Charger problem
The powerpack/charger for my Inspiron laptop is giving me problems and I wondered if anyone knows anything about these? When it's plugged into the laptop the charger doesn't always turn on, the small led somtimes doesn't iluminate and there's been the odd 'bleeping' sound coming from it. We got the laptop last xmas.

Charger problem
if it is less than a year old then call dell for troubleshooting and/or
replacement. almost all of their laptops have at least a 1 year warranty (a handful were just 90 day). support.dell.com is a good place to start, and you can use telephone, online chat, or email. online chat is probably the most efficient, but if it is a lattitude then i would call on the phone.

Charger problem
Hi!
The powerpack/charger for my Inspiron laptop is giving me problems and I wondered if anyone knows anything about these? When it's plugged into the laptop the charger doesn't always turn on, the small led sometimes doesn't illuminate and there's been the odd 'bleeping' sound coming from it. We got the laptop last xmas. Does this only happen when the laptop is plugged in? If so, does it still happen when you remove the battery with the system plugged in to the adapter? The noise you are hearing is the protection circuit in the power adapter shutting down in the presence of an excessive load or short circuit. Only some of these circuits will "latch" and stay turned off after a fault, so the unit ends up cycling. A very common problem with these is a broken wire in the cable. There are a couple of ways to find this: 1. Plug the power supply in, connect a voltage meter to the output, and flex the cable. Watch the meter while you do this. Any major movement of the needle or large swings in voltage indicate a break in the cable. 2. Plug the power supply in and just wiggle the cable to see if you can make it cycle. 3. Carefully inspect the cable for bulging, cuts, exposed wiring (what you see is usually a braid poking out) or signs of stress. 4. Try the adapter with a known working computer. If the fault only takes place when the adapter is plugged in to the computer, and it passes these other checks, the computer is most likely at fault and has an internal problem. If you need to replace the adapter, a genuine Dell adapter or something from a well-established brand name is your best bet. Cheap or "no-name" generic replacements may not work properly with your computer. William |

J The computer industry has a poorly publicized horror story about the weak attachment of the connectors for A/C adapters (chargers) to laptop motherboards. They are all soldered to the motherboard without anything else to hold them firmly in place. Solder is a soft metal and the soldered connections to the motherboard eventually fracture, leaving either a sporadic connection between adapter and motherboard or no connection at all. In the latter situation, the battery never gets recharged and eventually the laptop stops working. It does not matter which brand of laptop it is, and whether the model of laptop is "high-end" (usually due to marketing hype) or cheap. The connectors are almost universally soldered on. HP got nailed with a class-action lawsuit on this in recent memory, and so did Dell. The Dell lawsuit was limited to Inspiron 5100 or 5150 laptops and was settled by extending the warranty period on this model for one year. My fear is that the power connector on your laptop is coming undone from the motherboard, given the symptoms you describe... Ben Myers |
