HP ProBook 4540s , bootDevice not found problem

Q: HP ProBook 4540s , bootDevice not found problem

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.

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 support team,  since I upgraded my notebook's operative system to win10/64 bits I can not use a HP v210w 64GB pendrive. The displayed error in the "connected devices" tab, at configuration control panel is "Error de Controlador" (driver error, in spanish). I tried the pen in other notebook, that uses win7-64 bits, being possible to access.  Would you, please, help me? Thanks in advance. Regards,Jorge V

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.

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. Thanks,Isuru Reference Image

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. ThanksJohn

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?

A:bootdevice no found

Hello aartvisuals, Are you able to enter in the BIOS while booting? If you are able to load the Boot menu in the BIOS, you have to check whether you can see the hard drive listed in the available options for boot. If the hard drive is not set in the first place to boot from, you have to manually adjust this setting and select the HDD. Save the changes and restart the laptop. Does it make any difference?  Hope I gave you an idea. Happy weekend!

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.

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 have a problem with my laptop which cannot reboot properly. When I restart windows, i get message saying boot device not found - Error 3F0, then (after few seconds and cominicates) I need to press any key, it restarts again showing white screen with options (eg. diagnostics, system information etc.) so I press Esc and system boots properly! It happens almost every time. It happens only on reboot - when i shutdown my laptop (by windows or by power button) it starts normally. I did some testing and found out it's related to SATA3 option in bios - it looks like it only happens when I set SATA to 6GB/s mode (i can choose 3GB / 6 GB option). I just replaced my hdd to ssd drive, so I need 6GB/s mode to fully utilize new disk. I upgraded BIOS to latest version (68SCF Ver. F.63). When I switch back to 3GB/s mode problem dissapears, but then I have max 250 Mb/s read instead 500 Mb/s. Could this be a a BIOS issue or maybe mainboard is somehow broken?

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?

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.

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 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.













Solved!
