A Dell Mini net book is a small and very portable laptop. The compact size makes it a good candidate for travel or just simply using around the house. Outdoor aficionados can get the most computing life out of a Dell Mini by finding a way to charge the battery outside. One method works when you are near a building while the other can be used for more remote outdoor locales

Things You'll Need

  • Extension cord
  • Solar laptop charger
  • Dell Mini power adapter

    • 1 Plug an extension cord into an available power outlet. Run the extension cord to where you are outside. Many homes also have exterior outlets. Use an extension cord that is designed for outside use. Plug the Dell Mini power adapter into the extension cord to charge the battery.
    • 2 Purchase a laptop solar charger. Solar chargers are available from several different manufacturers and may come in the form of a roll or be built into a case that closes up for travel. Depending on the charger, you may also need to purchase a Dell Mini power adapter. Some chargers work with a Dell Mini cigarette lighter adapter that is designed to plug into a vehicle's power port.
    • 3 Place the solar laptop charger in a sunny location. Open up the case if the charger is in one and roll it out flat or unfold it to expose all of the solar cells.
    • 4 Connect the Dell Mini power adapter to the power port on the solar charger. Connect the other end to the netbook. The adapter will regulate the charge coming from the solar panel and recharge the battery in the Dell Mini.
  1. Tips & Warnings
  2. Solar chargers offer less power than a wall outlet. They can be used to extend the battery life of a Dell Mini or to recharge the battery when the netbook is off.
  3. Some solar laptop chargers are relatively heavy. Take the weight into consideration if you are going to be backpacking or otherwise carrying it on your person.

No power light showing cannot use laptop


First, find someone who has a charger that will fit yours and try that; sometimes the wall chargers go bad or tips get bent (even though they don't look bad).
Second, if that does not work, you may need to replace the power jack within (I just did that on a Dell Inspiron 1545 for a relative), part was about $10 bucks.
In the case of the one I did, both parts for bent and bad so I replaced both.

Xps 17 battery charger


I think either you have the wrong DC Power Jack installed (where the power cord plugs into the computer) or the wrong AC Adapter & Power Cord.

Hopefully you have an AC Adapter Power Cord that was made for your computer and not one of those one size fits all that some stores sell with the interchangeable tip at the end that plugs into the computer.

If you can identify what the battery / laptop power requirements are, then you can buy replacement 'universal' laptop power supply / charger units which come with a selection of different standard connectors to plug the charger into the laptop.
Amazon sell a Sumvision Universal Laptop AC Charger Adapter which is available in different power output wattages (95V 120W).

Hi, what your toshiba laptop model and asus laptop model? You can use the asus ac adapter on your toshiba laptop only if the folllowing three conditions are met:
1) Output Voltage is within +/- 5% of your old charger's output.

For example, if your old charger provides 19V, then you can use a charger that provides 20.5V or 18.5V.

2) Output Current is the same or higher than that of your old charger.

For example, if your original adapter provides 3.42 Amps, then you can use a charger that provides 3.42 Amps, 3.9 Amps or higher.

3) Connector tip must fit securely into your laptop.

For the specifications of the two adapters, you may check it here:

If you are using a Genuine Dell charger, the battery should charge. I don't think its the battery however. My guess would be that there is damage to the inner pin of the charger jack, or possibly damage to the socket where it fits. It could also be down to worn contacts. The charger will power the laptop, as long as there is sufficient contact on the + (inner pin) and a tight enough fit on the outer (-) contact.

If you look closely at the inner pin on the charger, check and see if the inner pin has snapped.

The best check is to obtain or borrow a known good dell charger (aftermarket ones will simply not charge the battery) and see if that resolves the problem, or if you know anyone with the same model, ask them to see if their laptop will charge the battery. That at least will either confirm or deny the fault being with the charger or battery.

More serious is the possibility that the charging circuit has failed. On occasions, the small fuse on the motherboard can fail, or, there is a more deep seated problem on the charging circuit.

Replacing the OEM 18.5 V 3.5 A ac adapter with an 19V 4.74 A adapter for my c551nr compaq, should not give me problems, will it? It should be within spec, hopefully.


Specification of Compaq Presario C551NR AC Adapter:
Power: 65W
Output: DC18.5V 3.5A
DC Connecter (Barrel) :
Internal Diameter: 1.7mm
External Diameter: 4.8mm

But it's OK to use a 90w 19V 4.74A adapter on your laptop only if the connector tip fits your laptop.

Thefollowing three conditions should be met for you to use an ac adpater safely. 1)Output Voltage is within +/- 5% of your old charger's output.
For example, ifyour old charger provides 19.5V, then you can use a charger that provides 20.5Vor 18.5V.
2) Output Current is the same or higher than that of your old charger.
For example, ifyour original adapter provides 3.42 Amps, then you can use a charger thatprovides 3.42 Amps, 3.9 Amps or higher.
3) Connector tip must fit securely into your laptop.
