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...

View 1 Replies View RelatedI 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".
I have a Dell Studio Laptop, Model PP39LThe laptop has a fully charged battery and is plugged in. The Led on the battery plug (going into the computer) lights blue.When I press the power button the screen will flash white for a second and then nothing (no beeps either). The little white led on the computer by the power jack will light up white for a second and then turn off as well.This has happened in the past but it just worked after leaving it alone for a few hours.
I haven't turned the laptop off since this incident. I've been putting it in stand by/ sleep mode and everything was fine. I was also able to restart the computer with no problems. It's just when I power down when this happens.The keyboard recently froze (new issue) and I had no choice but to reboot by powering down. Now it won't turn on. I have never spilled anything on the laptop. Nor have I dropped it or caused any other damage to it. I'm thinking it might be a problem with the motherboard.
This is my 3rd day since i bought this new HP probook 4540s [Product No. B9A39PA#UUF] and i like it, i made a clean install for windows 7 ultimate x64 and i've just realised that the hp drivers support page dose not has any drivers for the ultimate version, so i downloaded the proffesional drivers, now i have all devices are installed except two devices named unknown device
The hardware Ids:
1- unknown device
USBVID_138A&PID_003D&REV_0104USBVID_138A&PID_003D
2- unknown device
ACPIHPQ6000*HPQ6000
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 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 currently have a HP ProBook 4540s Notebook PC(Energy Star) laptop and found that my Base System Device Drivers are missing. I have been trying very hard to find them but to no avail.

View 5 Replies View RelatedI 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'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.

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 bought this Envy 17 3D in December of 2010 from HP Websight. The Model is WY771AV and runs Windows 7 with 1080P and Uses A M D 5875 Graphics. The Last 30 days, @ boot-up, the screen will turn solid white when I try to start it up. All I can do is hold power button down to power off and retry. 9 0 % of time, retry fails(does same thing), but occasionally I can go to startup repair , run system restore and use machine for 2 or 3 times before the next white-out.
View 2 Replies View RelatedMy 5 and half year old Dell 600m is facing its biggest problem right now, and it has had many problems over the year..
Last week, I put the computer into safe mode to scan for viruses, and left it for an hour before logging in. When I came to log in, the computer screen is all scrambled..
I thought it could be a temporary problem or it may be overheating, so I restarted it a while later. However, the screen is still scrambled. Here is what it looks like..
For last one month I am facing this issue, the white display in the lcd screen. This is not happening very regularly, it happens intermittently.
I need to forcefully shut down the machine, after restart sometimes the problem goes away, sometimes it stays. I shut down the machine in that case.
What is the reason behind this and what is the resolution to fix this?
I recently have had a problem with my Dell XPS M1530. The laptop crashed from what I presume was it overheating. When I switch it back on the screen lights up white with no display. I am able to use the laptop through an external display (pressing FN F8) however the quality is very poor, this is surprising as I used to use an external display frequently at a high quality and I am now unable to change the screen resolution in the display settings. I have also noticed that I can no longed put the laptop into 'sleep' mode. How the two errors could be related but both happened after the same crash.
I have tried to recconect the video cable but unfortunately it didn't work.
Any simple fix to this problem or if the GPU or screen needs to be replaced?
I have an HP PAVILION G6-1241EA and I just got a new motherboard and I installed it into my laptop. My laptop turns on but the screen is white. I looked at the wire and it is fine and I tried plugging in some other monitors vga and hdmi but nothing happens. Its been a long time since I've been on the laptop.
View 1 Replies View RelatedMy screen recently started getting a lot of faded white lines going horizontal and vertical across my screen causing the screen to blur/disorientated my screen. I can still navigate just fine but there is clearly something wrong here. I've plugged it into my hdmi's port on my tv and the image is just fine. Is it a wiring problem maybe? The lines are getting slightly more extreme and a little more colored... They lines of windows extend around the border all the way to the end if the screen.

View 2 Replies View RelatedI have a Compaq 3000 Laptop, it's almost 2.4 Years old now, over the period of time I dint faced any issues with my Machine.it all started yesterday.
I was watching a movie on my Laptop yesterday, after sometime the screen froze up but the movie was playing as I was able to hear whats going in the movie.
Later I tried restarting the machine, what i get is the machine boots up properly, but the screen doesnt display anything thing, it shows up a blank white screen, sometime when the windows XP loading picture comes up the screen shows light distorted colors but again goes white blank.
I did approached a local vendor for that but he says that we need to replace on the motherboard, I was not much convinced over his explanation over the issue.
I would like to know your views on what might be the problem with my Machine.
I am going to try over connecting an external monitor and see if LCD is the problem, but I would like to know more what all possible options are there which might be affecting my machine and how much would it cost me in the worst possible case.
