HP Elite L2201X - no video in BIOS

Hi all... I'll start with the plug.

1 = HP Elite L2201X monitor

Monitor 2 = LG L226WT - BF Flatron

Video card = EVGA GTX 570 HD (with Display port)

PC specs = Intel Pentium Core 2 Extreme (4 GB RAM)

OS = Windows 7 Ultimate 64-bit - AND - Linux Mint 10

Problem = using only the HP Elite L2201X plugged into the video using the manufacturer card display Port Display Port that shipped with the HP Elite monitor cable... There is no video when the PC is started.  You can not see the BIOS or Boot Menu GRUB from Linux.

Attempt 1 = testing various adapters and cables (DP to HDMI, DP to DVI - D and another DP to DP cable).

Result = no video

Attempt 2 = Hot-Plugged DP DP in the my work (Lenovo W510 with Display port) during execution of Windows 7 PC.

Result = HP monitor turned on and cloned the Windows desktop.  I know the monitor and delivered the work of DP cable.

Try 3 a = HP plugged into main PC using DP to DP.  LG monitor plugged DVI - D.

Result = BIOS appears ONLY on the LG DVI - D monitor.  White screen on HP (light orange sleep all the time).

Try 3 b = LG monitor to help, on the start screen for Linux, continued to load Windows 7 with two connected monitors.

Result = finally turned on HP and took control, as monitor 1 in Windows.  LG became the 2nd display Windows.  Once again, this proves the monitor and delivered the cable work of DP on this PC as well.

Then... the question is... I don't have 2 monitors on this PC.  Remove the LG monitor and leave only the HP Elite... I never see the BIOS or the Linux boot menu (this isn't a driver problem because it is before all the OS loading).  So, how to solve this problem?

Just to add... I bought the graphics card EVGA GTX 570 HD ONLY because of this monitor needing a Display Port adapter.  I had already tried and has invested in the DP to HDMI and DP to DVI - D adapters and they do not work on the old card.  Since then, he has worked directly with my laptop to work, because he had a display Port so no adapter was needed... I thought that my old GeForce 8800 GTX was not just conversion right.  I realize now, is not the case and this is something with this monitor specifically.

If HP... or someone else... How can I solve this problems?  Forget the OS I installed.  Suppose that I just bought a new PC which is not preloaded and I hooked this monitor HP.  At least... I should be able to see the BIOS.

Any help is greatly appreciated and I know that others have the same issues.  I just, I saw not only the question clearly stated in any other thread... so why I start this one.  Maybe I can save people $300 on a new video card... like what just happened to me.  =)

Thank you!

Hello

Check the BIOS if you can alter the output of dp.

> I thought that my old GeForce 8800 GTX was not just conversion right.
> I realize now this is not the case and this is something with this monitor specifically

I don't think that - dp has other signals than hdmi or dvi.
PD can deliver dvi or hdmi, as the source switches to the old configurations, but most older dvi or hdmi sources don't know dp, so cannot deliver the right signals.

    We got 5 HP Elite L2201X screens vga - display port adapters and cables vga 1 meter.

    When you connect all upward, the computer will detect another monitor and you can configure the parameters of 2 monitors, expand the office and resolution etc.. No matter how we try we can never obtain an image to display on the screen.

    the front LED light is still orange. If you power on and off, the LED turns orange then white.

    We tried different computers, screens, vga, combinations of vga cable adapters, we get the same result evertime. We do not have a computer with a display port, so we cannot test the display port to display the port option.

    All windows computers 7, all computers use the VGA output with vga, display port adapter. Each computer detects the monitor but nothing shows an image.

    VGA is analog, the dp is digital - it will be difficult to find a converter for it.
    Even from DVI / dp, you need something like this:

    Your card will not work as the other sense, and only if the source can provide signals analog vga.

    You will need to buy a graphics card with dp for this race.

  • My hp pavilion elite hpe-204f video does not work

    My hp pavilion elite hpe-204f video does not work so I replaced it with another video card that worked. After installing the card and start the system I saw the video on my monitor. Great! I need to replace my video card. No problem.

    Afer by purchasing and installing a new video card, I have no video. I put a new one in another computer. This works. I put the video card which worked yesterday... that did not work.

    Then, I put the original video card that I thought that did not work on another computer and Yes... it worked.

    Should I assume that I have a bad graphical location on the motherboard? If so, short of buying the same motherboard is there anything else I can do?

    Thank you very much for the research.

    Hello

    The integrated video processor still works when the video card is removed?  If Yes, then try this memory bootable Diagnostics CD. Download memtest86 iso file and burn the disk using Imgburn.

    If the above is successful, then re - install the map graphic and clear the CMOS.

    Another thing to try:

    A good cable video know.

    A known good monitor.

  • HP Elite L2201x works only with my passive hdmi adapter? Always "standby mode".

    Hello!
    My HP Elite L2201x monitor is still in mode 'sleep' when I try to connect it to my desktop Acer Predator with a passive adapter DisplayPort to HDMI. Computer can connect to the other monitors with the HDMI cable. Not sure if the problem is the adapter or the monitor.
    Thank you for taking the time to read this and understand.

