Dell Optiplex Goes Into Sleep Mode Instead Of Loading Bios?
Mar 14, 2012
I got a Dell Optiplex GX520. When I try to boot, after the windows logo comes on screen, the pc goes into sleep mode. This also happens in safe mode. I found out that it had a faulty HDD. So I replaced it. However when I try to start from Windows install disk it goes into sleep mode right after it shows de Loading Windows logo. I tried to go in to the bios to load the optimized settings but when I press F2 to load the system setup the computer goes into sleep mode.
So basically I cant do anything to boot or to re-install Windows.
some other things I tried:
- check PSU with PSU tester: PSU ok
- boot without DVD station: still going into sleep mode
- boot in safe mode: sleep mode again
- last known good configuration: sleep mode
- swapped RAM: still same issue... sleep mode FTL
I cant test GFX cause its on board and theres no AGP or PCI-e slot on the mobo.

So my computer went into sleep mode.... its really hit or miss with this computer so when I finally get it back up and running, I will completely disable sleep mode.Sometimes i can click the mouse and it wakes up with no problem, but sometimes it would reboot on its own and just keep trying to boot and restart.... continuous boot loop.... so when i want to remedy this, I just clear the cmos by unplugging the power supply and disconnecting the cmos battery.... it always worked I tried to pull the battery and left it out for 60 minutes.. popped it back in and it won't let me get into bios. None of my keyboards will light up for me to hit delete to get into bios.... not even my PS2 keyboard.... it will just continue to turn on, and show the logo screen telling me to hit various keys for various functions and then it will reboot on its own and it will just continue to do this and will not let me hit a key to get into the BIOS screens
my computer was getting too hot i went into the BIOS and changed a few things like turning off the auto-controlled fan sensors, FSB i put down to 200 and the CPU voltage I changed to 1.0Volts. I started up windows again. This time though, the option for "hibernate" had disappeared. So i looked up how to put it back on. and changed the power settings to "never" allow "hybrid sleep". So now i have the option to hibernate again. But the strange part was this. When I put my computer to sleep now. It apparently shuts down fully. (no more blinking light) then i turn it on and it re awakes from sleep. It's actually nice to have it this way. I tested it to see if i could disconnect the power fully and then still restore it back from sleep. Sure enough it lets me disconnect the power for up to 5 seconds then i plug it back in and it will still restore back from sleep. I guess my question is. Is the computer using even less power now to keep the information on the RAM. I read somewhere that on average your computer uses about 6 watts while in sleep mode.
I'm having a problem with my notebook. It keeps turning display off after idle for 2 or 3 minutes and going into sleep mode around five minutes after that. I did change and set power system in control panel many times but it did not work. I'm running on Window 7 home basic 64 bit.
Ok so I just finished my first gaming build and it all came together nicely, however I can't figure out how to download windows 7 pro 64-bit form BIOS?
And the windows disk is a copy so that might be the reason why I can't boot into windows idk for sure though any advice would be awesome!!
i have msi cx640 model laptop and it is showing error like BOOTMGR is missing pressctrl+alt+del to restart, and when i insert win7 bootable disk it is not booting and when i try to load bios to view boot disk priority by pressing f10 suddenly msg appears that is bootmngr missing it is not allowing anything to operate
I haven't touched this laptop in a while. I received a virus which then slowed down my computer and made it really really slow to get into the windows log in screen. It wouldn't go past that. Now, 2 months later, I'm trying to install Ubuntu as my only OS. I hope this will get rid of whatever past problem I had. Is this true? The problem with this, is when I power it up and turn it on, the computer only goes to the "Toshiba Leading innovation" H2 BIOS screen. From here, the laptop screen keeps turning black/blank at random intervals (the disk drive kicks up after it turns blank). The screen returns to the BIOS screen... and I keep hitting F12 and nothing.
