Question about Computers & Internet

1 Answer

Compaq c300 It works fine if you put a fresh battery in it but it will not run or turn on using the ac adapter. It is a universal adapter not the origional equipment. The lites flash but nothing else will happen. The last time it shut down it said it was going to hibernate. I cannot wake it up. I have ordered the origional adapter to see if that helps. I understand it was not used for a long period of time. Now will not run on ac power or charge the battery. The battery is 10.8v and the charger is like 18.5, Is that correct?

Compaq 2510p battery not charging


Hi,


Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.


1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.


Hope this will help...Thank you for using Fixya...

Compaq N610c does not power on on AC adapter or on Battery :(


Hello,

it might be that the AC adapter is no more working. To confim this, remove the laptop battery and test the AC adapter with the laptop.

You can also borrow a friend's AC adapter and test it with your laptop.

I wish you good luck.

Hi forum, I have been using Compaq N610c notebook and was working fine but was not power ON . on AC adapter but it was working on Battery. From last day, the battery become zero showing battery indicator...


It's possible that the AC adapter "died", and then your computer ran on battery-power until the battery went to 0%.

Or, the socket on the laptop where the AC adapter connects could have broken, or become disconnected from the motherboard, such that the power from the AC adapter was not being accepted, meaning that your computer was running on battery-power.

Take the AC adapter and the computer to a qualified technician, who can test that the AC adapter is working fine, and can disassemble the laptop, to inspect that socket where it connects.

Compaq Presario laptop C300 - issues (orange light)


Sometimes when a PC gets stuck in hibernation mode, the only way to reset it is to remove the CMOS battery for 10 minutes and replacing it. It resembles a large watch battery and is usually located near the center of the motherboard.

Compaq Presario c300 power light blinks..


It sounds to me like there's a short in the AC adapters causing it to have enough power to charge the unit when it's not pulling power, but once it starts pulling power, it basically becomes overwhelmed and can't do both power and charge. There's also the chance that the DC jack [which the AC adapter plugs into] is bad. However I'd suggest checking the adapter first because it's simple to obtain a new one and if it doesn't work, you can most likely just return it and say it doesn't work as opposed to a dc jack being repaired which would have to be done by a professional with the skills to handle it [of course unless it's under warrenty, less than a year old, but judging by the model I'd say it's probably not]
