I have an APC Switched Rack PDU powering a number of servers in a remote datacentre. After a recent power outage, I noticed that the outlets did not automatically default to the On status once power was restored. Having reviewed the Web UI, I cannot find this option.
I'm not certain of the model number (it doesn't appear to be visible in the Web…
I am developing an application on a Linux embedded board (runs Debian) e.g. Raspberry Pi, Beagle Board/Bone, or olimex. The boards works on an environment that the electricity is cut unexpectedly (it is far complicated to place PSU, etc.) and it would happen every day couple times. I wonder if the unexpected power cuts would cause crash/problem…
I have a Microsoft brand USB device that acts as a receiver for a wireless Microsoft Keyboard and a wireless Mouse. When it's operating normally, there are LEDs on the device indicating Caps Lock, Num Lock and Function Lock, of which the latter 2 are usually lit. It is plugged into a Dell Isnpiron 531 with Windows 7 32-bit running on an AMD…
I need to power 16 IP phones over their Ethernet connections. I am in the process of changing our switches and only the phones need PoE, everything else is powered by mains cables.
I have contacted the supplier of the phones and for 16 mains leads it will be close to £300. I know it's possible to get a PoE injector that goes between the…
I had just turned my computer on and windows was loading when the power in my neighborhood went out.
Normally, when I turn my computer on, the video card fan spins up, then slows down, POST and windows boots.
Now, after the blackout, the video card fan spins fast and wont stop. Nothing is displayed on the monitor. The monitor does not…
I wan't sure where exactly to post this question, but this one seemed the most relevant.
I have a Dell LCD monitor running off a Dell Inspiron 531 tower with an Nvidia GeForce 8600 GT video card.
Just recently, when I turn my computer on, the display immediately enters its "Power Saver" mode, and never wakes up. This problem doesn't…
My Compaq Presario CQ40 (yeah, its pretty old) suddenly turns off after about 1/2 - 1 hour usage without any notice or warning. The power cable and adapter works fine (indicator bulbs show that power is given to the laptop), but it seems like machine suddenly plugged off from the power source. And when I try to switch it on, after…
I recently bought a printer, Samsung ML1865W, a wireless laser printer. It works very well, wirelessly until after a while, it goes to power save mode when the printer goes offline. I then cannot connect to the printer (pinging the ip and various ports associated with it do not give any response) until I power cycle the printer. I…
How to stop blanking screen although I am active on Ubuntu Karmic on old IBM Laptop 600E?
After some time of working on the machine the screen goes blank. When I hit ESC on the built-in keyboard (not on the attached USB keyboard where I work) it comes back and everything works fine until the next screen-blanking.
I suspect it is…
I have a problem similar to the questions posted here and here. This is my config:
Asus M3N78-EM, with AMD Phenom X3 720 2800 Black Edition, 4GB Transcend DDR2 RAM, Nvidia 9400GT. HD is a 160 GB IDE, and a LG IDE DVD-ROM. The power button is a bit off, I have removed the cover of the switch, and the only way it turns on is just…
Hi,
I'm Christmas-present-buying, and I'd appreciate recommendations for a USB HD with an optional mains power input. I've hunted, but can't find all the information I want (partially due to sketchy product specifications).
Background:
This is for a digital TV which I do not own, and so I'd like to get it correct first time.…
First of all, I live in Italy, Europe, so keep this in mind for Volt/Watt considerations. Standard voltage in Italian apartments is 220V.
In my living room I have 2 APC ups, one being an ES-550 and the other an ES-700
They each have 4 slots for surge protection only, and 4 slots for surge protection + battery backup.
Just…
Problem:
The SSDs in our servers require a power cycle (i.e. off/on, not reset/warm reboot) after a firmware update.
Thoughts:
Using 'ipmitool chassis power cycle' I can cycle the server's power. However this would cut the power while the system is still running, filesystems are mounted, etc.
What I basically want is a…
Hey everyone this is my first time here, so, my computer got pulled out of his place the other day by accident and it never got back to working decently ever again. I just stopped using it because everytime i power it on, it restarts. Some times it doesn't even reach the desktop, others it even allows me to run a game or…
Our organization was robbed and definitely it was inside job. I was set up. I work as a manager and as system administrator in this organization and everything goes against me. The only clue I have is that someone accidentally or intentionally turned of a server that is in the office indicating that some one was…
Normally I can slip my running laptop into a backpack, go somewhere, and if it's no more than about half an hour later, it'll still be running. At the destination I plug in the AC power unit and all is well. I run it off of the AC unit before and after the trip, have the screen at less than full backlight…
I have a hackintosh running on a Gigabyte P55M UD2. It has run without a single issue as a hackintosh for about 9 months, and the machine is about 2.75 years old. Never had issues when it was just linux box. Power supply is 750 Watts.
It recently started spontaneously rebooting, no seeming connected to any…
Because of convenience, I had to move my laptop to another room away from room where I always ran laptop on UPS without using battery. Since so far I always run laptop on battery, I question the proper usage to prolong battery life.
Currently I run laptop on battery with power supply so battery is…
I have ASRock Z68 Extreme3 Gen3 motherboard recently updated to 2.20 BIOS version. OS is Windows 7 x64. The problem is after that update full hibernation (by that i mean full system power off) stopped working although everything was fine before. Now when I press hibernate, sleep in initiated as…
Periodically, while using my Windows 7 Pro desktop installation, the screen suddenly dims. The brightness is about 75% normal (estimate). It's as if I am in a power-saving mode on a laptop running on batteries. But this is a full desktop installation.
I know it is not a hardware glitch or…
Currently when I close the lid of my Acer laptop running Windows Vista, the laptop does not power down; however, when I open the lid it does. When looking at the power settings it is set to power down when closing the lid. The trigger to this seems to be the lid being opened not being…
Currently I've only a 300 watt PSU and my pc is working like a charm but with all the components it should use the psu to the max. Recently I've read about 80 plus certificate and I'm wondering if it's worth to buy a 80 plus certificate psu? My power cost last year was also higher…
Hi,
This is on a Lenovo X60 running Windows 7 Professional.
This is just a pet peeve of mine, but I was wondering if it were somehow possible to have my laptop autodetect whether any media/music is playing on and change/switch the "Close lid" options under Power Options, ie.…
I've ordered a new hard drive to replace a bad one in a Dell Power Edge R515.
The manual covers obvious topics regarding physical replacing of hard drives, but I've never done this before on a production server where RAID is involved.
I've heard people talk about this topic,…