So my laptop (acer aspire 5745g) has stopped working.I was using it normally until i received the blue screen of death and it shut down.From then on, i tried to turn on the laptop and it would show me the windows loading page then it simply turns black with a flashing _ in the top left.Rarely when i turn it on it loads up normally but it seems to have even stopped doing that.I did some of my own research and many people suggest hd failure or ram?If it is as simple as above i can buy the hd or ram and install an os myself.
p.s. I can see the hd in the bios and i used an external hard drive enclosure for my 2.5"" sata on another computer to which my surprise i was able to extract the C drive files.
I got a new 22" Acer Monitor yesterday and I had a 1440 x 900 - 19" Acer before.For some reason the splashscreen of the motherboard and bios are not loading in full screen but the OS works fine even the login page. It is sort of centered with a black background How can I set it in full screen please ? It is really bothering me. My Graphic card is Gainward Gtx 275. The motherboard is Asus P6T SE.
Ps. There is no option on the monitor that says fullscreen or widescreen.
It's a dell insprinon 1510...my wife's and was doing a download...BIO's when it shut itself off and now won't even come back on when I press the power button. I called Dell and they say...since my warranty expired 4 days earlier it was of couse, not covered and am wondering if it's the motherboard or something else?
I'm trying to fix a vaio laptop at the moment and am a bit stuck. The screen doesn't go past the vaio. It just before the windows logo would normally appear. I tried using the windows 7 cd to try a repair or cmd/chkdsk etc, but the OS wasn't found/listed. I also tried to do a clean install and the HD wasn't detected by windows 7 setup. I also tried booting up with ubuntu and the HD still wasn't detected. Can I assume this is a busted HD? Should I still shoot for a bootage diagnostic cd for the hard drive?
I bought 2 generic fans for the optiplex 755. They have different plug in. I was told I could use the power supply. I don't see and place tp plug them in.
wreaks havoc with my Norton full system scan. It is scheduled weekly, but never does it, because my computer is on, but sleeping. How can I get the scan to not stop during sleep mode or scan if it's in sleep mode? I having to constantly unsleep my computer or change my control panel settings then change it back.
Has anyone installed Windows 7 on a Dell Optiplex GX 280? I am trying to install and and I get as far as the initial "starting windows" where setup begins at, and I get
I have a Dell Inspiron laptop that is running windows 7 home premium. I'm trying to set up an external monitor to mirror my laptop monitor, but all i can get it to do is set up the external monitor as a dual monitor. I want to connect the flat screen monitor to my laptop and have it display the same screen that I'm seeing on the laptop. Anyone know how to set this up in Windows 7?
in the past i had a seperate personal hd for my work laptop I would take my work HD out then install my personal drive in and it worked great. But now on new laptop there is a biosandhard drive can I still switch hard drives or will it not work or will my work know I swap. Them.
I haven't installed any new drivers/apps. I literally just clean installed the RC (build 7100) over a copy of XP Pro (the usual windows dual boot menu at start) and XP is still fine but when I log into win 7 it's slow as can be. incredibly slow is how I would describe it. Anyway the weird thing is the CPU usage and memory usage are low so I can't figure it out.
maybe it's disk usage but I can't even run any portable diagnostic software because it's so damn slow. Is there anything I can check. it must be something simple. And I'm sure somebody else has tried it on a GX520 business machine.
My background is that I have a Dell Optiplex E8400, 4GB Crucial Ram, 2- SATA CDRW/DVD's, 1.5GB SATA Seagate HD, ATI HD 3650 video card that runs dual 19" monitors.
I primary use my computer for Adobe Photoshop and photography items with the occassional MCE movie.
My question is that on Dells support site they have the 64 bit Vista drivers but no support for Windows 7. I would like to run more RAM to speed up my Photoshop usage and wondering if there would be a dramatic difference between 32bit and 64bit for my usage.
I have a Dell Optiplex 745 (160 GB HD and 8 GB RAM) which originally came with Vista 32 bit preinstalled. I received Windows 7 Professional as a gift. i performed a full install on the machine. 7 runs fine on the machine except that the system freezes up after a few hours of operation. I updated all the drivers via reviversoft.com but the issues is still recurring.
I am using dell optiplex gx280. I have installed windows 7 32 bit but I'm having problems getting the video driver. I've searched the net but to no avail.
