Adaptec AHA-2940UW card prevents POST and boot 400SC, Precision 390 and Power Edge

I have two systems: Precision 390 and Power Edge 400SC

When an Adaptec 2940UW adapter is installed in a machine, they will not start.  Power lights, but there is no video output, the system just hangs.  In the case of the 390, the fan slowly ramps up to its maximum speed.

I know the SCSI drive and the cable is good and well done.  I tried different machines slot, disabled the startup of the IDE/SATA drives, disable the option "fast boot".  The results are always the same - both computers refuse to do the BIOS POST when the adapter is installed.

My first is that the adapter is bad, but the eBay seller insists he test it and it worked.

Anyone have an experience to install a SCSI card in a Dell computer with integrated IDE/SATA controller?

The 2940UW is a 5v PCI 2.0 card.

You can use only the 2 cards of keyway UNIVERSAL PCI 2.2 or 2.3 which are 3.3V to the Pentium 4 and systems.  Mounting in the slot is NOT compatibility.  All slots MODERN 64-BIT PCI - X are also 3.3V only.

If you need this card, you will need to use a 2940U2W which has 2 SLOTS, which means that its 3.3V OR 5V UNIVERSAL

UEFI WINDOWS 8 systems will prevent this loading card or be seen in secure boot mode.  64-BIT VERSIONS of windows must also be certified by Microsoft WHQL drivers or that they will not load.

  • Satellite S955 starts not to POST and black screen

    Hello

    I have a problem with my s955 (14 months). He is not able to start more. When turned on, I hear only the cooling fan spins up and down and nothing more. The last time, it took almost half an hour to work around this failure. When turned on it shows no problem at all. When you stop it is better to pray. It now seems to be missing. After an hour, I see no sign of life except cooling fan activity.

    I went through all the stuff mentioned in another forum of Toshiba as turned off, remove the battery, keep and maintain the power button for at least 60 seconds. I even replaced the RTC internal Li - ion, but without success. Because it is not covered by warranty more I opened it. No sign of didn't burn except a suspicious oxidation of some contacts.

    I contacted Toshiba Italy (even if it is a U.S. model.) and I expect a possible answer next week. I ran out of the possible solution except replacement of mobo. Is there anyone around who has the same problem? Could you please give me a help?
    Thank you and best regards

    Pyder

    Hi, not Toshiba Italy news but I found a Toshiba authorized service workshop that may solve this problem. It seems that, beyond other speculations, the problem may be issued by the fuse of power mainboard (read this answer interesting of maxtek73 [http://forums.toshiba.com/t5/Batteries-and-Power/My-Toshiba-Satellite-Laptop-Will-Not-Turn-On/m-p/584008#M11147] at the end of the post). It seems reasonable. In fact, keyboard, dvd player, charge battery, hd, and cooling fan are powered by the motherboard. It seems that there is not enough current to pass initial tests before POST. This could explain why the cooling fan trying to run at maximum speed, but he can't. I had to remind that to turn on, no equipment TI push fans at max speed and then slow down to normal speed before entering the POST process. I'll have a conversation with the technician of the workshop and I'll keep you in the loop.
    Best regards

  • Portege R500: Card reader SD and ODD do not work - drivers needed

    I have laptop portege R500, product number: PPR50E-04X04WCE.

    last year, I changed the operating system and installed windows 7.
    Since then, I can't use the dvd drive or the sd card reader.
    And the control panel it apears two unknown devices, but I can´t find the controllers for these.

    What can I do to fix this?

    I assume you found unknown devices in Device Manager.
    Check it please http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=78
    Here you can find instructions how to identify the unknown devices.

    I checked the Toshiba download under http://www.toshiba.eu/innovation/download_drivers_bios.jsp page and your Portege is listed there, but under the option ARCHIVE. It is supported for Win7 so there is no problem to install all the drivers available.

    Check it out please and let us know if you still have the same problem.

    I have firefox installed on both computers. The office displays not the split screen, but the laptop don't. I checked the posts and I have not the separator module of fox but still get the split screen when I click on a second site.

    Firefox has no built-in opportunity to split the screen. There are several add-ons that can split the screen to solve this to know what originally, using the procedure in this link - https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes

    Another possibility is that you have a few set bookmarks to open in the sidebar. If this only happens for a few bookmarks, right-click on the bookmark, and then select Properties. Make sure that the "Load this bookmark in the sidebar" option is not selected.

  • Satellite A200 - 1 M 4: Flash Cards are dark and not transparent after update v1.1.7

    Hello

    You know Flash Cards is transparent and moving flashy when pressing the FN key.
    After that I downloaded & installed PVAT 1.1.7.see card Flash became a dark, not transparent and does not move when you press FN plus (watch suddenly when pressing FN).

    What's wrong?

    PS. I have A200 - 1 M 4

    Thank you

    Nothing is fake. It is simply a new version. Toshiba has offered this setting day and fixed a big problem. Using the latest version of Flash cards were very slow and it was very awkward. Toshiba has designed the new tool and transparency is no longer available.

    I hope that you know very well that these settings are in need of more resources and laptop runs slower. But in the end I wonder: is it so important to you?

    a big thank you in advance, cheers, Aleks

    Hello!

    You can determine the type of wireless network card if you check the vendor and device ID in Device Manager. Enter the two codes on this Web site and you see what WLAN car you have: http://www.pcidatabase.com/

    Regarding your question on the partitions on the HARD disk, you should look in disk management. Maybe you need to format the first partition or create an extended partition.

    4. What is the recommended CPU to run at the same power original power supplied with my computer when I first bought it?

    5 How can. one last thing, I upgrade and replace the graphics card if this computer comes with the integrated graphics card of base/stock/default on this computer?

    I'm not very tech savy, or a computer programmer/Assistant. Help, please. Thank you!

    Image AMD A6-3650 (Liano) 100W

    No need to replace the power supply to allow an upgrade of the CPU.

    (3) graph and power upgrade;

    This computer using integrated graphics supported by the motherboard and APU. Installation of a discrete graphics card will automatically disable the integrated graphics card. This model supports a v2.0, v2.1 or card discrete graphics PCIe x 16 v3.0 Specification v2.0. For all but the most basic graphics cards, you will need to supply. I suggest using the power supply Corsair CX500, CX600, CX500M, and CX600M.
