Question about HP Hewlett Packard Compaq 6720s Laptop Computer - Intel Core 2 Duo T5270 1.4GHz, 802.11a/b/g Wireless, 2GB DDR2, 160 PC Notebook

1 Answer

Laptop sometimes switches off when moved.

Loose connection? Overheating? Laptop runs off mains power however battery still holds charge so if loose connection between say power jack and motherboard would power not still come from battery? Other info:- running windows vista home basic/ unit around 4 yrs old/ new power jack fitted around 18 months ago - no problems until about a month ago. Base of laptop around power jack area and back of screen at bottom very hot (this has always been the case even when laptop was new - problem disappeared for around 6 months after new jack fitted but then returned) Have tried different power adapters to confirm not causing problem. Doesn't seem to be caused by running any particular program. Fully checked for viruses etc..

Sounds like a loose connection where the laptop opens and closes hinge there are wires that run from the main screen to the main board. If you know how to take the unit apart it maybe a cheap fix if not then a new laptop maybe the way to go the prices have really dropped from 4 years ago

lala linda is right. . . repairing the power pin isn't that expensive ... In fact I've fixed some myself and it's really not that hard. It is time consuming and tedious to make sure that all the bits and pieces fo back in the right place. Take some pix as you take it apart and you will find that's it much easier when you go to re-assemble the unit. btw . . . The power pins are available on the net for $ 10 or less usually.

Also . . .Once you get it fixed get a Cable retention device to make sure you don't damage the pin a second time. Personally I recommend (and use) this one.

I would suggest replacing your battery pack there must be something shorted in it. Don't try to use it anymore or you might face a lot of trouble in your laptop in the future.
Good Day.

Chances are the batter is bad. Did you just purchase the notebook? You may want to try swapping the battery in your laptop with the other laptop you tested the adapter on. If you do need a new battery, here is a link

Gets no power from wall or battery


Few things in life are as frustrating and infuriating as working ******* your laptop, only to see the screen go dark due to a sudden power loss. While there's a good chance your hard work and data is gone, the more concerning issue involves the cause of the sudden loss of laptop power. A suddenly dead laptop could indicate a more serious problem, or simply be due to a loose battery or power cord.

Overheating

If your laptop's fan was running hard and fast right before your laptop went dead, it's possible the machine shut itself down to avoid damage from overheating. The internal electronic components of a laptop generate heat when the computer is turned on, and this heat must vent to avoid causing damage to the machine. If the air vents are clogged or blocked and the heat inside cannot dissipate, the laptop will power down without warning to prevent possible damage. To avoid this problem, ensure that your laptop's fans and air vents are clean and clear, or use a laptop cooling stand to help vent the heat.
Battery Issues

Laptop batteries are not exempt from malfunctions, and a sudden power loss may point to a problematic battery. A loose connection may cause a surprise laptop death, as can dirty connectors. Like most other battery types, laptop batteries are not immortal and eventually lose the ability to hold a charge for long. Some laptops have sensors and circuitry to monitor the battery, and will cut power to and from it should it become too hot or exhibit too high a current. Try cleaning the connectors and reseating the battery properly to fix the problem. In the event of a loose connection, a repair technician may be your best course. For malfunctioning batteries, a new replacement battery may be the best way to prevent future power failures.
Electrical Problems

If you were using your AC adapter for power right before your laptop powered off, there may be an electrical problem somewhere along the line. The outlet you were plugged into may have short circuited, or the adapter itself may have overloaded. The connector on the back of your laptop may be loose, preventing proper connection of the adapter. A short circuit within the laptop itself may have occurred, preventing either the battery or adapter from providing power to the rest of the electronics. Work backwards to find the source of the power supply problem. Try a different electronic device in the outlet, and insert the adapter itself into a different outlet. Reinsert the various cord ends into the adapter and laptop to ensure a tight connection. If a short circuit seems the likely cause, seek the help of a professional technician for repair.
Troubleshooting

Try to ascertain what occurred right before the power loss. A physical move of the laptop may have loosened the battery or jostled the adapter cord loose. Try removing and then reseating the battery and tightening the adapter cord. A loud fan noise may indicate that the machine was on the verge of overheating. Let the machine cool completely before attempting to reboot. An unusual noise emanating from within your laptop may indicate a short circuit. A beverage spill can cause the death of an laptop if not attended to quickly, causing short circuits and power failure.
Precautions

Observe standard safety procedures when dealing with electricity, and never disassemble or examine an outlet or your laptop without disconnecting all power first. If delving into your laptop to check for short circuits and loose connections, work in a clean, open area to avoid introducing any new contaminants to your laptop's vulnerable interior.

Gateway kav60 not charging. i have to wiggle the cord and sometimes it refuses to charge.


I guess you've got a broken laptop power dc jack or power cable.


Symptoms of a broken Laptop DC power jack:


- The laptop only operates when you hold the DC power plug in a certain direction (DC jack is broken or loose).
- The laptop only runs on battery power (no power is getting through the DC jack).
- The laptop gets no power at all.
- The laptop will not charge the battery.
- The laptop switches from AC power to battery power intermittently due to a loose or broken power jack.
- The laptop suddenly shuts off.
- The DC jack may feel loose.
- Sparks come out of the back of the laptop when you insert the power plug into the DC jack.

If you wiggle the connection to the laptop and it feels a bit loose, then the power connection on the laptop itself probably needs re-soldering. This is a common problem with laptops. Unfortunately unless you can do it yourself or know someone you can, then it will cost quite a bit to get fixed outside of warranty.

My computer shuts off randomly by itself sometimes


Shut-downs can be caused for "all manner of reasons" (including overheating).
The cause of over heating can be due to
1) fault in power supply.change the power supply.
2) Any of the internal wire connections are got loose.so turn of your computer.then unplug it from main power outlet.then remove all the exaternal wires connected to the computer.then if its laptop open the back of the laptop and check out internally if any wire of hard disk,power supply is got loose.if its proper then also remove the wire and reconnect it.but if its normal cpu and not laptop then open the cpu by removing screws and diconnect all wires and reconnect it again.then connect all the external wires as it were before and check out.
3) if its laptop then it can also be the battery issue.if the battery is not charged then also this can happen.in some cases battery is fauty so it shows its charged but actually not charged.so replace the battery and check out.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

If your power adapter is still putting out the correct voltage when it is plugged into the wall, then you can safely assume that the adapter connection on the motherboard has come loose.
It can be replaced, but it is sort of tricky. You are probably looking at buying a new motherboard.

The DC connect on the system board may be loose. Take hold of it at the connection and wiggle it slightly. If it moves alot, the DC connector on the board is loose.

If not, take your battery out and power up the unit and see it stays on. If it does then it is the battery.

Acer laptop power problem


Does not switch on from mains.?????????????
PLEASE EXPLAIN..........

Is the laptop lights not coming on when you plug it in? If not refer to the following.

Are you sure that your power plug has not broken loose. You will have to take the laptop apart to find this out. Sometimes the solder joint will come loose. Do not take this laptop apart unless you know what you are doing. The manual can give you step by step directions sometimes. It is not easy to take it apart without breaking the little things. If you do take it apart, take pictures of every step and take notes and even draw picture so you will know where everything goes. You can touch the plug where it is soldered and re-solder the plug. Please be careful. This takes someone with good solder skills to do.
