'm trying to locate the serial number of my laptop and it appears to have been removed. It's not under the battery. Is there somewhere in the operating system that I can retrieve this information?

an Inspiron 1720 with 1440x900 - TrueLife - screen.
As you probably kwon, I get first the bad Samsung LCD screen.
Then I asked for a replacmeent by Dell and get the AUO LCD screen after replacement which is not better. (Bad view angle, backlight problem etc..)
I'd like to know what is the serial number of the LG LCD because it is better than the 2 others as I read on forums.
I think it is LP171WX2 but not sure?

Last minute question (and definitely a dumb one) - where do you find the unique serial number on our laptops (ie for use when declaring it with customs prior to leaving the country)?
I don't have the UPC code that the Sony registration site directs me to on my box, and on the bottom of the laptop there is no specific number that says "S/N: #########"..

I have a Compaq Presario CQ61-313us notebook, and i've just installed windows 8.1, then i realized there was a problem with my Internet, every time i open a website, i always get either a page like this: [URL] ... , or i get "Error: Gateway Timeout", though i can get to the website if i refresh a few times, but it's extremely slow.
Also, i can't download anything, I've been trying to download the .NET Framework 3.5 through Windows Features and windows Update, but in vain. I think that proves that the problem isn't from IE. I also think that it's the wireless driver's fault, but i'm not sure, and i don't know what driver to download. I tried updating it from the properties meny, but it says it's up to date. My wireless adaptor is Qualcomm Atheros AR9285 802.11b|g|n, V3.0.1.155.
Update: I think it's worth noting that when i download with utorrent, it downloads normally with my regular download speed, but other than that, i can't download anything.

I have a Compaq Presario CQ61-417SA Notebook PC operating on Windows 7 Home Premium. The laptop freezes at random times, sometimes minutes into use or an hour into use. It is not caused by clicking a certain program or file. I suspect freeze issue maybe caused by hardware failure, possibly the HDD.
Here's a few observations of the laptop and the things I've tried to diagnose or fix it. During a typical hang the HDD LED light is constantly lit. Have also had both blue screen and black screen freeze. No error messages. Hard drive gets very hot. Entered BIOS and run both Primary Hard Disk Self-Test and Memory Test using InsydeH20 Setup Utility but it passed both.Laptop has been fully reset to factory settings so it can't be because of high CPU usage.
While idle the CPU usage is usually in the range of 13%-25%, with a rare spike of 53%The hard drive is a Western digital Scorpio Black 2.5" 320GB SATA. The laptop is unused so wiping it back to original settings wasn't an issue but I would like to get it back to a useable standard.

I have a Compaq Presario CQ61 Product: VM9496Q2X Model: CQ61-319WM, that has a black screen when I power up. The wifi button stays red and the caps lock flashes twice. I believe this indicates a BIOS corruption failure. I have tried resetting by unplugging and removing the battery, and holding the power button for 30 seconds. I have tried the f8 key and the esc repeatedly at power up. I have also tried pressing the windows and B key along with the power key but nothing worked.

I have a compaq presario CQ61-420US with similar problems below, except I have a black screen, fan turns blinking lights are the same (num lock and cap lock) but they are flashing continuously every second or 2. I have tried the hard reset with the ram fix, connecting an external monitor, changing the battery, and the power adapter to no avail. I also used compressed air on the vents just in case was stuffed with dust since it will overheat and may cause problems, but nothing.
One option I can think of is purchasing a new MotherBoard, but I'm trying anything else before that.

I have a problem with my Compaq Presario CQ61-325ED. It won't boot. What I see is a black/blank screen, with the numlock and capslock lights blinking twice every couple of seconds.
According to the blink codes, it seems the BIOS has been corrupted [URL] .... Sadly, no adequate solution is given on that page.Win + B or Fn + B at startup does nothing, pressing all the arrow keys gives me a continuous blinking pattern (edit: I can't seem to replicate this anymore...). I have also tried creating a bootable USB-stick with a BIOS update, but I don't think I have done it correctly, for it never gets activated (the light on the USB never turns on).
Also, removing/resetting the RAMs or just one of the RAMs does not work. Neither does removing/resetting the CMOS battery. How to successfully create a bootable USB-stick with BIOS update for CQ61-325ED?

How to connect my Presario CQ61 Notebook to a Philips TV via HDMI under Windows 7. I checked the settings in the control pannel in Windows 7 and set them to multiple displays. Under the NVIDIA control panel I cloned the displays. Nothing happens, black screen on the TV with "no signal" message. The Notebook is recognizing the TV correctly by the way.
I already spent 2 hours on this. Tried various articles online, but nothing seems to work. The HDMI cable is OK. I successfully connected a Playstation console to the TV. Seems it's not a hardware issue, but something with the settings of my notebook.

