HP ProBook - Popular Questions, Answers, Tips & Manuals

The only way I know to reset or clear the password is to know the original one. BIOS passwords are stored in Flash memory and therefore cannot be cleared by removing the CMOS battery like in the good old days.

I'm assuming your using Windows 10. Look at the keyboard. On the top row of buttons, just above the numbers, there are a series of 'f' number buttons. Check button f12. It should have a small light on it. White means the wifi is turned on, orange means it is turned off. press the button to switch it on and off. The laptop uses the term "Airplane Mode". If this doesn't work you will need to check your WiFi network is listed on the laptop. Go into 'Settings' and go to the 'Network & Internet' settings. Go to the WiFi settings button listed on the left of the screen. You should see your network listed. If you cannot see it listed go to "see available networks" and click your network. It will ask for your security Code to be able to connect.

did you change OS> did change the OS since bought new? no OS stated, why does not one person here say what OS is there.???? its half the system. that. it came new with Linux or windows XP to Windows 8.1 in 32bit and 64bit versions (click control panen, click system) behold the true OS name and version before your eyes. its like saying my FORD died, and no model, gee a Model "A:? here are some facts, most times. dead USB is this. you changed the OS and failed to use the HP driver at HP.com now 1 usb chip works and the other does notl my Elitebook does that, I upgraded to W10 (with zero HP support on purpose) then USB 3 ports went dead, so had to ID the chip its a NEC chip the Intel inside is USB2 only. then the NEC web site had my chip driver. and now those ports work. See how not saying your OS makes help so hard, this is my example. first test the ports only with a test mouse (test all ports now) think small think simple and a mouse is that. does that fail, i can think of 100s of USB devices that will fail hard in w10, all old things why not tell the helper what you plugged in. and be web connected are you.? tell if DM device manager shows any errors at all? did you first use device manager, to see that device fail plugged in? and then right click it and pick update this driver. or did DM shows all USB ports dead.? it just 2 clicks to get there. then it fails, if yes, then MS does not have the driver, we can go to MS right now and prove that. if i get the HARDWARE IDs out of your Device manager page and look in the MS data base i can see if it is supported. case in point old web cams not. old USB wifi dongles not. and more 100s not and 100s yes. that is how it works and goes. now lets got HP.com and look first there, they made it , NOT MS. lets say you said w8.1-64bit OS and i show. https://support.hp.com/us-en/drivers/selfservice/hp-probook-4730s-notebook-pc/5060893 load all the 4 lines of drivers there. there are 3 paths here get the drivers from HP. get them from MS, automatically PnP or manually (ask now manually) get them from the USB chip maker, intel or whomever. if the USB chip really is dead, and the HP driver fails. (I bet not) then get the hardware IDs. tell me that and will fetch them for you easy. its really easy if you know how,and all ways how. if this shows errors , anywhere here, the driver for these chips are wrong.! if you learn how to get the Hardware IDs its 10x more easy.

question #1 did you change the OS from new day 1, for example upgrading to W10? if yes, HP does not support this. forget DELL this has nothing to do at all with DELL ever. Google can't fix machines of any kind, in fact google gets you like 1 million guesses, or lies and all are at best worse than tossing a coin or guessing your self. a fact. It is the Disinformation age, and gets worse every day. what does work, is diagnoses not guessing or reading endless posts by others, most of which lack any facts worth knowing. like yours what OS is there windows what???????? My first guess is the internal speakers are dead. As are $1 earbuds dead.. as the next test. why not tell the helper first, what you are attempting. ? sound tells me zero, tell what you are doing like this. ( one guy cant watch movies online, 2nd cant play a local sound wave file or mp2 and guy 3 cant get windows sounds working. see? DO BASICS first , first walk then run, see? I go to control panel, and click sound then make sure speakers is tuned on here, first. then click SOUNDS. then pick Asterisk, and the test button goes green below. (this works from windows 3 to now) if not green arrow that means the driver is missing. (or corrupted winds or virus infected) if the green botton glow and click it and you hear sounds now then the driver is working. if this test passes, the we go to the next level of complexity the sound player, must work (I use VLC and others) now the driver, at HP, why not ask at HP and not fixya, HP has support for you unstated OS. this exact PC came with Linux or Windows so my guess #1 is windows, sigh. then guess #2 is windows 7 64bit and I land here, in 5 seconds flat. amazing no? the chip is IDT and is problematic https://support.hp.com/us-en/drivers/selfservice/hp-probook-4520s-notebook-pc/4145198 does device manager show errors in the sound chip? if yes and you run w7 , all drivers are above, even for XP and VISTA. only. try posting what PC ,ok you did, the what OS you run, you did not. then tell what you are attempting to do with sound. lots of things do sound ,name one that fails. or all.

try this link might help you out.. Windows 7 wireless connectivity issue wpa psk not available Google Search

what OS? windows, and What windows, XP? HP sold it with 7 different OS, (xp to w7 ./32/64bit) and linux. I cant know what you use for sound at all. the PC has sound chip and 2 speakers and mic., external speakers, or sound buds, what? tell what you have first. 4510s tells little. if you have USB headphones there, it WILL mess up. USB adds a 2nd sound chip set and they clash with onboard set. in fact buying new headphones with USB sound and boom mic built in then going in to device manager and disabling the onboard sound makes the head phones work real well. its not metal bs. sorry. that is jive. i the sound test fails, then it failing that you can be sure. if no bud, or headphones of any kind and only internal speaker ;.mic is used then down load the drivers from HP for you sound is that hard? here https://support.hp.com/us-en/product/HP-ProBook-4510s-Notebook-PC/3934828

Try connecting the tv first... Or getting a new wire.
If those don't work you might want to try the monitor button. Most laptops have them as one of the function keys. Often looks like a projector or a square with some extra lines. Try it with the fn key depressed and also without as fn lock might be on.
But try those first two things first.

1) Go to device manager and uninstall the mousepad / mouse driver, then reboot 2) Go to the HP website and find driver downloads for your probook and download and install the most up to date version of the mouse pad driver. 3) Download and run a BIOS update to bring the system bios up to date. 4) Run malware scan to check for memory hogging malware utilities which can cause such glitches, and remove them.

Is the HP Tools Partition still on the drive? Right click Computer Left click on Manage Let Computer Management load On the left is Disc Management Click on it and on the right information about your local drives that are installed will load. Your C drive should show up and it will list all partitions. Does one of them says HP Tools? Did this problem start after installing the Office software? Does the HP Quicklook pop up come up every time you open Outlook? If so have you gone in to see if its a program that you can uninstall from Add/Remove programs? If you can uninstall it do so. I found this information when searching for hp quicklook HP QuickLook is a Personal Information Manager (PIM) viewer for Microsoft Outlook 2003 and 2007. HP QuickLook caches Email, Calendar, Tasks, and Contact Information from Microsoft Outlook 2003 and 2007 and enables users to view and edit this data quickly from a notebook that is Off or in Hibernation mode (without having to open Microsoft Outlook first). So if you don't need it, uninstall it. It could be causing the issue that you are having.
