(or the reverse)learn that the BIOS must be able to recognize the processor in the POST process.(for sure lots of causes other)does it do that (laptop) with the main battery the huge heavy battery , that is now shorted and dead.?you post and not even say desk or laptop. wow.is it a Proliant Server? or Z600 with 2 non matching Xenon processors, gee, must I guess it all?>why not just post your service tag data.and say what OS is running, even windows servers.the HP manuals on your PC clearly state what processor on that exact model and P/N on the service tag.clear as day.as will the hp parts surfer.varies by country too. see this, if you answer all the questions there, bingo what yours had and what processor options are supported.on newer PC HP 10 years or less the BIOS update page also lists added processors under"details" there you go.http://partsurfer.hp.com/search.aspx

had this laptop myself, you need to remove all the drivers for the wifi and delete the files and folders.. download the driver from HP, reboot the laptop and it should install the windows driver. reboot again and then install the HP driver, when you have done this and its working make sure windows cannot update drivers ever again as windows installs wrong drivers. windows 10 is prone to installing the updated drivers that are not compatible with this model. like mouse pad. max version is 18. windows puts 19 on and it makes over driver incompatible.

no PC stated, (model)? no OS stated, windows what.? that means the drivers are wrong for this PC and its unstated OS. you do know compaqs go back to 2001 and hp portables back to 1984, we can not guess PC models, and they are not all the same. or means corrupted OS, or virus infected or worse. the word compaq means little and the name ended in 2013

thanks but............. and is and Obsolete PC. at HP and MS. sr1902uk (England?)

1. what OS? drivers match a OS, XP?
2. sure some makers of mobo offer drivers that HP ended. sure.
3. so does the unstated NIC chip maker offer drivers but not for all OS in most cases.
4. The best way to work on old PC is run the PCI scanner(ask)
5. identify the chip maker and model (ven=x dev=z)
6. then we can get any driver, for any OS if the chip maker has one, and many dont. for newer OS. (and ther reverse)
7. Finding drivers for old PC is not easy, (for me sure) but for most, it's very hard and the risk of getting virus high.!!
8. ask how to do it, using the scanner , lacking HP support.

1) Is the battery charged? 2) If OK, plug in power cable and switch the power off and on at the socket. 3) Contact HP using the link below: https://support.hp.com/us-en/product/Compaq-Presario-CQ56-Notebook-PC-series/4247498/model/4308224

CQ-nnnnn what is nnnnn , may Cq57 made, all different nnnnnn QC-100,.-200.,300, 400, series your service tag tells you the full model number. nor the OS (unstated) XP, VISTA, W7 or W8? this is what was used for the full series of production runs. and they are NOT THE SAME. tell what BACKLIT means. LEDs dead but at least name ONE>? Please tell the helper this. what OS first.? tell exactly what Backlits (lights) fail, name them. caps lock or ? what? give examples of what fails and what you are attempting to do.. on my newer HP, there are no keyboard lamps at all not one but the HP has back panel that glows for that. but needs the HP software loaded to make that work only HP software works on that feature, period. what operating system is this.? the CQ57-400 is the last series is this it. why must i guess? support for it is limited to this. ill guess 400 for you as 1 example then ill guess w7 32b then you see this and load all these driver. https://support.hp.com/us-en/drivers/selfservice/compaq-presario-cq57-400-notebook-pc-series/5186820 now il guess 100 here https://support.hp.com/us-en/drivers/selfservice/compaq-presario-cq57-100-notebook-pc-series/5059083 looks like last one made was 2012 (Compaq ended in 2013 at HP) so has support until 2022. at HP.com load all your drivers for you PC on the HP page. skip BIOS. (line) the problem here is HP used 2 processors here. Intel and AMD mixing drivers up is problematic. here. takes skills to do this. why not ask at HP do this is. real HP forums....

This depends what version of Windows you are running, if you are running an older version, say Windows Vista, there is a known bug with the ISATAP Adapter, essentially it is an IPv6 protocol, and is not needed. It should have no impact on the operation of your wireless card and is completely fine to use with the yield sign. It may have been there for some time before you noticed. The connectivity is most likely unrelated. If there is a yield sign next to you wireless adapter i would recommend re-installing the driver. You will need to search google for the driver and re-install. Sometimes manufacturers will have drivers on their websites and you simply enter you laptop model and year and select wireless card. Other times you will have to do a thorough search on google. Dont download any program that will search your computer for missing drivers, they are a scam. Try searching for your model number and Compaq. If you cant find exact model number of your laptop, a general Compaq driver may work. Can you still connect through wired ethernet cable? What do you mean by wont connect? Do you mean connect but there is no internet? Or you can see the wireless network but not connect? or you cant see any wireless networks at all? I have also run into issues where the saved network configuration is corrupted, and trying to join a network and enter the password is futile, even though I have previously joined and it is a trusted network. In this instance, I deleted all network settings and all saved configurations associated with this network and joined again from scratch, which rejoined first time.

I am assuming you are installing Windows 8 as this message is related to Secure boot on Windows 8. Secure Boot needs a System with UEFI supported BIOS and Secure Boot Enabled in the bios. Secure boot requires drivers to be signed and certified to run with Windows 8. Some of your hardware may not be supported because of this, and thus Windows will not boot, and shut down to prevent damage. See this Microsoft link for more details: Secure Boot Overview

Try re-installing the application, if this does not work then have a look at the publishers website for FAQ's and the forum, they can be very helpful.

You probably have to "tell" the TV to see the monitor. In other words, there might be a VCR/DVD/VGA(computer) setting/switch on the TV menu. The TV might not find the computer automatically like a monitor does. Good luck.

if your "F" function keys are a second function of the keys they are on there will be a key, usally located in the area of the lower left corner of your keyboard. If the "F" functions are in color, so will the key that activates them. The idea is that you hold down the Fn key while striking the selected "F" key

Open Device Manager and revert to the earlier drivers, or just delete the device. Restart the computer and try other drivers if you're not happy with the current drivers. Don't get updated drivers from Windows Update, always download from nVidia or whatever graphics card you have. HP should have drivers intended specifically for your notebook, which takes their setup into account..

LOL what mouse, ? a USB mouse or the MOUSE pad.?> tell what Persario it is, lots of models made. it has model number for sure use that everytime you post and tell what OS it running there solutions all depend that. and what mouse you own. my guess some Lenovo USB mouse A Persario name is a desktop and a lamptop it has no fixed form,, that work answer for say a desktop, no mouse pad laptop I guess running windows XP the virus magnet and is infected or the mouse is bad, try doing this. 1: try that bad mouse a good pc. 2: try a good PC mouse on the bad PC. see?? hardware is eliminated from the cause. or if all mice fail ,that is bad Software. top reason bad mouse driver. but if XP , the online drivers are gone now. so tell what PC this is what OS this is and answers can focus way better. ok? the control panel has mouse icon click that and test the mouse. it has a click speed test there, try that,? in device manager is the mouse driver bad>?
