I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Dear Customer, Welcome to HP Support Forum and we are glad to assist you. This is to inform you that all HP Business Notebooks such as Probooks or Elitebooks have more stringent security than consumer models infact they don't produce 'halt codes', the password cannot be derived from the Serial Number and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case. Please have a look at this link. http://forums.mydigitallife.info/threads/49497-HP-Probook-Elitebook-BIOS-Password-Reset-Utility 2. Please Contact HP Business Notebook support they should be able to send you a customized SMC.bin file which you can use at boot to reset the password. Hope this helps, for any further queries reply to the post and feel free to join us again **Click the White Thumbs Up Button on the right to say Thanks**Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem.

I just have a quick question that i have not been able to find online anywhere and am wondering if you can provide some resolution for me. When I access the BIOS by clicking the F10 key on my laptop when I boot it I get the below environment which seems to be what everyone gets Now my question is if there is anyway to access a more "user friendly" BIOS layout like every other laptop/computer has shown below. I find that I don't have access to every option on my laptop in the BIOS that is currently present and I have the F60 BIOS which is the most recent one but most things are grayed out and I can't change things like the RAM speed or anything like that so I feel like I actually have no control over my system

Ok let me explain the situation. I have one main pc and one laptop. Both with win7. I originally had both of them setup in homegroup and it worked well. But today, because of my curious nature, i tried to change about some settings.

I removed myself from the homegroup. Then when i try to click on my main pc's name under network it asked for a username and password. I entered the user and password for for a certain user on the main pc (and foolishly clicked to remember forever), and now im in the network no problem. But the issue is now that i can access the personal documents of another user on that same pc! Previously when i was on homegroup i had it set up to only share the printer and i couldnt see any other docs.

When i join the homegroup now and set it up to only share printer i can still access all the other docs.

So how do i get it back to how it was? Im really stumped by this. Also windows credentials doesnt store the password either, only the homegroup one.

A:Bizarre situation.. i want windows 2 forget my pasword.

ok no worries

i fixed it by forcing windows to forget all my passwords with this command in the command prompt

net use * /d /y

pheww!

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.

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.

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 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.

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.

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.

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.

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?

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?

FIgured it out.  I had disabled the "touch to click" function.  After I enabled it the touchpad on/off button worked as it should.

I am using my HP ProBook for past 3 years. When i tried to access my laptop i'm getting this error message- "bootDevice not found(3F0)".But i have a pre installed OS on my harddrive. I read few solutions on the internet but it didn't help. When i tried to access my BIOS , it was asking for a password (Which i dont remember setting up one). Now , i dont know the BIOS password and i cant access my laptop. There are a lot of important stuffs in it. So i can't simply get a new harddrive. Please help! Thank you.