    If your computer has a HDMI output and the only entry it has HP Elite L2201x monitor is a DisplayPort, it won't work. Please see the DisplayPort.org faq page which States;

    Q: I just bought a monitor that only has a DisplayPort connection. How can I connect to my computer that has VGA, DVI or HDMI?

    A: there is not a cost-effective way to do it. The available adapters operate only from a computer of DP to VGA, DVI or HDMI monitor and not vice versa. If you have a desktop computer, you can buy a graphics card with DisplayPort. Our best advice: before you buy a DP only monitor make sure you DP on your computer.

  • Elite 7300 MT: update UEFI BIOS for Elite 7300 MT

    Hi people,

    I have a Hp Elite 7300 MT with a mobo Pegatron and FRIEND bios v 7.12. I am perfectly aware that this bios does not support the new UEFI protocol that is required to install the new CSA video.

    I intend to move to a GTX 1060, and I want to know how I can improve my bios so that it works with UEFI and I don't have to worry about finding a card that is legacy compatible BIOS.

    I do a lot of research on the web and have not found a solution. Appreciate your support.

    There is NO upgrade BIOS.  The best map yet available is the EVGA GTX 670 4 GB.

    It is snly if you buy a model that has a legacy BIOS compatibility.

    Sapphiretech cards that have inherited the BIOS compatibility and some who have actually a physical switch on the map to allow switching between UEFI and compatibility existing BIOS. See the catalogue following Sapphiretech.

Your office has not been handed over with a power supply that feeds it, then you must also upgrade the PSU. Choose a nice modular unit by a manufacturer as a Corsair.

  • Pavilion Elite m9452p: Flying Blind with a HP Pavilion Elite m9452p - no video at all - HELP!

    It is a Core 2 Quad Q8200 processor Intel PC with 8 GB of RAM and 750 GB drive HARD + 1 TB back up drive running Windows 7 Ultimate 64 bit (it came with Vista 64-bit home edition Premium, but updated for win 7 just now).

    It has always worked perfectly, but last week there was no video at all when I turned it on. The monitor says 'No Signal' on an otherwise black screen when turned on.

    HDD lights indicate activity and I can hear readers spinning and the LEDs for the DVD and the wireless signal light up as well.  In addition, ports Ethernet led Flash and show activity, as does the DVD player if I put a disc, but no video at all.

    I did the following to try to resolve this problem:

    1. I checked the monitor I was using is working;

    2. I always connected this PC to another monitor DVI to work with no luck.

    3. I have connected the PC to a working VGA monitor with no luck.

    4. I connect the VGA monitor to the VGA port, integrated with no luck.

    5.i tried to boot in the BIOS, but there again, no video is not sure if it goes to BIOS or not;

    6. I have read somewhere that the built-in VGA port will not work if a video card is present, so I removed the video card of exisitng and connected to the VGA integrated with no luck;

    7. I bought a replacement video card (it came with a MSI V240 500 MB PCIex16 card and got a card XFX Radeon HD 5450 1 GB PCI ex16); I installed the new card and tried again without success;

    8. I don't remember if this PC was set to beep on the POST before he always started quickly and without problems. Now that I'm looking for any beeps, I don't hear everything but yet once, can't remember if it still beep before;

    9. looks like it's a hardware problem, but I also tried to boot from a drive of W7 64 Bit repair, but even once, no video so don't know if it works.

    The last thing I remember having seen it was a Windows Update I think to include an optional update to the video driver. I don't remember if I acdcpeted that one or not, but it seems to me that the drivers for the MSI card (nVidia, GE Force pilots I think) that does not correspond with an AMD Radeon graphics card drivers - this is why I opted to get the Radeon card).

    I have not tested the original map, mainly because I don't have any PC with which test (I have a Core 2 Duo Pc with a PCI slot ex but not an ex16 PCI card. I don't know if this card would be retro-compatible with this PC or not).

    I vaguely recall disabling the onboard VGA in the BIOS, but do not remember if it is with this PC or another.

    I hope someone has a way to put video on so I can uninstall all recent drivers or updates that may have caused this (or I can enable VGA integrated in the BIOS).

    I sure hope the MoBo is not messed up (it does not fuel upward hard drives, the DVD player and the fans, etc.) but with no video, it is difficult to know what is happening.

    Help!

    OK - SOLVED!

    After re-reading my post, I realized that if the BIOS for the integrated video card setting had actually been changed, I could re - put these default settings by resetting the CMOS.

    I had not tried to clear the CMOS by the cavaliers to the MoBo, so I'm the manual MoBo and I cleared the CMOs (which would reset the BIOS to factory settings). I restarted the PC and voila! I now have the video!

    Sometimes the simplest things will solve the whole problem!

    I felt bad that I couldn't solve this problem, as I can usually solve everything that came out on any of my systems, but here I answer my questin oiwn and solved the problem - I hope this will help others too!

  • HP elite 8000 usff master key bios password

    Hello all, need help

    I bought recently used HP elite 8000 usff

    great small desktop computer

    Problem is the main key to the password for bios, product number is AU248AV and serial nuber is (deleted content)

    I also tried unplugging the power supply and push and hold the CMOS on the motherboard, no results.

