Ive got the Samsung R519, just bought a new battery for it but doesnt seem to have made a great deal of difference, its only 2yrs old! Wont turn on when on adapter & battery removed & no charging...


From the description you have motherboard issues, sub out the ram memory one at a time to see if you can get it started, no change! the dc jack in the laptop is a common source of trouble from no power to intermittent operation, at this point the laptop will need to be taken apart for further examination.

My c610 battery i have replaced it 2 times but it still dolesnt charges it stops it stops to charge during charging


Hi nabhanizatio

DELL LATITUDE C610 BATTERY CHARGE FAILURE

The likely cause of the original battery fault is a very common mistake in the way laptops are used. A laptop battery, working at optimum efficiency, whether of the older Nickel Cadmium and Nickel Metal Hydride or newer Lithium Ion types, is meant to charge under power and then discharge under use, if it is to have a long and useful life. This means that it should be used in a similar way to a cellphone's battery - connected to mains electricity and charged up when low or flat and then disconnected from the power and used on battery power alone until the power level means the cycle needs repeating. Many people, however, unwittingly use their laptops like desktop PCs and leave the mains electricity permanently connected to it even after the battery is fully charged. The reason that people cite for doing this is 'convenience'. This, however, is a mistake.

Laptops have more flexibility than cellphones in that, if they are mainly used in one place rather than as mobile devices, then it is possible to charge the battery to full capacity, disconnect from the mains, then remove and keep the battery until the next time the laptop's mobility function is required (periodically recharge the stored battery if not in use for long periods of time because the charge slowly dissipates when not in use), reconnect the mains to the battery-less laptop and use it like that, ad infinitum.

When a laptop battery is fully charged, what it really wants to do is discharge. However, maintaining the mains connection prevents it from doing so. The Power Management
System on the motherboard is designed to cope with long periods of either battery powered or battery-less mains powered use, but not long periods of simultaneous battery + mains powered use. A fully charged battery still connected to mains electricity has no means of discharging and various power sensitive components such as the Power Inverter, Cold Cathode Backlight, LCD Panel, Graphics Chip and Motherboard Power Management Stystem can become damaged by the power bottleneck created.

Using the battery in this wrong way also gradually depletes the charging capacity of the cells, until eventually, the cells can carry no charge, meaning a dead battery. A dead battery, where the cells are depleted, left in the laptop with the mains connected, is even worse for the Power Managent System
because the flow of power to the motherboard via the dead battery cells is inefficient and intermittent, creating battery overheating, low CPU Cooling Fan speed, inferior cooling and consequent internal overheating hazards in addition to potential electrical damage to several components. When damage to the Motherboard Power Management System passes a certain point, even a new battery might not charge - the situation in which you now find yourself.

Loose DC jacks, leading to intermittent power drops and surges, are typically caused by the jack being allowed to take the weight of the heavy transformer box on the laptop's power cable. The solution is to ensure that the laptop is never held, carried or used with the transformer hanging unsupported. If the laptop is in use, the transformer should be disconnected, carried, placed on a desk or table near the laptop (if the cord is short) or laid completely full-weight-flat on the floor (if the cord is long enough). Also, a Surge Suppressor/Surge Protector should always be used between the mains power socket and all computer
equipment, rather than directly to the mains.

If either the Motherboard Power Management System or DC Jack are ever damaged, your laptop would require professional specialist repair by a Component Level Laptop Repair Specialist, providing No Fix No Fee, Warrantied Repairs ( typically 3-6 months Repair Warranty).

I hope this helps.

Since last two three days my laptop's, em350, battery charge indicator won't turn blue after three hours. Please help!


Hello.

The most common reasons for power issues are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

Hi, I really need some help. I want to know whats wrong before taking my hp pavllion dv600 to service centre. Problem is that the charger doesn?t charge the battery at all. Charger is fine with other...


If the power supply does not run the laptop without the battery, then the problem is the jack in the laptop, over time the plug breaks free of the motherboard causing intermittent operation or no power. If the power supply runs the laptop without the battery, it is the charging circuits on the motherboard that is the issue.

Advent N270 netbook will not charge. Orange light comes on initially then goes off. Also when I wiggle the plug into the laptop the light flashes on and intermittently.


It sounds like either a bad connection on the motherboard or a broken wire in the adapter making intermittent connection.

1. With the power adapter disconnected, do you have a power light? This would indicate the adapter is good and the plug is questionable.

2. Check your power adapter output with a multi-meter.(be sure to wiggle the wires around) If the power fluctuates, replace the plug.

3. If the power is solid, replace the motherboard connector.

Faulty charger point.when i plug charger in i have 2 keep still other keeps going off


If the charger jack on your laptop gives you intermittent connection, the changes are that it needs to be replaced. If you are good at soldering on PC boards you can replace it yourself. if you take it to a repair shop they will probably charge you about $90 to replace the jack.
If you want to consider replacing it yourself, take a look at

You can Google "laptop power jack repair" for more information and service sites.
Hope this helps.

My inspiron 1525 is not charging. Have replaced battery and charging lead and still does not charge.


Based on what you have stated, you replaced the battery and charging lead but the laptop still won't charge. What do you mean by charging lead?
Are you referring to the power adapter?

Since you already changed those two things, then the problem could be the power jack of the laptop and/or the connections inside the laptop.

Try to plug the power adapter slowly and try to wiggle it. It you feel that the power jack is wiggling, then the problem is a loose power jack that is why it won't charge. And you need to have a tech tighten that up for you.

Have a great day!

Screen flickers on Acer Aspire A150 Netbook


Hello,

It really sounds like you have a short in the ac adapter. Laptops dim the backlight on the screen when on battery power and go full brightness when on AC. I think your adapter is going on and off. When it is on the screen is on full and when it goes off the screen dims down a bit. You could have a bad adapter, most likely, or a bad charging jack in your laptop. Check the adapter first, just use a multimeter set to voltage. Read lead goes to the center pin and black lead goes to the outside metal contact, you should get a reading of 18 to about 26 volts. Move the wire around near the plug that you are holding and keep checking the readout. I think you will find the voltage dropping as you move the wire.

I hope this helps, If so please rate my solution.

Yup... find a reliable electronics tech to resolder/ solder in a new power jack.. Replacement jacks all over ebay.. not too hard, but you need good equipment and a steady hand.. Pay about $50-$100
