HP ProBook 4540s :: Windows 8.1 - When Unplugged Laptop Suddenly Shuts Down
Aug 28, 2014
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.
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 replacements. Basically the laptop is dead at 28%-29% battery life.

I just purchased a new probook 4540s core i5 with win7 x64 system.
Firstly, When battery full charged then turned laptop off for a few hours or next day it becomes 99% or 98% although its plugged in Ac power. Shutdown again for 1 hour and turn on it turns to 97%. Is that ok or there is problem in battery specially it shows that ( Plugged in, Not chareged ) so laptop should operate at AC adapter and battery remain 100%. Secondly, I have an unknown device can't find it as shown in figure below.

I recently purchased a ProBook 4540S C6Z35UT notebook computer. I love the hardware. It came with Windows 8 64-bit. I never tried Windows 8 before, but I've used Windows 7 a lot. After playing with it quite a bit, I've decided I really don't like Windows 8 at all. The Start screen just gets in the way. I want a standard desktop where I can plop down some common docs I'm referencing, common program icons, etc. The flipping to the neo-Win7 desktop that Windows 8 does is quite lame. If you run a desktop program from the start menu, you flip to the desktop, but then it stays there after that program exits. It's a very "hack" design. The start menu is cute for touch pads ("surface"s) but not really laptop/desktop appropriate, imho.
So my question is: if I purchase a Windows 7 or Windows 7 Pro 64-bit version of Windows, can I install it on this machine and will it have the right driver support? Also, in case something gets messed up, is there a way to create a Windows 8 install DVD for my laptop to get it back to original state?

I'm trying to migrate my HP from the hard-drive to a new ssd I bought. As far as I know windows 8 is supposed to activate based on the code burned into the machines bios, so I bought some hp recovery dvds online as HP recovery manager no longer seems to ship with these machines, so I couldn't make one, and reinstalled windows 8 onto the machine. After install and connecting to the internet the activation failed, it said the key was blocked. This can't be, this machine came with windows 8 preinstalled, so it must have a valid key and license I've already paid for.
I've tried burning reinstall media using the Microsoft media creation tool but that too fails once it connects to the internet to validate the activation
I would prefer to fresh reinstall, I'm not even sure the drive I took out works anymore or isn't altered at this point, plus its larger than my ssd so cloning would be a problem. And I've also read of problems cloning windows 8 secure boot installs regardless. In any case I would like to some how be able to get this recovery to work.

When I unplug it, the laptop immediately shuts off.
The battery also only charges up to 92% and doesn't go any higher.
Does this mean my battery is faulty and needs to be replaced?

I have a HP Probook 4540s Notebook PC. I reinstalled the operating system (Windows 7 Ultimate) recently and installed all the necessary drivers required for the PC. But now as I connect a USB 3.0 hard disk into the USB 3.0 ports ( the left two ports), i get an error message. The message is shown below:
"Device can perform faster : This USB Mass Storage Device can transfer information faster if it is connected to a Super-Speed USB 3.0 Port"
The speed of the data transfer also seems to be very low, in the ranges of 20-30 Mbps.
I'm not sure if I have installed the correct driver for the hardware. As for now, as shown in the Control Panel, I have installed "Intel USB 3.0 Extensible Host Controller Driver".

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.
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:
[URL]
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
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 [URL] 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!

I was watching a movie on Netflix, and all of the sudden the screen kept scrambling itself. I shut it down and now when I restart my laptop all I get is a white scrambled screen. I restarted it again and now I still can't do anything and it won't shut down unless I hold down the power button for a few seconds...

My inspiron 15r 5520 is 1 year old and now it shuts down suddenly when doing slightly stressful tasks like playing games ,which i didn't encounter in the starting months.
But from week whenever i play a game it shuts down in 10 min .Later i tried few suggestions from dell forums on overheating and found that the laptop runs fine on battery and as soon i plug in the adapter it turns off in 10 min .I checked if it is a overheating problem and found the cores temp at around 60 degrees celsius when idle and it crosses 100 when i play games plugged in and around 95 degrees on battery.
I then checked if its due to dust but everything is clean and i use a cooling pad so this is quite abnormal.
I have all the updated drivers and bios, fresh installed windows again, so what to do...

Whenever I unplug my laptop from external power, the screen considerably dims and the taskbar turns white over it's usual blueish black. I've gone into the power settings and changed them so that brightness is 100% when unplugged, but to no avail. According to my computer it's at maximum brightness when unplugged but it's obviously not. Trying to increase the brightness by the sun key or pressing Fn up doesn't work either. Tried to go into BIOS via F2 but couldn't find a video or brightness option.

my Inspiron 17R no longer recognizes when it is unplugged from the AC adapter. This means that when you check the power icon it always claims to be connected, even if it's not, and that the charge meter basically can't be trusted (it'll say it's fully charged when it's not). It also means that it fails to adhere to its power plans because it never goes into battery-only mode. I have contacted my local Dell tech support, but after checking my bios and seeing that my computer recognizes the AC adapter, they didn't know what to do. how to get my laptop to properly recognize when it is and isn't plugged into the power supply?

I have an Aspire 1694wlmi with a 2GHz Pentium M, a Mobility Radeon x700 (256mb) and 1GB of ram. I run Win XP with SP3. I didn't do anything to the comp apart from removing its crappy built-in wlan adapter.
The issue is this: whenever I play any game (even as undemanding as UT99) the laptop just shuts down without warning. This even happens playing 8ballclub's billiards sim in window mode for instance.
The whole thing started happening occasionally a long time ago (with Rome Total War at first). Right now, it happens always and very very soon after starting the game (i.e. less than a minute).
I have noticed that the CPU usage jumps to 100% as soon as I launch the game and stays there until shutdown (but this is supposed to be normal, yes?). Also, I tried stopping all non-essential processes (of which there weren't that many to begin with) and the CPU usage is around 0-4% when idle.
I have also opened the lid and look for dust - none there (neither around the processor nor around the graphics adapter)
I tried updating the ATI drivers, but since the Radeon is included in all Acers, it won't let you update the drivers - and Acer doesn't provide updates either. I have installed the Catalyst Control Center...
People have associated such problems with viruses. I use Avast which finds no viruses (I'm installing Kaspersky next).

I updated the bios which fixed other issues. I updated the drivers and did all the win7 updates to rule any of that out. When teh laptop gets down to 18% it just powers off instantly. It does not go through a normal shutdown process or hibernate. I can power it back on and it shows 18% battery left. Is the battery going bad? I dont think this machine is barely a year old yet. I have no problems on wall power. Could it be a Win7 power setting? Just surprised win7 would slam the power off like that.
