Tip & How-To about Computers & Internet

Laptop won't power on or stay on?

If your laptop won't power on or stay on for long then follow these quick and easy steps to troubleshoot the problem.

  1. Ensure your battery is holding a charge. Some laptops will automatically shut-off if the battery won't hold a charge. In that case, replace your battery with a new one and retry. Check your charging lights or indicators to see if your laptop is getting power and charging.
  2. Check your AC to DC converter (the little black adapter you plug in your AC outlet.) This converts AC power into DC power. Is it abnormally hot? If so, it is probably burned out. You will need to replace it. Note: High heat is not a true indicator of malfunctioning. It can be dead and cold as well. No power indicators on your laptop could be a sign of a dead or bad converter also. Converters WILL get hot (this is normal.) If it is REAL hot (burning hot when you touch it), then this is not good.
  3. Check your power cord. Are there any nicks, cuts or kinks? If so, unplug it from the AC power and repair with electrical tape or better yet, replace it. Many computer salvage stores carry power adapter cords. They're cheap and could save you from electrical shock.
  4. Check your laptop lid switch. If it is broken or not lit, you may have power but your screen may not come on. This is usually a little button located close to the lid hinge that turns on or off your screen when your lid is open or closed respectively. Normally the operator does not push this button. These are fragile and broken easily on some laptop models. Sometimes these can be repaired, more often they will require replacements. If you aren't an expert repair person, get a technician to repair or replace it for you.
  5. Hard Drive Failure. It could be that your hard drive has failed and therefore preventing your system from booting into Windows. Laptop hard drives can be extremely easy to replace or moderately difficult. The difference lies in how they are accessed. Many older notebooks allow you to replace the hard drive through a single-screw access panel on the bottom of the unit. Other laptops require that you open the entire body, remove the keyboard or the motherboard, really take the whole thing apart. The good thing is that most modern laptops have the easy access.
  6. Display/Video Failure. Connect an external monitor, either a CRT or an LCD, with a standard VGA connector. If your notebook won't light up the external monitor, it's extremely likely that either the motherboard or the internal video adapter (if it's not part of the mainboard) has failed. If the video adapter is a discrete component and you can find a replacement cheaply, it might be worth gambling on replacing, but it's almost never cost effective to replace a mainboard. As stated before, finding a compatible video adapter for your laptop can be extremely difficult to find.
  7. Cooling Failure. Because all the components within a notebook are crammed together for the sake of economy of space, cooling these components is absolutely critical. If you find fans that are crammed full of dust or just plain arn't spinning then I'd suggest a good clean out and replacement of those old noisy fans.
  8. If you have tried these easy solutions and it still won't power on, then your problem lies elsewhere. You may have an internal power switch or voltage regulator problem.
  9. Internal problems will require professional help so go on down to your local PC store and have a qualified technican take a look.
If your laptop is booting but you're getting a message like No Operating System Found or NTLDR is missing then it may be possible that your system has automatically changed your default drive to one that doesn't have an operating system.

This is caused when the computer is attempting to boot from a non-bootable floppy disk/hard drive that contains no operating system or CD-ROM drive. Firstly what you've got to to is press the Delete key multiple times as your computer boots up until it displays the BIOS screen. Then you will need to find the boot disk priority setting. Make sure this is set to your drive that has Windows on it (as priority 1) and not the CD-ROM drive/****** drive or empty hard drive. You can set the CD-ROM/DVD-Rom drive to priority 2 if you like.

Once you have checked that and have set it to your master/primary hard drive (the one that you've installed Windows onto), save and exit the BIOS and on reboot your system should boot into Windows normally.

If you are getting the NTLDR is missing error:

If you've already made sure your boot disk priority is set to your hard drive with your operating system on then see my other tip here: http://www.fixya.com/support/r6845073-ntldr_missing

Hi, I bought Acer4741Z from India on September 2010............now, when i charge the laptop, it shows 52% charging and it wont go till 100 %. Any solution for this............pls help..............


When you first bought the laptop did you fully charge the battery for at least 20-24 hours before use? To ensure the lifespan of your laptop battery is long you will need to follow these easy steps:

1) Charge the battery at least 20 hours before use.
2) Completely drain battery power before you charge it again.
3) Try not to have the laptop battery plugged in if you re going to use AC directly from the wall socket.

You may need to purchase a new battery as this one's lifespan seems to have been reduced as it can only hold 52% charge. When you purchase another follow the above steps.
