this? lint from dog hair cats ,rugs, even at 1 year old. lint is endless. then it taps dust, and dead bugs and like and is nasty as seen below. blocks he copper rad super bad that. enjoy the view. s

do not do that. TPM is one way trip if it locks you out, the PC is bricked forever. why use TPM its for CIA/NSA/DOD/DOJ, etc. why? and the chip must bet there and on old PCs it is not. here is your answer from HP. https://h30434.www3.hp.com/t5/Notebooks-Archive-Read-Only/TPM-and-an-HP-ProBook-4540s/td-p/2349199 THE ANSWER IS NO, HERE IS NO TPM CHIP THERE. SO THAT IS DEAD.

why is there a monitor (external) on a Laptop. I guess the laptop LCD died too? no monitor told, makers name and brand or are you calling the lock LCD screen a monitor, well it is not. most old monitors died now, 2010 and older, non told they all die or 1/2 screen dead, from 1/2 the CCFL back lamps are Dead or dim or yellow tinged, or blink or fully intermittant the cur for the monitor, if is one, is test it on a 2nd PC. bingo good/bad known. if not a monitor here same answer. CCFL die in PCs old and monitors. CCFL are cold cathode fluorescent lamps. no PC told no photos of bad screens. sad face.

on ONE PC or all and TV? answering for ALL PC fail. your router not told read the manual on our unstated router . then using (a it told you) a browser on the PC go to 192.x.y.z address, (it tells you) and set DNS to 1.1.1.1 save exit router service page. see it works./ the router has a name , 15 makers? and zillions of models all are not the same but all have a DNS page, ever one,(for 20 years)

it is a one w3y trip,TPM and if you mess up boom bricked for ever. are you with CIA, only CIA,DOD.NSA ,DOJ use this the BIOS pages if looked snow this is there or not hp.com read your manual, 4440s the OS must support it too, none told at all. I say avoid it like the Plague, unless working for the MOB?(grin)

its broken buy a used or new switch assy, on ebay.

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.

push volume up key.?

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.

RTM? yet (if you had, it be NO)https://support.hp.com/us-en/product/hp-probook-4540s-notebook-pc/5229455/manuals

jackers day:learn that probooks and hp elitebooks are both enterprise grade PCs that means the PW storage is fully 100% secure.besides guessing it.ok. it not stored in NVRAM, ok? it in 1 of 2 placesa custom EPROM or the TPM chip or both.only they can fix it, HP. nobody else.I will not tell about hackers, ok?, risking bricking you PC for ever.admin BIOS password loston mine you can have 3 levels set.1: BIOS PW , admin or users, admin can fix users ok?2: FINGERPRINT.3 :AND THE CUTE INTEL BACK DOOR THING.What is that,? well RTM your manual covers that.all that magic, but the intel (if turned on) you get to guess 3 questions. if right bingo. you be in,, but I bet 2 and 3 are off.that is what you paid for... and not cheap.again ask at hp.com the most complex URL on earth, huh?

hyjackers Hemahema1281 wants more answers to this question 6 year old posts. jacked, to 2019 why no ask HP.com this on THEIR FORUM the PROBOOKS are enterprise grade, PC and are not allowed to be hacked easy like toy grade PC's are. (no magic hidden jumpers, no back door passwords) These passbooks have special chip that stores the PW or TPM chip, you will never hack that. The PW is not in the NVRAM like on toy computers. old. so the coin cell trick will not work do you see why, answer, the PW is NOT THERE. but why even ask here, and not here, , I will now take you to the correct place and exact same topic (wow no?) ProBook 6470b here is your answer, and official, the smc.bin file fash the chip file, that only works on YOUR SERIALized PC and nobody elses. BY DESIGN not by accident. https://h30434.www3.hp.com/t5/Business-Notebooks/Bios-reset-HP-Probook-6470b/m-p/6766426#M151577 if stubborn ask them your self, and get hammered with facts.

You'll probably have to replace it. There are videos on youtube that can give you instructions on how to replace it, or you can bring it into a qualified computer repair shop and they can replace it for you.

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.

Hello, can you be more precise and best describe your problem ? Maybe add a screenshot. Thanks, Antoine Viallon
