Hi MeroYasso, To get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial product. You can do this at Commercial Forums. You could do a system restore. It would reset the update that has caused issues.Thanks.

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?

Intel chipset drivers are not available for Windows 8 or 8.1 on hp.com (Intel ME drivers are available in their place, some kind of inside joke, I guess). Given HP's recent corporate reorganization, hp.com may never be updated. I think only an HP insider could answer these questions: 1) Did HP modify the Intel chipset drivers as OEMs often do or could I use ones from Intel? 2) Is there any difference between Windows 7 and Windows 8/8.1 chipset drivers?

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. (Also,  the Probook 4540s does ship with windows installed right?)

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.

Hello, Neither my windows, nor any apps (like Skype, e.g.) can detect my built-in webcam. Pre-history: I upgraded from win 7 to win 10, installed skype but found skype can't see my webcam. Then I looked in the device manager - there was no imaging devices at all. I then downloaded and installed the webcam driver (HP Webcam Software (International), SP52437) from HP website and hooray - the webcam started to work (skype could see it) and I could take images. The next day after win 10 update the webcam stopped working again. Itried to re-nstall the same driver (SP52437) but during installation it said "Setup has determined that your configuration does not support any of the included products" I found on the web that lots of people who upgraded to win 10 having issues with their built-in webcam not working. So I rolled back to win 7 but the camera isn't working again! In my control panel I do see Imaging devices and a driver 'USB2.0 UVC 1M HD WebCam' with a yellow exclamation mark, but when I try to update the driver the system fails to find a newer version and the exclamation mark remains. I also tried installing another generic driver for HP website - 'HP universal camera driver" (SP47460), but to no avail. I spent a week searching web for solution but couldn't find one that would work. Please help me to make my webcam work! Thank you very much!!!

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.

A:the touchpad of probook 4540s i5 freezes after sometime

Hello zamsam,

 

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.

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.
