Just got a new Probook 4540s and cannot get the on/off function of the touchpad to work. There is a small dot in the upper left corner of tochpad. User guide says to double tap it to turn on and off touchpad. Doesn't work. I then went to driver download and got the latest synaptics drivers. Still doesn't work. What am I doing wrong?
I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system
It's worked out well for many of us in the past.
You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)
FIgured it out. I had disabled the "touch to click" function. After I enabled it the touchpad on/off button worked as it should.Read other 2 answers

the touchpad of my 4540s i5 freezes after some time of working.this happens from time to time.i unstalled Synaptics TouchPad Driver and restalled but probles is the same.OS windows 8(64bit)
I understand that your touchpad will freeze.
Do a hard reset.
Turn the computer off.
Remove the power cable and the battery.
Hold down the power button for 15 sec while booth power sources are removed.
This should reset the hardware in the computer.
As you power it back on tap the F2 key. This will load hardware diagnostics.
Run the startup test.
This will test all the hardware in the system and detect any problems.
If the entire test passes, turn off the computer.
As you turn it back on tap the F10 key. This will load BIOS setup utility.
Press F9 to load defaults.
Press F10 to save and exit.
When the computer boots back up, check to see if everything is working.

hello ,the touchpad ,mouse of my laptop is not working from 2 weeks , i use linux(ubuntu 16.04) as operating sysytem .i use external wireless mouse for work .please help.Read other answers
I am unable to use my laptop's touchpad and keyboard. Even my mouse is operational only when the windows is loaded. Meaning, during the booting time when i wish to change the booting option, at that time i am unable to use even my mouse. Which otherwise is the only outside device used via usb port. Earlier there was issue of BIOS application, which was corrupted, which not is visible when i just boot, meaning thereby, the button namely f1 or f8 is operation at the time of booting, but unable to do any change in the booting options which are visible when i just boot my laptop. Though with the help of USB i am able to work on my externally attached keyboard. What should be done to cure this issue this is persistently bothering me for last 15 days. I am unable to make my laptop's touchpad and keyboard operational. 1 thing more only Tab is operational and opening and closing bracket keys work that is it. And as i said now only f1 or f8 works during the booting, nothing else. Please get me out of this trouble. I've trying for many days. But unable to get rid of this issue.Read other answers

Attempted to up-date to Windows 10. Couldn't do it. Microsoft (MS) Tech tried to do it and couldn't do it. It seems there are some security tools that must be removed as they are incompatable with Windows 10. MS tried to remove and couldn't do it. He said they were on the mother board and when he tried to remove them they just kept coming back so once again he couldn't do it. He said contact HP and they could do it. Unable to find anybody at HP that can do it. As you can see nobody can do it so I guess it just cannot be done. That is unless some fine person out there has discovered a way to do it. If thats the case please tell me ho wo do it.Read other answers

Hello,I am having an issue with my Probook 450 g3 running windows 10 pro x64 anniversary update v1607.Most of the time, the audio doesn't work. When its not working, it says that there is no playback device found in control panel --> sounds.I have updated the machine with the latest drivers and bios and it still does not work.However, if I uninstall the synaptics touchpad drivers and reboot, the speakers work fine. Unfortuantely, windows will automatically install a driver for the touchpad and it wants me to restart. The next time I restart, the speakers break again. I have disabled the setting to automatically install drivers in advanced system settings, and it still installs the drivers. Some info:Conexant ISST audio driver version: 184.108.40.206Synaptics ps/2 port touchpad driver version: 220.127.116.11Bios version: 1.14 Please let me know if you need any other details.Thanks,benchRead other answers
Hello! My ProBook 4540s was working fine until a half hour ago, when I unplugged it to move it and then attempted to plug it back in, and it stopped charging. When plugging in the power cord (that came with the ProBook when I bought it around 18 months ago), the light above the power jack (and no other lights) flashes white 9 times. I've tried following this fix I found on Google: 1. Turn off the notebook2. remove the battery3. remove the charging adapter4. press + hold the power button for 40 seconds5. insert the charging adaptor only6. press the power button and it supposedly continues but I get stuck at this point, because even plugged in, my ProBook won't start up without the battery in also. Is this a know problem/is there a fix for this?