    Help, please!

    Hi, @DimitriSerbia :

    Here are the instructions to clear the BIOS on your PC password.

    There should be a green rider of password, you need to remove to clear the P / w.

    See the general troubleshooting guide to find out how to erase the password - Annex B, BIOS 59 page.

    http://h20565.www2.HP.com/hpsc/doc/public/display? sp4ts. OID = 3459241 & docid = emr_na-c01162207 & docLocale...

    Failure to erase the BIOS P/W stringent security has been enabled in BIOS which prevents erasure of the BIOS password.

    The only solution for this would be to replace the motherboard.

    The rigorous security BIOS setting was added starting with the model of dc7900 business desktop series.

  • Pavilion Elite M9066.sc video card

    Hi all!

    I'm having trouble installing my new GPU (Asus Ati Radeon HD EAH5670). And uninstall my old driver (NVIDIA GeForce 6150SE nforce 430) cards.

    First of all; Windows (win732bit) does not recognize the new card. If the map seems to work fine when it is plugged. I installed the drivers, still nothing.

    The problem with the old driver is; Whenever I uninstall it, it disappeared, but when I restart my pc Windows says he has detected new hardware and installs the driver to return. Even when I uninstalled and then installed the drivers for the new card. He always does. And when there is no video plugged card at all it still found.

    I've tried everything I know to do, I fought with it all day and night... Now, I'm just all out resource. If anyone can help me with this I would appreciate it a lot!

    Turn off the PC and try clearing the CMOS.

    Turn on the PC and go into bios (setup) and make sure that the bios will recognize the new card in the video slot PCI-E x 16.  If the card is not recognized by the bios, then the card is probably not compatible with your motherboard and bios.  I have seen this situation with older PCs and video cards ATI 5xxx.

    There is another possibility. Your PC has a 300 Watt power supply unless you have upgraded.  The ATI 5670 requires a power supply of 400 watt, at least this model VisionTek ATI 5670 requires a 400 Watt power supply.

  • No video on bios in my new 8900 XPS after changing the default GPU 745 for GTX 550 TI

    I'm having a strange problem where no video is displayed on the screen using my NVidia GTX 550 TI.

    Only when the system completed start-up I get the windows login screen and from there everything is ok. This problem only occurs when windows is not yet loaded. by hitting the "F2" to go into the bios screen remains black and no activity is to be send to the monitor. Any ideas what is the cause?

    Hi Richdtv,

    Your post belonged to the desktop video forum.

    Please don't forget to provide more details when you post it. For example, I assume you are using UEFI. Did you disable secure boot? The new card supports UEFI?

    2: Press ENTER, then F1 to enter the bios.

    3: enter a blank password (before, with the old bios, I did not put any password, so it didn't asked me password), I don't know why without password, he asks again?

    4: try to nagivate the menu, but can only nagivate to records, all fields where have settings cannot be selected. When I tried to enter, he seemed to BEEP.

    Anyone know about this?

  • HP Pavilion Elite m9340f replacement video card and power supply

    Hello

    I bought my HP Pavilion Elite at Best Buy m9340f in 2009 and brought it to the Venezuela where I live now.

    My video card, started making the noise of the typical fan geforce 9500gs can do. The temperature of the gpu is very high (from 73 ° c without playing or watching videos!), and I'id like to replace it as soon as possible before my material fails completely.

    But the power supply 350w, to replace any video card decent needed to change my diet too. I have not the slightest idea of what type of power supply should I buy, and if I should replace the case too. My intention is to keep my cpu, my mother, my hard drive and my ram (purchase of a new system to the Venezuela is out of the question because of the barbarian prices in this country).

    Then to take the questions in order, I'll here:

    -I want another video card (geforce 9500gs is known for his failure, so I want to upgrade to a more powerful card)

    -To do this, I need another power supply, so I need recommendations on the provision of market models which CORRESPOND to my HP Pavilion Elite m9340f or

    -replace also the case: what kind of business should I need that corresponds to the motherboard of benicia

    Thanks in advance

    The information below was previously published by Big_Dave in response to several other posters about their questions about GPU upgrades. Prices shown are in U.S. dollars and for American retailers.

    Your PC has a 350 Watt PSU if below video cards will work:

    $50--->NVIDIA GT 430 9.6 Gbps - single slot width

    $65--->NVIDIA GT 520 8 Gbps - single slot width

    $80--->NVIDIA GT 440 25.6 GB/s - single slot width

    $130-->NVIDIA GT 545 43 Gbps - location single width - could be hard to find but perhaps only in the store

    $110-->NVIDIA GT 240 1 GB DDR5. 54.4 GB/s - single slot width. This card does not support DirectX 11 which is eventually used in some of the latest PC games but it's a great performer.

    Review the performance of NVIDIA specifications. Look at the specifications of strip memory bandwidth and level of DirectX support.

    I normally don't recommend video cards AMD for PC with a 350 Watt power supply as AMD provides 400 watts or more for most of its video cards.
