HP Probook 4540s - Windows 8.1 - Battery issues - Closing unexpectedly

Hello,
I have a 1 year old HP Probook 4540s that recently has the following problem.
When unplugged the laptop suddenly shuts down even tough the battery shows 29% still remaining.
I receive no notification from Windows or anything, it just shut downs like when the battery reaches 0%.
Then in order to start it again, I need to plug it in.
Is this a known issue ? I previously didn't have any battery problems and running the HP Assistant informs me that the battery is ok and it doesn't need replacemants.
Any idea how to fix this issue ? Basically the laptop is dead at 28%-29% battery life.
Thanks.
This question was solved.

Processor hangs after adding more RAM to probook 4540s

hey ALL
recently i upgraded my laptop hp probook 4540s to 16 GB RAM
I am having two identical (Same part numbers) RAM sticks of following specs:
manufaturer: TRANSCEND
Memory : 8 GB (each)
Frequecy : 1600 MHz
Type : DDR3
PC3 : 12800
the issue is the lowness of processor. Processor utilization meter shows 70 to 80 % utilization with these two sticks running.
If i install only single module of 8 GB then the System runs great. i have checked both modules individualy by installing each of them in single channel configuration. also i changed the slots in single channel configuration. in single channel configuration everything runs great.
the complete specs of my system are :-
Specifications
do anyone have any idea of what is going on
i shall be very thankfull to everyone for helping me on this

Hi,
According to the Maintenence & Service guide for your notebook a maximum of 8GB is supported in your notebook.
The modules supported are PC3-10600, 1333-MHz, DDR3. They are not PC3 12800 modules like the ones you have installed.
That would seem to explain the issue you are having.
Best regards,
erico.

HP Probook 4540s upgrading RAM

Hi,
I would like to upgrade my memory (4GBs are not enough in theese days) for probook 4540s
Now, I have 1 module with theese specifications:
CPU-Z:
DIMM #               1
   SMBus address       0x52
   Memory type       DDR3
   Module format       SO-DIMM
   Manufacturer (ID)   Hyundai Electronics (AD000000000000000000)
   Size           4096 MBytes
   Max bandwidth       PC3-12800 (800 MHz)
   Part number       HMT351S6CFR8C-PB
   Serial number   (Personal information removed)
   Manufacturing date   Week 38/Year 12
   Number of banks       8
   Nominal Voltage       1.50 Volts
Question is:
Can I add newer model to the second slot?
I want to buy:
HP SO-DIMM 4GB DDR3 1600 MHz Unbuffered
Certificated for PC3-12800 (B4U39AA)
It seems, the new model of ram module should be compatible with my notebook, but will be compatible with my old module, while working on 2x higher frequency?
Or I have to buy 2 new modules and replace the old too?
Or I missed something and it is not compatible in any way?
Also, I have red at other forums, that upgrading memory up to supported 16GB takes some performance issues. Is it still ture, or is this already fixed?
Thanks for answer

Hi ,
The model supports the following specification of memory.
Standard
DDR3 PC3-10600 SDRAM (1333 MHz)
Two SODIMM slots supporting dual-channel memory.
2GB and 4GB SODIMMs
Maximum
Upgradeable to 8192MB with optional 4096MB SODIMMs in slots 1 and 2.
Dual-channel
Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots.

Probook 4540s HHD randomly gets very slow

Hey, I have hp probook 4540s running windows 7 ultimate 64bit.
Problem is HDD sometimes (after startup) being very slow, transfer speeds according to resource monitor are ~200kb/s, windows startup takes around 30minutes. HDD transfer speeds do not get better no much how long u wait.Cpu and memory usages are regular (=low) while this happens.All diagnostic programs (hp ones) do not find any issues.
First I assumed it being a virus or windows problem so I formatted HDD and re-installed win7, a few days went by and it happened again. Computer has latest bios, and drivers, except update sp59047.exe which should be firmware for hdd this computer has. Running this sp59047 opens window which says hdd is correct for this update.. then it restarts computer which ends up in ms-dos looking command prompt saying failure. This environment has autoexec.bat and auto2.bat which both return 'failure' while i try to run them.
HDD itself cant be seen but it has sticker 'replace with hp spare 641672-001 and 8k12a0. I'd expect software issue but this is fresh windows 7 with only regular stuff (firefox, adobe flash, .Net, directx, teamviewer, and kaspersky antivirus).. when problem first time appeared this computer didn't have any antivirus, so likely kaspersky isn't causing it. So, ideas what might be the problem? Lack of that firmware update? HDD about to fail? Computer still has warranty for 2 weeks, but I hate dealing with dealers when problem is something like this which passes build in-tests and happens randomly. Haven't tried with HP yet thou.