HiI tried to update to W10 and failed with OXC 1900200 which suggests a compatibility issue. It is unclear on the HP website if this model supports W10 - HP has not tested your PC model for upgrade to Windows 10.If your Windows 7 or 8 PC was manufactured before August 2013 or is running Windows XP or Windows Vista, HP cannot confirm it can be upgraded to Windows 10. Can anybody offer an advice if the 4540S supports the W10 upgrade and if so any advice on what may be causing the error. ThanksJohnRead other answers

Hi, I ve been using a Probook 4540s from the year 2013. Today while I was reading a book (offline) my display stated to give some unclear pictures. Pictures were moving up and down and gave overlapped scences. Please refer the attached GIF or click here to understand the scenario (Link to GIF https://giphy.com/gifs/QzGO4cPW76wUM ) I updated the Intel Video Driver also but it could not solve the issue. Then I restarted the computer. During the boot process I realized it is not a software issue as the dispaly was acting the same. I feel this is like a hardware issue in the display or the ribbon cable.Please look at this and help me solve the case. Highly appreciate your coordiantion on this.

I found that my Probook 4540s sometimes cannot boot. I have to use the trick applied to 4530s: remove battery, press power button for 40s, put the adapter. Sometimes the trick works, sometimes it doesn't. Is this a bios issue? Any solution for this?
Well did you try reseating the memory? Has the computer worked since you have upgraded the memory? Also are the memory chips the same speed? If your running two different speed chips it could cause this issue. ThanksSeanRead other 10 answers
I have a new ProBook 4540s notebook that I shut down over the weekend. I am not sure if I put it into hibernate, sleep, or what as I am still getting use to it. When I tried to turn it on (not plugged in) I got nothing. So I plugged in the power cord and hit the power button again. All it did was the LED above the cord plug blinked about 8 times and nothing else. I let it "charge" overnight and tried again in the morning. Nothing but a blinking LED. I Googled the problem and it said to take the battery out, unplug, and hold the power button down for 20 seconds. I plugged it back in but left the battery out, and still the same thing - flashing LED. HELP! Thanks.
Hey SBProBook,Do any other LEDs blink? Take a look at this document and let us know if you see any matches to these patterns:http://support.hp.com/us-en/document/c01443366

My laptop is running Windows 10 64-bit.
For the past few weeks my laptop has been turning off unexpectedly.
I've tried with battery only. With battery and power cable and with battery removed and only power cable.
I am using the machine normally and then screen just goes black and power offs - no restart, no hibernation, no shut down. Just instantaneously off.
It's not overheating. Could it be a fan issue?
I don't know - but it's getting quite irritating as I often have many apps open and many files open on each app and takes me 30 mins to get back to where I left off.
Is this the same problem as the thread you have posted or is it a different one.

I bought my laptop about two weeks ago. Then first, I installed Windows 7 Professional 64 bit. I installed "HP Protect Tools" & could enroll all 20 fingers at once without any issue. Then recently, reinstalled the whole system with Windows 7 Ultimate 64 bit. Then, installed Protect tools & could enroll my two thumbs. But I couldn't enroll any other finger. For each other finger, first two confirmtions work properly. But at third, it always fails. I cannot think that this is an issue related to how I sweep the fingers. Because, then how do every first two confirmations get passed?. Hope anyone will help me to sort this out.

Given HP's recent corporate reorganization, hp.com may never be updated.

Hi, I've got a secondhand Probook 4540s from a shop near me which sells used laptops. At the time i got it it came with Windows 7 Professional 64bit. Everything was working smoothly, then I started updating the graphics card drivers and other drivers in it (in hopes of improving perfomance) and it was around that time that windows started complaining that this version of windows is not genuine. (I think it was after i updated bios or something. or I used a non microsoft software to download microsoft updates because my microsoft update manager was not working) So to the problem at hand now. I want to format my pc and for that I need windows product key right? I cant find it! It is not in the back of my laptop, not under the battery (The battery is seemed to be replaced) and I did not get any installation media along with the laptop. Any idea how to get my windows product key? or do I even need one to install windows in this laptop (like win8)I dont think the people at the shop can help me on this.
