Compaq Presario CQ5500F: Compaq Presario CQ5500F has no support for cmos battery

I'm refurbing this machine and it does not have a CMOS battery on the motherboard support.  See where it should be, but looks like it was never installed.  There is a new technology that does not require a battery?

Hello

The CMOS battery (or RTC battery) is used to allow a computer to maintain the non-volatile memory Basic Input Output System (BIOS, IE).

Whitout CMOS battery, the computer will boot but you may need to change every time you start depending on how configure you your machine. The function of RTC battery is not important now because a lot of people now use the timer/clock NTP or internet.

Kind regards.

    What battery I need to buy to replace battery CMOS (lose the BIOS date/time).

    All traps to replace?

    @LechKL, welcome to the forum.

    Here are the computer hardware reference Guide .  On Page 46, you will find a guide to replacing the battery.  Read this section very carefully.  In most of the computers battery is a CR2032.  The instructions state that you must use a spare battery supplied by HP.  However, you can us HP Partsurfer to see if they recommend a battery.

    The process should be simple.  There are detailed photos to help you.

  • MS has stopped support for Windows 7 updates?

    I tried to get Windows 7 to download and apply updates after reloading my laptop from scratch. If I load MS System Center before SP1, System Center hog all the resources and the laptop has no effect.

    If I load SP1 right after I installed Windows 7, SP1 takes 8 hours, with TrustedInstaller taking all of the resources and the SPINST barely get all resources, even if the updates are disabled. A control is completed, for updates took two days until now and still nothing. I have an instance of SVCHOST that takes between 1.5 GB 2.5 GB, as it intentionally uses the resources to prevent updates of race.

    Last year, I successfully rebooted Win7 on more than 50 laptops, I support computers at a local college, so this is not something new for me. I also have been loading OS on the midrange and personal computers, including Windows, Linux and Mac, for 20 years.

    If this is the way for Microsoft to force updates to Win10 by closing the updates for Win7, I will seek to Linux or Mac.

    Laptop is a Dell Inspiron 1520 with a Dual Core 2 GHz processor, 4 GB of RAM and a 500 GB HARD drive. Been running Win7 on it very well for a few years, reloaded just because the HARD drive failed.

    I also tried various patches KB as suggested by other posts of loading, but it does the same thing, just using all resources while doing nothing.

    The value of the automatic updates to "never check updates" and then restart Windows. Then, install KB3020369 and KB3172605.

  • Qosmio X 770 has no support for 1600 MHz and 1866 MHz RAM

    Hi all

    I posted another thread on the 16gig working in the 770 x kits. I tried the new Kingston 8gig kit now. The Hyperx 1866 MHz C11 2x4g kit. It does not give a drop of performance increase, primarily because he is only recognized as 1333 MHz in the Bios. The Bios will not tell you the rate at which memory is running, but I ran Memtest and it is coming as 1333.

    Dear Toshiba...

    All I want for Chinese NY is a BIOS that looks more like every other freakin BIOS. Something with more information and perhaps a few more adjustable features. I know you will get right on it, so look forward to 1.5 limitation and the RAM speed setting.

    Cheers in advance,

    Tim

    Hello Tim

    Sorry, but don't you know how it works?
    I mean if the speed of the FSB 1333 MHz is, do you think really that a BIOS update can make it faster?

  • Microsoft has stopped support for Windows 7 Media Center's Electronic Programming Guide?

    I've been using the Windows 7 Media Center to watch and record local televisions more of one year.  Now, my guide-schedule is not download new data.  I tried several times to update manually the programming data.  The EPG shows the update succeeded, but no new data is displayed.  Microsoft stopped providing data to guide programming?  If Microsoft still provides programming data, what can I do to fix the problem?  PS: I have similar problems on a second computer.

    After re - run the TV Setup at least 100 times, it * finally * downloaded and updated to the source of Rovi.

    Keep trying, it will work eventually.  Try to run the TV setup during off-peak hours, such as early in the morning.

  • LR4 has captive support for Nikon D5300?

    I use LR4 and have discovered that it does not support the for the D3200 Nikon tethered shooting.  I need to upgrade to get this feature and have heard that the D5300 is supported, but I was wondering if anyone can confirm this.  Thank you in advance for your help!  :-)

    Attached to the camera in Lightroom support

    As you can see, the D5300 is supported starting with Lightroom 5.5. There will be no updates that will make it possible to tie you into Lightroom 4. So you will need both a new camera and a updated version of Lightroom for attaching the support.

  • Compaq Presario 5400US - need network drivers for XP Home Edition. Wired connection.

    It woun't connect to internet using a good modem and cable (other PC connect successfully using this same equipment). When I type IPCONFIG, I get 2 results, one for Local Area Connection2 for LAC3. Two of them have 169.254.xxx.xxx IP addresses. Both Suffixes DNS blank and empty default gateways.

    When I go into network connections, the LAC2 says "Limited or no connectivity", but it lists a Linksys LNE 100TX Fast Ethernet Adapter. Linksys? I don't have any Linksys product. LAC3 says 'Connected' with the help of a WAN network driver. However, in the Notification area network connections has the same yellow triangle as LAC2. When I right click the icon in the Notification area and select "Repair" I always get the following ".." following action cannot be completed: renewing your IP address.

