Been there, done that....
1) If your battery has a bad cell (18 months normal life) it could cause this. Take the battery out and see if the system works using just the AC power and no battery.
If it works without the battery get a new one and you are good to go.
2) HOWEVER some systems require the battery to be in place to complete the circuit, so you might have to borrow a "good" working battery from someone if my first suggestion does not work.
3) Finally, sometimes the solder connection for the power connection to the motherboard can be broken by mild abuse or stress from the power cord being pulled at an angle. These typically have three solder points and the one on the back is the most likely to fail.
Summary: If #1 and #2 don't work, get a second opinion, specifically in relation to the power connection to the mother board.

I have an ASUS laptop which has been shutting down for the past 1 hour. It has little battery left so I have disconnected pwoer hoping it would go flat.


Asus WHAT laptop?
What is the model number? Bottom of laptop.

Two, is the laptop dirty inside?
If you have never had it cleaned, it is.

Three, "It has little battery left so I have disconnected power......."

Shouldn't have low battery power, if the thing is plugged in.

Four, have you tested the AC adapter's (Charger) output voltage?

Five, is the DC Power Jack in good condition?

[DC Power Jack (DC_IN), is the jack on the laptop that the AC adapter plugs into ]

Could be.........

A) The Battery is older than dirt........
("How old is that battery?
Lemme tell ya,.......that battery is so old that.........")

Battery needs replacing.

B) Power MOSFET's are going south for the winter, and didn't invite you, or the laptop along.

("Pssst..........let's go to the Bermuda's, but xnay on telling the laptop, or dlemaistre)

They control whether the Battery is to have a trickle charge, or full charge; OR, whether the laptop is to just run off of the AC power, and not the Battery.

(Actually the AC adapter {Charger} is a converter. Converts the AC electricity from the home, or business; into DC Voltage.
So it should be stated, ".......OR, whether the laptop is to just run off of DC power from the AC adapter)

Air is used to cool the hardware components inside the laptop.
The two hardware components that give off the most heat, is the Processor (CPU), and graphics chipset. (GPU)

When the Processor overheats it turns off. (BIOS turns it off)
This is a fail safe feature that is built-in.
Keeps the CPU (Processor) from burning up.

So the laptop could be turning off, because the Processor is turning off; due to the laptop is dirty inside.

The battery could be low on charge, because it is old; and not keeping a charge.

OR,
Power MOSFET's are bad, and battery is not being charged up.
Also no power TO motherboard of laptop, because power ends at the DC Power Jack on motherboard; and rest of motherboard isn't receiving power.

Using HP Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's; to explain,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

So,.......
1) Is the laptop dirty inside?

2) Is the Battery more than 2 years old?

3) Does the AC adapter (Charger) prove to be good?
Putting out the required Voltage?

4) If the DC Power Jack on laptop, is the design that has a Center Pin; does the Center Pin move around, when you try to gently move it with a tool?
(BATTERY removed)

I have seen them on checkout aisle racks, at major discount stores.

Dell Studio 1737 with Back lit keyboard but Cap Lock Doesn't Light, replaced Keyboard less than 3 months ago, light worked then and went out just recently.


I'd try a different keyboard and see if the caps light works on that - so you can confirm whether it's the keyboard, or computer.

hiya:) My opinion: If you can get someone to give you a free/cheap estimate of the cost to repair I would do it just to find out, but that computer is getting old and maybe is not worth spending any money on. Unless of course you want to fix it to give it to a younger grandchild and buy the older child a new one. Keep in mind a decent laptop is gonna be 4-600 dollars U.S. hope that helps and good luck:)

NO POWERE UNTIL 4-5 TRYS


Try hooking up only the power supply connector to the motherboard. That way we can rule out whether its a piece of hardware that is shorting out the motherboard.
If the power supply is still acting up then try another known good working power supply. If it turns on like normal then your original power supply is bad. If the power supply still doesn't turn on then you know at that point the motherboard is bad and would need to be replaced.

Acer Aspire 5920 won't turn on, the charger lights up, (bright green) until you plug it into the back of the laptop, then the light goes dim and flashes.still no power to the laptop,not even the fan.


Your power supply or regulator in you laptop has gone south. sorry no quick fix for this one. It needs repaired and would include tracking down soldered connections.

sorry to tell you this.

This could be caused by the processor or fan,But very unlikely to be the mother board.

Laptop went completely dead


Get in touch with Dell again as the replaced part will be under warranty. You can never tell whether a new or second hand motherboard has been fitted, as manufacturers are able to do either when they repair it, so it just may well of failed again.

Wireless Switch


From your description I agree, its probably a damaged switch. I never recommend anyone taking apart a laptop unless they are a mechanical whiz, have experience with laptop disassembly or can afford to break it beyond using. As far as turning the built-in wireless card on without the switch there might be a way. I don?t have a Compaq laptop to experiment with, however, my Dell Latitude BIOS settings has a setting to automatically turn on the wireless card at boot-up. Perhaps yours does too, during your laptops initial boot process get into your BIOS setup menu (press F2 or if that doesn?t work F10 keys). Look for an option relating to your built-in devices or wireless device. My Dell setting is fairly ovious: "Turn on wireless device". If you find a simliar option turn it on, reboot and look for the wireless adaptor. Another option may be to buy an inexpensive UPS wireless adaptor. You can pick them up on Ebay for around $30, not as spiffy as the built-in but probably a lot cheaper than paying a repair shop to fix a three year old laptop. Good luck.
