Try a different keyboard?
If it's getting that far it appears to've POSTed correctly.
3x12=36
2x12=24
1x12=12
0x12=18

ermmm... it is not the same computer I'm using to write those messages... 
Nevertheless I've found what happened... the battery died, the date of the system was resetted and therefore the OS did not started.

I never said it was. This:
Joan Murt wrote: The computer can't go further the bios message telling me that I should press F1 to continue as the BIOS has detected some changes (not specified).
If I press F1 nothing happens.
Only occurs after the POST is completed.

I've never heard of a system not letting you into the BIOS or an OS boot failing because the battery was dead before.

Me neither... it is amazing: the user told me that nothing happened this morning... after sitting in front of the computer and pressing F1 to continue after a warning telling me that the battery was dead... the Windows loading bar appeared and after that the mouse cursor on a black background. the fact is that nothing else happened... I've restarted a couple of times the computer and the same happened each time... After that, I've entered the bios and set the correct time and date and then all was back to normal... 
Who knows why but it works...

Its a feature...

Its not big, and didnt take long to develope, but its complicated enough. But not a single BSOD during the entire dev test process and its functionally 100% too. (Smug satisfied smile time  )
Thats what 15 years experience gives and what the client pays for. (Even bigger smug smile. )

A friend of mine who bought a second-hand LG V1 Express Dual Laptop, has asked me to reinstall the OS because there was a boot problem. I tried installing Windows 98, Windows XP, Windows Vista and Windows Seven. Any OS can be installed, but there is no audio output. All attempts of automatic updating of drivers failed.
However, when I boot with an Ubuntu Live CD (even without installing), I can here the logging-on sound. Could anyone help me find the necessary drivers or fix the problem in some other way...?

Do you see the device within the device manager or no? If you see an item with a question mark, that's usually indicative that the system can't find the right driver, if its there, the problem may be something else (although it may also have picked the wrong driver).
There's programs that allow you to scan the system to identify the hardware installed (this is one I've used)...
http://download.cnet.com/Unknown-Device-Identifier/3000-2086_4-42618.html?tag=mncol;1[^]
Once you've identified the hardware, go to the manufacturer's website to find the appropriate driver.

|
|
|
|
first go to the device drive:
there is a icon there like a speaker
heres your gonna do:
1. if there is a yellow question mark then it indicates that there are no drivers for your sound output or your driver is not compatible with your laptop
try to install the driver. there are lots of site to get the driver of your laptop
here!
2. try downloading universal sound driver.
there are lots of it on google
Unless your built in speaker is broken

Hi,
I am computer science student and i want to control the room lights via sms sent from remote mobile through gsm modem AT commands send to PC and is further forwarded to microcontroller ATMEGA8 but i donot have any idea how to start with.Can any one give me some circuit diagram based on this microcontroller circuit for controlling room lights through commands sent from pc to microcontroller. I want to connect microcontroller with PC via RS232. For the time being i just want to control one light using one relay. I shall be really thankful if anyone can send me the circuit diagram.
Thanks for help in advance.

There are a number of articles on such subjects here at CodeProject.
Have a look at these[^] and these[^].

Send the SMS to the girlfriend and get her to turn the lights off?

How about just sending message to your pc via cellphone then your pc will process it (programming) and send output through parallel port or com port.
that should do it.
we created it last year via VB 6 
|
|
|
|

Yes thats what i want to do this via parallel port and i have come to know that it can be done through relays without using microcontroller?? Is it possible?? Can you send me the circuit diagram for that? Here is the link also:
http://michael.hinespot.net/circuit.php
Can i use the circuit diagram described in above tutorial?

my fault as i recall i connect my cellphone(3310) to my PC (parallel port)[i think i dont use any PIC i just use the nokia cable CP tp PC] then when i text that cellphone the text will appear on Visual basic textbox then my output goes to my parallel port as well
first you need to know the pin config of parallel port(output and input)
WATCH TUTORIAL
im still finding the site where i get the schematics
but it is possible

There are many ways to accomplish this:
1. Using a PC and a phone (connected with serial cable).
2. Using a microcontroller and a phone or GSM module.
3. Using PC and microcontroller and phone.
Obviously the third option is redundant.
Now regarding the which way to go (option 1 or 2) this depends if:
1. You know how to program embedded systems (and you know the flow of programming ATmega) or you want to learn.
2. You are an experienced PC (Windows/Linux) programmer.
As i am building embedded systems for many years i can provide you some info for the first option.
1. You can directly connect the phone to ATmega using the UART (of AVR). The phones normally have TTL logic level output for their serial port (and this is why you might need a level translator to RS-232 levels if you connect the phone to PC Serial port). Unless your phone provides a USB only connection (and this depends from the phone manufacturer and model) you can connect the ATmega to the Phone through the TTL serial port. I believe most elder phones have serial TTL interface.
2. The microcontroller have to drive the Relay(s).In the following link you can find way to do it (btw you will need similiar circuits if you drive from the parallel port):
http://www.scienceprog.com/drive-relay-with-avr-microcontroller/[^]
3. You have to write the software on ATmega (obviously) to control the phone (i believe AT commands) get the messages and activate accordingly the relays. If it is of any help to you i have a relative article for a simple non-preemptive OS for AVR that you can use as platform to begin building your application.
AVRILOS: A simple OS for AVR microcontrollers[^]
Hope this helps.

nice article. I hope she found what shes looking for. There is so many in the web the problem is how you interact them to pc. You must know the data receiver of CP , its data sent as well as in PC.
Good Job Bro!

it is an cmplicated one but i think so far ..it has some sollution..such as...plc device..the plc device has two logic gates...1 and 0....now you have to think that how my call ..or mabile call will give an instruction of 1 and 0...so i think that transducer which can be installed at the end can solove this problem....pc is used ....

I am building a replacement home/office server for a small software company. The server functions as a print server/web server (internet and intranet)/file server/sql server. Currently, the OS (2003) and other files are only using about 38 GB. I have a 64 GB Patriot SSD that I had planned on putting everything on. (Server 2008 r2, SQL Server 2008, etc.) I also have a Seagate Barracuda 1TB 7200 drive that I was going to use for system backups and sql log files. Other hardware in the new build are a AMD Phenom II X4 955 (3.2 GHz) and 8 GB DDR3 RAM. Most of the SQL databases are used for web reporting applications for yearly data, and so are mostly read heavy. (at least 90%) I have searched for information on best practices for using SSDs in production servers, but can't find enough information to make a decision on where to best implement the SSD in this scenario...as the main drive with the OS and applications, or as a secondary drive for only certain things like sql data files, web resources, etc. I am open to any suggestions. Thank You

Thanks, I did see that article, which left me more confused than before. I went ahead with my initial plan and put the OS and apps on the SSD. Aftert installing SQL Server 2008 and Crystal Reports XI, I still have over 36 GB left over. SQL Server log files (including tempdb) are located on the secondary drive, as are all development files, database backups, system restore image, documents, etc. All in all, this was a very boring build...I spent more time planning it than it took to put together. Everything worked the very first time. It seems to be a very speedy system, from POST to desktop in less than 10 seconds. (not counting typing the login)

Yes, I usually hear good things like that about SSD; the article I mentioned was the first negative I saw. You should report back in 12 months or so...
Good luck.