    If I right click LAC3 (the one that says 'Connected'), click Properties, click TCP. IP and select Properties, it is set to get an IP address and an address of DNS server automatically. It is also the same for LAC2.

    Client DHCP, DNS Client and call the CPP are started.

    I tried ipconfig/release, ipconfig/registerdns, ipconfig/flushdns, netsh winsock reset. When I run it ipconfig / renew I get messages (after he is sitting there for 2 minutes)
    An error occurred during renewal of the Local 2 network connection interface: unable to contact your DHCP server. Request timed out...
    An error occurred during renewal of the Local 2 network connection interface: unable to contact your DHCP server. Request timed out...

    A run chkdsk /r have run the command netsh int ip reset reset.log.

    So, I went 2 network cards, restarted in the device and removed Manager and let Windows reinstall. Windows creates a new connection to the Local network (LAC4, 2 and 3 are gone). It only reads limited connectivity or none and is using Linksys LNE 100TX Fast Ethernet Adapter, like the previous LAC2. The previous LAC3, who uses the network never got WAN driver reinstalled. I don't understand.

    Since an adapter Linksys on a wired connection seemed odd I have tried to find what should be the correct network driver.

    I google "Compaq Presario 5400US" "driver ethernet" OR "network driver" and was taken to a page of drivers HP, which I think makes sense since HP now owns Compaq
    http://h10025.www1.HP.com/ewfrf/wc/s...UCT=93284#n430
    This page has nothing listed for network or chipset cards.  This, of course, has no meaning for me.

    Can anyone help?

    Select this version from the drop-down list on the link that I posted above.

    Depending on the size of file, it does not resemble an auto install file. Accept the agreement and unzip the file into a folder.

    So, download it to a folder and go to Device Manager.

    Click the network card in need of drivers, and then select manual search for drivers. Navigate to the folder where you extracted the drivers and the driver should install.

    Hello:

    Unfortunately, your model will not support 2 x 4 GB of memory.

    This is because it is equipped with an Intel Celeron processor, your laptop is the chipset Mobile Intel GL-40.

    This chipset only supports a maximum of 2 x 2 GB memory.

    http://Ark.Intel.com/products/35501/Intel-82GL40-graphics-and-memory-controller-hub

    By the way... 2 x 4 GB memory DDR2 would cost a lot of money.  It was the cheapest I could find.

  • Compaq Presario S4500UK won't start after disconnecting from the wall outlet. What is a CMOS battery problem?

    Reconstruction of recent software with HARD drive internal extra (March 2011) under Windows XP/Linux dual-boot installation worked fine.  CD/DVD RW drive, started giving errors so replaced cyclic redundancy check drive a week ago.  All still OK.  Change of electricity supplied and increases energy use conciousness off the machine to the outlet of the overnight after normal shut down.  Machine will not re-start not in the morning.  Not load BIOS; all lights came briefly and then die after 3-4 seconds with power still led on.  You can get a similar effect by plugging the keyboard into the PS2 Mouse Jack I did once!

    After 20 minutes or so try all kinds of things managed to boot from the CD of Linux.  Shut down/restarted and everything is fine so I don't switch off at the wall.  Also seems to be OK after brief power off for 5-10 seconds but the problem persists with any long disconnection.  It seems that after 10 to 15 minutes from power-on and 2-3 attempts to restart, BIOS comes up and all is well, but he stopped in the middle of a start of Windows or Linux on a couple of occasions.

    Am I right in thinking the problem might be the result of a dead CMOS battery?  The reason that I ask is that the clock seems to keep time OK and there is no apparent problem with the BIOS once it loads.

    Any help/advice would be much appreciated.  New config info below.

    I don't have all the answers so I went forward with replacing the CMOS battery, but that did not help.  The problem is also obvious if I turn it off and leave it for an hour or more before trying to restart even if I do not unplug the wall plug.  It seems to take about 15-20 will start again before it fires.  I would be really grateful for any clues as to what is wrong.

    OK, guys.  I finally solved the problem.

    After you have calculated the power needed for the config curent, I discovered that, using various ways to estimate, he walked between 321W - 383W.  It was pretty weird that the only thing I added was a HARD drive and a memory stick and the wisdom of the other guys on this forum, it's that there is a lot of capacity within the factory installed power of 250W.  Yes and here's the rub: the modern replacement devices usually have upgraded capabilities and use more power.  And so when I replaced the drive CD/DVD RW added a few watts, as the sectoral approach of the floppy drive.  It appears also that the optical USB mouse needs more juice than the good old PS2.

    I just installed a new 450W PSU Powercool and Bingo!  The processor is faster, too.

    Hope that my pain and trauma saves someone else having to suffer the same.

    Hello:

    Here is the link to the service manual for your laptop. Chapter 1 lists the supported processors.

    Processor Intel Core i3 2310M is not supported, but the 2330 m.

    The Celeron processor you have runs on the chipset Mobile Intel 6 series as either i3.

    By the book, I must tell you that it won't work.

    So, you can try to install at your own risk. It may work correctly, or it may not work at all.

    It all depends on if the BIOS has the microcode for the i3-2310 and other firmware supported processor.