HP Probook 4540s: Fingerprint Scanner Not Working

Hi,
Problem: Fingerprint Scanner - Windows log in does not give option to log in via fingerprint scanner.
Overview: After installing fingerprint drivers from the HP site and using the HP Protect Tools to successfully enroll fingerprint, I tried logging in via this method but the windows log in screen does not display this option. Device manager correctly identifies and shows the fingerprint sensor - however, the control panel says no biometric devices detected.
I really need help in sorting out this issue. Details of what steps I took trying to make the scanner work are given below.
Specs:
1) Probook 4540s
2) Windows 7 64-bit
3) i5-3210m, 1Gb Hd 7650m, 4 Gb 1333Mhz, 750Gb 5400rpm, VFS 491 Fingerprint scanner.
Details of the problem and steps I took to install drivers:
After a fresh installation of Windows 7, I went to the HP driver site to download the latest drivers for Probook 4540s:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=5229457&...
I installed the drivers in roughly this order:
1)realtek ethernet controller drivers,
2)audio drivers,
3) the chipset and USB 3.0 drivers (but not the Intel MEI driver)
4) Intel video driver: faced an issue such that drivers were not being allowed to install. After disabling switchable graphics in the bios, I was able to get these drivers to install.
5) AMD video drivers: installed after the intel HD graphics driver - installed but Catalyst Control Center was not being displayed. So I re-enabled switchable graphics in BIOS, re-installed these drivers and CCC was now available.
6) HP hotkey support
7) HP universal camera driver
8) Validity Fingerprint sensor
9) Synaptics Touchpad driver
10) Atheros wifi & bluetooth
11) Jmicron card reader
After driver installation, I installed the HP Protect Tools. After prompting for a PC reboot - which I did - it asked for setup of security etc.. Part of this pocess was the enrolling of my fingerprints - successful. However, upon log off/ restart of windows, an option to log in with the fingerprint scanner did not appear in the Windows log in screen.
I opened the Control Panel, and found there was no biometric devices tab, even though device manager showed biometric device and validity sensor (VFS 491). I then proceeded to uninstall HP protect tools and the validity driver for the fingerprint sensor, then made sure these services were running:
-Credential Manager
-Remote Procedure Call (RPC)
-DCOM Server Process Launcher
-RPC Endpoint Mapper
-Windows Biometric Service
-Plug and Play
Then as suggested in another forum post, I first installed this :http://ftp.hp.com/pub/softpaq/sp55001-55500/sp55109.exe and then the validity drivers from 4540s drivers page, and then HP Protect Tools.
After reboot HP Protect Tools as before would enroll my fingerprints, but again no prompt at windows login came to log in with fingerprint. However, one change after the installtion of http://ftp.hp.com/pub/softpaq/sp55001-55500/sp55109.exe was that in control panel there is now a tab for biometric devices; however, it says that windows did not find any biometric devices installed. An image is attached showing both the device manager and the control panel!
Please HP provide a solution. Thanks!
This question was solved.
View Solution.

Ok problem solved. I dont know whether it is related to the installation of HP windows 7 Essential System Updates and Intel MEI driver or not - but I did install these.
What really worked without doubt was this - > install both the fingerprint drivers and then the HP Protect Tools. Once rebooted, open HP Protect tools, then go to administration in the bottom right corner -> Administrative Console ->Increase System security -> tick windows login security and your done. Now you will be able to log in via enrolled fingerprints.

Probook 4540s view rotates (almost) randomly. Please help

Hi, this is a Probook4540s. I have recently updated to Windows 8.1. The view on the display started rotating upside down when I lean the laptop backwards and forwards, when I click buttons on the toolbar and sometimes when I click the close / minimize buttoms.
I can rotate the view to the normal view by leaning the laptop forwards or by clicking alt gr + upper arrow (only if the keyboard is in Romanian. It's very frustrating, since I hold the laptop on my la and make slight mooves.
How do I make it stop?
any suggestions will be appreciated.
Many thanks!

HP ProBook 4540s slow to boot up, all programs run slow, long delay, show non-responding messages

Hello,
I have a HP ProBook 4540s running windows 7 (desktop shows: Test Mode Windows 7 build 7601)
The HDD is a Toshiba mk5061gsyn 500gb
For the last month or so the computer has been running very slow. The computer has always booted/start windows a bit slowly. Now it takes about 3-5minutes to get to the welcome screen then it takes a couple of minutes to load windows. Soluto shows all the programs that are being loaded on startup. (I never messed with this). I've run several antivirus programs and the system is clean. Back in June I had the same problem but there was malware found, not this time.
I ran speccy and it shows "warning" under the S.M.A.R.T section. I used the HP system tools and ran the HDD test and no errors were found. When I tried using the HDD test from Toshiba and I couldn't run the scan test, it only showed the model name and serial #.
I'm not sure what to do next?
Thanks for your help in advance!

HP ProBook 4540s USB 3.0 Driver

Good evening! I am having an issue with my USB 3.0 drivers for my HP ProBook 4540s. I had done my own research on the problem and came across another forum post (http://h30434.www3.hp.com/t5/Hardware-Upgrades-Replacements/ProBook-4540s-USB-3-0-drivers/td-p/32518... and had tried to install that driver. I have tried the driver in the past as I believe it to be the problem that I am having and it comes up with, "This computer does not meet the minimum requirements for installing the software." everytime i try to install. The issue that i am having is that no device I put in my 3.0 ports is recognized by windows and it does not display them under Computer. Have tried keyboard and mouse in the ports as well with nothing but power. Any suggestions will help. I KNOW I need to replace my motherboard but that is for a battery problem that HP gave me the runaround with until my warranty expired and now is refusing to help. (I have been working with HP to resolve my motherboard issue for over a year now and am STILL getting the runaround from everyone I talk to) PLEASE HELP with USB.

Thanks for the reply so fast! I am getting the same error when trying to install. I will attach screenshots.

HP Probook 4540s Moving horizontal lines

I haven't had this lovely laptop for more than a year and I have only one issue with it. Whenever I am in something that is full screen and I ALT+TAB out of it, these lines appear. They are horizontal and move up and down, distorting the screen for about 30 seconds, making it nearly impossible to see anything in the background. I tried installing the new graphics drivers and BIOS driver, but I cannot think of anything more myself.

CPU upgrade for HP Probook 4540s

Hi Support Forums!,
I have recently purchased an HP Probook 4540s (Energy Star gen 3 i5 2410m 2.5 Ghz) notebook.
Does this model have a socket cpu, which would allow the cpu to be upgraded later?
If so, what i7 cpu types/models can it be upgraded to?
Cheers
