Specs: Windows xp
I have an Acer Aspire 1640 which is not booting. When i press the power button all lights gets lit, but within 15 sec, the hard disk light stops. Monitor remains blank, not even the bios screen comes up. I tried to boot from cd by putting windows xp cd, all i could hear was the sound of loading the cd. Monitor remains blank. Please help me to boot the machine. I dont have any CD's with me except the Win XP CD.

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.

Some laptops will display on an external monitor without you having to do anything.
NOTE that I know that applies to newer Acer models.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / sometimes both / built in display video only - see the Owner's or User's manual for the model.

If there is nothing wrong with your AC adapter or it's connection and the jack in the laptop.......

Laptop main batteries usually work as they should for a year or so, then they begin to rapidly deteriorate. From what I've seen, by two years they cannot be charged to anywhere near their full capacity, and it gets worse after that.
They often develop internal shorts when they are older. If the battery gets HOT rather than just warm after you have attempted to charge it for at least a half hour, or after you have been using the laptop for a while with the AC adapter plugged in, it's definitely internally shorted and you must replace it. Internally shorted batteries getting too hot have been known to cause the laptop to catch on fire.

Tips about battery charging problems on Dell laptops - may apply to other makes.

Flashing the bios IS NOT A FIX-ALL !

It makes no sense at all to flash your bios if the computer was working fine previously with the same bios version, same cpu - in that case, your problems have NOTHING to do with the present bios version.

No video on the built in screen on a laptop, or problems related to the main battery or charging of it, are VERY COMMON with laptops that have had a lot of use !

I know this thread may well be old but i feel it necessary to post my thoughts.

There are several possibilities for your error.

Faulty battery? - Remove the battery and attempt to boot again, you wouldn't believe how many laptops have this problem.

Faulty BIOS - Use an external usb floppy drive with the latest BIOS on to flash it press the Fn + Esc keys. Please search for instructions online they are available.

Faulty CPU - a new CPU for your laptop is approximately £12 and is very easy to change for a moderately skilled technician.

Faulty Motherboard - Replacements floating about on ebay for approximately £30, again not an extremely hard job for a skilled technician.

Remove/Replace BIOS Battery - Remove the CR2032 battery under your centre cover for about 5 minutes and then replace, turn the laptop on without the main battery installed and as its powering on keep your finger on the power button and remove the power jack. Hold the power button down for 1min and then replace the power jack and this will clear system static.

Best of luck, many more fixes available but considering the laptop age it becomes not worth doing. ie screens etc.
