Why does my laptop ask me to manually set the time and date every time I open it?
Usually that is an indication that your CMOS battery is dead. When the computer is turned off, the CMOS battery keeps the internal clock running, when it goes bad, the clock always resets itself.It is a small, quarter sized, watch style battery that is used to keep the internal clock running. They are good for a few years but eventually wear out like any other battery.Search for your exact model of laptop and you should be able to find images as to where the batter is located on your laptop and if it is easy to get to, you could probably replace it yourself. If you are not real sure, I would say take it to a computer shop and have them replace it for you.If it is located similar to the one in the picture, you could replace it yourself, just make sure you get the exact same battery, i.e. a 3.5 volt or 4 volt or 2.8 volt (Numbers are made up for examples) or you can cause problems with the machine if you put in a 5 volt battery on a machine that needs a 3 volt battery.
Why would anyone want to manually control their fan speed on their computer?
Because people are unable to control them automatically.This may be for several reasons:People don’t know how to do itPeople don’t have the hardware capable of regulating fan speed automatically (PWM headers).The software for automatically controlling fan speed is not well-designed for their use-case. Usually the software allows to tie things like the CPU fan to the CPU temp, the GPU fan to the GPU temp and the case fans either to the motherboard temp, some aggregate score or the CPU temp. Depending on your setup this might not allow you to engineer a working fan curve.People don’t want to have to quit their full-screen application to open up some utility to switch profiles from “silent” to “maximum cooling” or whatever. Some computers will even require you to reboot to set a different fan curve.Cases like the ones from the Nanoxia Deep Silence series have the fan speed tied to some other changes (in this case opening an “air chimney” to allow air flow). An automatic fan control would not be able to open the “air chimney” without heavy modding.For my personal rig fans are either spinning at a fixed rate or PWM controlled with a fine-tuned fan-curve.
What do Phase & Clock on an LCD monitor do?
I have 2 options on my Gateway widescreen monitor (the $600 one with component inputs and such) for Phase & Clock. When playing 360 on it thru VGA and I hit the auto button (auto-detects picture settings for you) it usually puts Clock at 9, and Phase at 30 or so. I usually jack up phase to 100 b/c the manual says it sharpens the picture, and clock i bump up to 12-14, because it stretches the picture and makes the screen look a little more natural (9 looks too horizontally squished, altho it fills the screen). Can any pro's out there tell me what these to options really do? Also, any other advice for this monitor?
Can I get my iPhone's alarm clock to play music?
There are several free or inexpensive apps that allow you to choose the song you'd like to wake up to each morning, and with a tiny bit of effort you can manually alter the iPhone's clock settings and customize the sounds. I primarily use the free iHome app which allows me to select any song from my iPod and listen to it in its entirety as my alarm song, and when I travel I now use the .99¢ "Alarm Rebel" app. In addition to letting you pick any song from your library as your alarm tune, this app lets you program it to show you the time in cities around the world, your local weather, your personal calendar, and an AP feed. Alarm Rebel is a fairly new app, and before I had it I just used the steps outlined below to have my own songs as my wake up music when I wasn't at home. In order to do this, you'll need to first create ringtone version of the songs. You can do this with one of the many ringtone generators available for free online, or by following these simple steps on iTunes: 1. Right click on the song and select Get Info 2. Go to Options 3. Select the start and stop time of the song trimming it down to under 40 seconds 4. In the iTunes library right click the abbreviated song and select "create AAC version" 5. Drag the AAC version of the song to your desktop 6. Click on the song and change the m4a extension to m4r. It will ask you if you're sure you want to do this; select yes. 7. Delete the AAC version from your iTunes 8. Drag the m4r into the Library tab of your iTunes. 9. The song should now appear in your Ringtones folder. 10. Sync your iPhone. (Please note: If you use a PC there's a possibility you'll have to tweak these steps. I've used them several times on my Macs and made the ringtones within a minute, but I've never experimented with them on a PC.) Ringtones appear under the custom tab of sounds in the iPhone clock application. Just select the one you want to wake up to and you'll be set. : ) ~ skylark Edit - You can also buy ringtones directly from the Clock menu if you wish. Above the Custom tab under the Sound menu, select "Get More Tones" and it will take you to the iTunes store.
How can I use my computer as an alarm clock, as the Windows task planner doesn't allow me to boot an offline computer?
'The task scheduler can wake the computer from sleep.How to Make Your PC Wake From Sleep AutomaticallyIf you need the computer to boot from an off state, you will need a BIOS that supports that. In that case you can usually set a schedule in the BIOS config. However, a 'hibernate' state is equivalent to 'off' from a power consumption point of view, so using the task manager is the best option. In fact, it uses the same BIOS mechanism the the manual configuration does.
My computer clock is skipping time?
Open Date and Time by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Clock, Language, and Region, and then clicking Date and Time. Click the Internet Time tab, and then click Change settings. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation. Click Automatically synchronize with an Internet time server, select a time server, and then click OK.
Why does a computer monitor have a manual adjustment for phase and clock frequency in the monitor settings?
In the bad old days the video cards put out analog signals to an analog CRT. The CRT had no pixels per se, so it didn't need a clock signal, it just continuously displayed whatever analog slewing signal came in.When flat-panel displays came in, there was a problem. The screen has discrete pixels, so the analog signals had to be sampled and digitized. Problem is, there was no clock signal! If the display was sampling the signal at a close but not exact rate it would be sampling the signal some of the time in the middle of each received voltage level, but eventually as it slewed across the signal, it would be sampling in the transition between the values, so you'd get wrong data and funny or fuzzy colors. That's why there were fine adjustments for frequency and phase. The best way to adjust these was to type a long line of |||||||||| characters. If the frequency and phase was just a little bit of, you'd see a moire pattern where a few bars would be okay, but the next few would get fuzzy, then they'd start getting better again. You'd jiggle the frequency control until the good parts got longer and longer until they spanned the whole screen, then you'd adjust the phase so all the bars were sharp, not fuzzy. This is mostly ancient history as most video cards now have digital outputs, now with a clock, so the monitor does not have to guess.
