Dell 1749 won't boot power light flashes 3 times


You've got an issue with your Memory or the Video Card.

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Remove the battery, Remove the cover that houses the memory then remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

My HP Pavilion dv9740us Notebook PC dosent start the screen is black


Doesn't start as in nothing happens when you hit the power button? Or are you saying the Desktop is black, but it seems like windows started and went through the boot process?

If nothing happens when you hit the power button:
Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

Toshiba satellitep205d-s7438 won't boot up


You need to be more specific and tell what happens when you plug in the power cord and press the power button. There are a number of reason why a computer will not boot, but if you tell what's going on someone can help you.

Computers don't boot for basically the following reasons, 1) the power supply is bad. That means when you plug it in you don't see any lights, and when you press the power button nothing happens, you hear no fans, no beeps, no blinking lights, no hard drive spinning, no cd drive clicking and nothing appears on the lcd screen.

2) A motherboard issue, usually when this happens you will either see blinking lights or hear beeps. Those blinking lights and beeps are codes that tell the technician what is really going on.

3) Static Buildup - try removing the battery and the power cord then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back in (leave the battery out) and Press the Power Button. If it boots up you had static buildup and can replace the battery, count your blessings and Thank The Lord cuz a dishonest repairman would have told you he had to replace the motherboard for $300

My hp2133 is showing a black screen when ever i am turning it on now ............the screen to totally black and it shows nothing .


The screen is not getting power, the failure of the flexible cord to the lcd screen can also be a possibility. Also the power supply section could have failed thereby faulting the screen.
Hence you will need to check on all these sections of the mother board to confirm the issue.
Get help if technically not experienced.

Try the battery removal/re-install approach. remove battery, hold power sw down for 40 seconds with power cord connected; replace battery. Works for me.

Similar problem here...Lenovo T61p won't power up.


Sounds like it needs the magic reset procedure. Press the power button 11 times and on the 11th time hold it for 30 seconds. Put the battery and power adapter in and retry it.

Year old advent netbook 4211b will not turn on,


When you press power button press F1 or F2 or "del" key if you can see bios screen then you not need to refix RAM memory or reset bios.
IF you can see bios screen then lake sure harddisk is detected and SATA is disable then save settings and exit.
Also when you power up press F8 key if you able to see safe mode and other menu then you have change screen resolution enter in enable vga mode.
Then open control panel and display then change scree resolution to 1024*768.
Then apply and ok.
But if you can't see bios screen or nothing in dispaly then you have to refix RAM memory .
Check in back side there is 1 plate open it then refix RAM memory.
If still not get display then open back cover of laptop then find motherbord on it then pull cmos cell for 10 minutes so all settings go to defaults then again refix cmos cell then check.

Let me know if you need more assistance.
Thanks.
