I have an HP-G71-340US notebook that I purchased 11/29/09. When I power it up, a black screen comes on that shows 'serial number not found' and it also says that my copy of Windows 7 Home Basic is not genuine – but my computer came with Windows 7 Home Premium. In BIOS, my serial number is not shown either and I did pull out the little battery to reset it which allowed me to bypass the suddenly new locked BIOS that needed a password to enter. I'm sure this is a masterpiece created by my 6 or 9 yr old child while trying to play on my laptop.

Can I fix these two problems? Judging by the comments (blanked BIOS serial, etc) it looks like your computer has suffered a BIOS damage, perhaps because someone tried and failed a BIOS update (but usually the computer doesn't start at all) or by accident. You see, on modern computers these information are still flashed somewhere in the motherboard ROM, so could be subject to overwriting. If you can't use recovery DVD to reinstall the software (I expect the same result but I would give it a try) you should call HP and report this as a hardware failure. I have worked on a computer recently that this happened to. I was able to fix the missing information in the motherboard ROM. Here's the forum post that helped me:.

I started researching why this has happened. Your answer made better sense then what i could come up with. As for the 'Windows is not genuine' issue what i have discovered that with no serial number or any other info in the ROM then Windows itself will not activate for you.

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.

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. Sep 24, 2014 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. Oct 2, 2014 I have an COMPAQ PRESARIO CQ61 and suddenly is asking me for the admin bios passwordAfter 3 failure trials, it shows a code '76317137'.

Aug 7, 2009 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?

Download Picture Style 2017 Canon 600d. Oct 7, 2008 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? Jan 10, 2009 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: #########'. Oct 24, 2014 I have replaced my laptop battery and the icon now indicates 100% available but plugged in charging.On removing the power lead the laptop immediately dies.Should I have done something about callibration when installing the battery? Feb 3, 2014 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.
