    thanks for your reply no_ky
    Sorry i didn't write these details.

    It wont start by removing the battery either. no lights except the adapter round light.
    I already checked for the recall with HP about the battery.
    I checked charger zas well with volt meter, works fine.

    As far as BIOS is concerned, i did an update about 2 months ago, and now i haven't had any chance to turn it on to do it again unless i charge my battery somewhere else. i am gonna try that tommorrow in a store.

Check your the version of the current BIOS. You may need to update the BIOS, HP has solve battery wont charge problem in BIOS.

  1. Shut down the laptop with the battery in and plugged in.
  2. Remove the battery.
  3. Reboot the machine.
  4. Wait for Vista to come up and show the power icon.
  5. Reinstall the battery.
Your battery could just be dead. There are a finite number of cycles that any rechargeable battery can endure and getting more than a year's worth of charges is simply a blessing. Count on needing to replace it once a year (mine's been going strong for almost 3 years now oddly enuff). That said, the battery could still be fine and your charger could be the issue. Any breaks or pinches in the line? Also, check the HP supprt site for battery recalls. It's possible you have a unit that has been affected by one of the recalls. Get the battery info off your battery first and then look it up online to see if you might qualify for a new free replacement battery

My laptop won't turn on. I tried taking out the battery, a different battery, a differnet power cord. It won't turn on. Is there a way to reset it?

Are there any lights or indications on the battery itself that might tell you if the battery is good? I had a laptop with a similar problem and it turned out to be both a bad battery and a bad "power brick". replacing both fixed my issues. Also, try holding the power cable at the point where it connects to the laptop and push to the left or right. A friend's laptop would only start if you held the power cable to the left. Otherwise, it sounds like a mother board issue. Sorry.

Blades wont stop till battery goes flat,then rotate again when you try charge it up

First, chopper must be "off" when charging.
If helicopter is powered off and blades move when it's hooked to the charger, then you have an incorrect charger. It's tricky as they all look the same. At one point I had 3 different "syma s107" helis that all used different chargers. Around 7 different Chinese and Taiwanese factories/companies produce the "syma" branded birds, and often with differing but very similar parts. There are at least 3 circuit board designs, different wiring patterns, and a couple batteries.... I've heard of people receiving a charger in the box with their 107 that didn't charge it. NEVER run battery dead. You will ruin it. What charging method are you using? Does it fly normally when charged? Do the blades ever move when it is powered off and not hooked to charger?

Let me know,
thanks PvT

My 2004 escalade keeps giving me a stability control messege. Then also the traction control messege. What can be wrong?

Either the systems are inadvertly switched off or the system(s) is faulty. Sometimes a low battery charge may switch these off to preserve power and produce similar messages.

Says plugged in not charging

Take out the battery and make sure you can turn on the laptop with just the AC Adaptor hooked up.

If you can then you know the AC Adaptor is good. Try another known good working battery in the laptop, if the battery charges then you know that the old battery is bad.

If the laptop doesn't charge with a know working battery or a new one then you know that the motherboard is bad.

Laptop will not charge, tried other chargers

I has a similar problem with my old laptop. Consider trying a new battery. At some point, the batteries just stop taking a charge. You can get an appropriate battery for your computer on the internet at a reasonable price - check Ebay for the going price for auctions or buy it now.

Battery will not charge

Hi cdravi

Laptops have a power supply control section attached to, or part of the main board. This allows the laptop to switch charging on and off, and control power supply function to different areas of the machine. Sounds like you have a fault in this part of the computer. Off to Dell Service for that one I am afraid.
