Touchpad on/off button not working - probook 4540s

Q: Touchpad on/off button not working - probook 4540s

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.

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)

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.

 

Your computer is one of our business models.

 

Your question maybe better answered on our business forums.

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.

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.

I am just wondering whether I can put a eGPU on my HP Probook 4540s to play some of the more modern games and some of the games that are a few years old now on something like high to ultra graphics. I'm thinking something along the line of a NVIDIA GTX 960 or 970ish. I actually even found some GeForce GTX 1050's at a cheaper price so is there a way I could connect something like that to this laptop. It would be cheaper then trying to save for an actual gaming rig at this time. Thank you for any replies its much appreciated.

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.

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?

I upgraded to Win 10 Pro from Win 7 Pro during the free upgrade period, at the time I had a 500 gig 5400 rpm hard disc, later I replaced the HD with an OCZ Vector 180 ssd, used the included copy of Acronis disc cloning software (i updated the Bios to the newest Version HP offfered prior to installing the ssd), now when I do a cold boot it gives me an error message saying no operating system found, if I go into the BIOS Setup menu then exit out of it without making any changes it goes ahead and boots normally. I can also do a warm boot (restart)it also reboots normally. I tried contacting OCZ support, they had several suggestions such as delaying the startup time 5 secnds, didn't do anything, increased it to 10 seconds with thes  same results (OCZ said the ssd needed more time to initialize itself). After trying 6 or 7 of their suggestions they sent me a new drive, I had saved the original HD so I cloned it to the new ssd, got the same results, no cold boot.  I've tried evey setting I can find in the BIOS, changed it from UEFI to Legacy boot with no results, disabled network booting, everything but Optical Disc, disabled Quick Boot, but nothing has changed. In Legacy mode it shows the internal hard drive to be the first thing to boot from, but that does nothing but say it can't find a bootable drive and then the option left is shut down the computer.

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.
