    What is the model of the PC?
    Do you see any activity on the hard drive led? (typically has a cylinder icon)
    Does the machine sound like it is booting up?
    Do you have any lights on the keyboard? If so, when the capslock is pressed do the lights respond on the keyboard?

Automatic shutdown

My best guess is its over heating. If thats the case you need to open up the cpu and clean it up, renew the silicon gel in the motherboard chip and add an extra fan (Optional)..and voila :) But if it keeps re-booting instead of shutting down, then its a system corrupt. Then you need to repair the OS using the software CD. I reccomend you to do something IMMEDIATELY or take it to a repair statioan asap since its a server. Good luck!

Server Randomly Reboots

First, go to Dell's website and update all the firmware and install the latest version of Dell Server Administrator. DSA has logs information not logged by Windows. Next, take it outside and blast the fans with compressed air, make sure all components and cables are properly seated in their slots/sockets, turn it on with the cover off and make sure all the fans are spinning. Many servers will increase the fan speed if they detect the cover is off so this is another possible cause to the problem.
Finally, Dell servers have lifetime support, this number should work: (800) 945-3355
Good luck!
BTW: A temporary workaround might be to use a network controlled outlet that you can remotely turn off and on. Your UPS might be able to turn outlets on and off or you could get a stand alone network controlled outlet. Some can actually ping the device and turn power off and on again if it stops replying to pings. (E.g. IP Power EV-9255 IP

Fan speeds don't drop and are constantly on full power.

Hello here is the homepage:

I had this problem on another pc, it helped by cleaning the whole pc out for dust, with compressed air.
And renewing the thermal paste, between the cpu and the cooling element.

Actual control of speed is base entirely on measured temperature at some appropriate point, and a setpoint. Whether 3-pin or 4-pin, the basic control strategy is the same. For the CPU, the temp sensor is built into the CPU chip. For the case or SYS_FAN or CHA_FAN, the temp sensor is built into the mobo at some point. In each fan control loop, the measured temp from its sensor is compared to a setpoint and used to slow down or speed up that fan.
HOW the speed of the fan is changed is what differs. On a 3-pin system, the mobo reduces the +12 VDC line voltage to slow the fan down. On a 4-pin system, that +12 VDC line is kept at that voltage always, but the special PWM signal is used inside the motor casing to control how much of the time that voltage is actually turned on to the motor. The chip using this signal is a simple on /off switch, turning on the feed of 12 VDC to the motor and turning it off again, very rapidly at the frequency of the PWM signal. That signal looks like a "square wave", except that is "% ON" is varied (not constantly 50%) to control fan speed.

Try also to upgrade the bios, and look for the settings for the fan.
Make sure the fans are connected right, to the mainboard.

Good luck

Hp proliant ml350 gen5 keeps shutting down unexpectedly.

Open the top . Turn on. Populate any empty fan slots, and replace any with amber / red indicator lights. You can also try reseating. Fans are hot swappable.

You should have been using Insight Manager. Login locally and go to http://host:2301 you need the SIM administrator password. It will tell exactly what is wrong.

Ibm xseries 226 is not initializing.. the fans start when i power onn the system but not more than 5-10 seconds.. and there is no display.. there is only one processor on board right now. pls help

If you are comfortable getting inside the PC here's some things you can try.
  1. Take the side panel off and pull the memory sticks out. Now turn the PC on without the sticks in it and listen for a screaming banshie. If you hear the screaming banshie it means *********** board should be okay. If you hear no noise at all there you may have a bad mother board. 6df7c5d.jpg
  2. While inside the PC unplug all cables for about 10 seconds and plug them back in. Do this one at a time so you don't loose track of where they go. Also carefully pull the processor out and plug them back in. Turn PC back on and test. 3513f7b.jpg
  3. Unplug the power supply from the mother board and plug it onto power socket by itself without having anything connected to it and see if it runs okay on it's own. If not it's probably bad.
  4. Last but not least If you know how to boot the PC into the BIOS configuration do so and check what temperature the PC is set to shut down at.

Hope this was helpful.
Good Luck

Dell PE1800 psu wont swith off...Computer powers down but psu fan continues to run. Have to pull the power plug to shut it down.

Sounds like the PSU is overheating. Some PSU's are designed to keep the fan running to cool it down even after system shut down. I would let the fan run after shutdown to see how long it takes to shut itself off. If there are no environmental issues tat are causing overheating you might want to consider replacing the PSU.

HP Proliant ML350 G5 wont boot ,just spining.

The G5 Series is fairly new, if you're within warranty, call 1800-okCompaq.

Could be a bad cable, a bad monitor, or bad computer hardware. Any display at all or any beep codes?

On the back, the ml350 G5 will likely have an additional Network interface jack-- this may be labeled ILO. The ILO network connect allows you to use another PC on the same network to access this system (like a remote control via VNC or RDP) even if it won't power up--literally. Inside the ILO page, (you'll need the IP address of the ILO, the default account is administrator, and the default password is listed ona paper tag attached in the rear or on a sticker. If you can get into ILO via web browser: https://ipddress of ilo, you can check the Integrated log, which can shed some light on any failures.

How i turn off a fan from motherboard

The fans that are plugged into the motherboard are usually powered by the motherboard. To turn them off, simply unplug them as there is always a power flow going through the motherboard and even more to power the fans when the system is running. I would recommend keeping the fan in if possible to help with cooling your PowerEdge 1400 server, but if it must be removed, simply power your server down, and unplug the fan. Make sure your server is powered off before doing this, as you don't want to short anything out or cause a spark.