I found the part number for the raid component in the Z-series. You just need two low-profile SSD, and you should be able to do RAID in the Z-series laptop without paying for RAID config from Sony.
Part number is A-1553-769-A
You can go here to purchase the part

You may be able to use this in the TT as well, but I'm not so sure about that.

got a Presario V2000 that will not boot whatsoever.
Upon pressing the power button, the machine starts up and displays the standard "Windows could not start properly" screen. Every option I choose, from the three Safe mode options, to the Last Known Good Config, to Start Windows Normally will not work.
I choose an option and everything goes smoothly, the Windows XP splash screen pops up & stays there for a few seconds, then goes blanks for a slightly longer length of time before a blue screen pops up. I can't remember the first few numbers, but the rest I'm pretty sure is accurate:
(a series of letters/numbers is here) (Registry File Failure)
The registry cannot load the file
SysCommandSysCom32ConfigSOFTware
or its log or alternate
It is corrupt, (something I cant remember), or not writable
Beginning dump of physical memory
Physical memory dump complete
Contact your system administrator or technical assistance.
.....and it pretty much repeats over and over in a continuous cycle like this until I power it off.
What I'm wondering is where exactly the problem lies? On the Hard Drive--where the drive itself needs to be replaced or the OS just wiped and reinstalled fresh.......or is this indicative of a hardware failure...which would mean this lappy is pretty much dead?

I have a hp tx2500z
When I turn on the power for computer there's a beeping noise coming from the hard drive I think and this message comes up in blue letters with a black background
" Boot Device Not Found
Please install an operating system on your hard disk.
Hard Drisk (XXX)
F2 System Diagnostics
When I run the system diagnostics for the Hard Disk Test, it says:
"Hard Disk Test Failed
Hard disk not exist"
What do I do? I went to the website but its suggesting that I basically may have to do a system recovery to the factory installed state...I have a lot of stuff I don't want to lose.
I also tried removing the hard drive and putting it back in, that didn't help either.
I called tech support and I still have my warrranty so I will be getting a Hp box to put my tablet in within a few days. But they told me I would most likely lose all the data I have saved.
Then I used a liveCD in hopes of backing up my harddrive but the liveCD won't even boot..unless im doing it wrong...( burn iso to CD, then load CD into laptop, and press f10? and/or turn on computer with CD inserted in and then let it load if it wants to?)

My daughter has a Compaq Presario 2100. She said she got a virus! I don't think she did. But the problem is it will boot and not run! I ran a test for Hard Drive and it didn't show one. I also tried to repair from disk, it said it didn't have a hard drive. Disk is the reinstall XP. Is this a virus? I think it is hard drive gone bad.

how to troubleshoot the Hard Disk (3F0) error message.
3F0 can be caused by 3 things
1. Bad hard drive or partition structure, erase the entire hard drive then use HP recovery discs to attempt reinstall of the OS and all partitions.
2. Bad hard drive data cable that connects it to the motherboard, replace the cable
3. Bad sata controller on the motherboard replaces the motherboard or laptop.
Now, the first step, is to test the Hard Drive out in the BIOS if you can get into it.
You will need to boot up the notebook and press F10. If you can get into the BIOS you will need to run the self-test. Here is a document showing you how to run the test. If you can't get into the BIOS I would suggest removing the HDD and then try getting into the BIOS again. Once you remove the HDD boot the notebook up again and press F10. If you can get into the BIOS, then the HDD is bad.
Here is a video showing you how to remove the HDD:

Presario CQ61-411WM
Operating System is Windows 7
Most of the time the laptop will not boot up and I get the single blinking LED on Caps Lock and Num Loc. However, if I am persistent and keep trying the start button it will boot up. After it boots up every thing works fine. I can even do a restart and it will stop and boot back up. But if I do a shutdown then I will have to push the start button several times (it will come up with the single blinking LED on Caps Lock and Num Loc) before it will boot up again.

I just got a laptop from Craigslist that I liked, its a Compaq Presario R3000 and the speaker was messed up. So I dis-assembled it and like started to fix the speaker, and when I got done I started to put everything back into place...Well when I got it done I turned my laptop back on and it powers on and the fans kick on but nothing pops up on the screen and it doesn't boot...

I have a Compaq Presario V5000 that will not power up. Fans and drives don't spin up. The odd thing is it will charge the battery when hooked up to the power supply. The orange lightning bolt is solid until it is fully charged then it blinks. I have a second power supply and I get the same result.
The laptop does nothing when I remove the battery and try to run in directly on the power supply. I have re-seated the memory, hard drive, DVD drive, WiFi, keyboard, touchpad, monitor, audio board and replaced the power button board.
I also checked the power level going all the way to the processor and all is well.
