Make sure that battary is charged , the blinking leds in some laptops is usually a sign for empty battary.

SOURCE: Acer One 1542 series not boot

Hi,
Take out the battery and the mains power, turn the laptop over and remove the ram cover, look for the ram and take it out by pushing the metal lugs outwards so the memory pops up, it's now ready to remove, the ram (memory) looks like this >>>>>>

Once the memory is out look very close in the memory bay for 2 brass triangles, they will be in the shape of a diamond, get a flat head screwdriver and short them 2 pins out, this will clear the CMOS, put the memory back in, turn the laptop over and plug in power & hit the on/off button.
When it comes it will say that bios settings are wrong so go into the bios and set the time and date, save the changes and exit the bios, the computer will restart and hopefully boot up with no more problems.

Hope this helps.

Good luck.

So there is your screen resolution issue.
For that when you power up the laptop press continue F8 key then enter in "Enable vga mode " then go to control panel and display proeprty then go to settings then change screen resolution to 1024*768 then apply then restart then check .
If you cannot able to see safe mode and other menu whne you press F8 then your Dispaly has hardware issue because your motherbord working fine it gives dispaly proeprly to vga.
If you have vga port on laptop and you have other external monitor you can check it.
Connect your monitor to vga port then if it gives diaplay then some rong with your Laptop internel dispaly screen and if it is in warrenty you can use warrenty they repalced or repair your screen.

What would be the probable cause of a sony vaio fs830/w of starting up & the 3 green leds on top stayed lit


You were FORMATTING it? Meaning... you were erasing the operating system? If that's the case, then... you have no operating system and the computer cannot boot up because it has no operating system to boot into.

My eee intel will turn on but the screen is black and the power lights will come on to when you turn it off it flashes white and thats it!Can someone help me please,


It'd be a good idea to check if the laptop is actually booting up or not getting anywhere at all. You can check this two ways, fairly accurately.

First of all, the best way to check is to plug your laptop into another external monitor, you should be able to do this with the VGA connector on the left side of your laptop. You can do this with any monitor that's used with a PC. See if the monitor turns on when the laptop starts.

If you don't have an external monitor to try, the numlock, caps lock and scroll lock keys on your keyboard should show that they're active by the LED that shows they're on or not. Turn it on and let it boot up (give it a few seconds or minutes to be sure), then press numlock or caps lock or scroll lock and see if the LEDs for those keys turn on or not.

If the external monitor works, or the LEDs are functioning as normal, it's likely that the monitor has a loose connection inside or that the monitor is entirely broken. Since the monitor is flashing white when you turn the laptop off, it would sound to me that the inbuilt monitor is connected but not working.

If the external monitor doesn't work, and the LEDs for capslock etc don't respond, then it's likely that something else is wrong with the laptop entirely.

It will be helpful to know what happens to narrow down additional help.

Whenever I press the NumLock button, it does a sticky key-type beep and the green LED comes on but I am unable to use the keypad still. The same thing happens with the CapsLock key but I am able to use...


Hello
In control panel/keybaords. Disable sticky keys.

Or clean the keyboard with some windex and a rag,try turning it upside down and lightly tapping it to remove dust and dirt.
