Compaq laptop Evo N410c Battery charging

I bought this laptop second hand and was told tht the battery needed replacing.   Bought a new battery and fitted it but there seems to be a charging problem combined with  starting problem.  On plugging into the mains the battery warning light often does not come on to indicate that the machine is ready to be powered up   After unplugging and replugging the light comes on after five seconds and the machine is ready to use.   The light indicates that the machine is charging but at no time can I get a full battery.  The best I can get is 12% and that figure fluctuates down to 9%.   At no time will the mnachine fire up just on the battery.   Potential the battery charger working (properly),  do I have a duff battery?   Can you help?

Re: Compaq laptop Evo N410c Battery charging



First remove the battery and run only on the adapter... If it works fine then there is no problem with adapter...... Charge the battery continuously for 4 hours without seeing the percentage of charging and remove the adapter..... If the laptop runs on battery for 45 mins then it might be the problem with drivers..... Go to device manager and reinstall the drivers if it is less than 45 mins.... Reinstall the drivers either ways...... If still the problem persists.... Go to and and select software and driver downloads and give the product number.... select the OS... Select HP battery check.... Download the file (sp32299.exe) and click save.... Save file onto the desktop and close the site..... Run the exe file.... If it passes the battery is fine... If fails replace the battery....


The steps might be longer..... But i can assure that it will work

A battery would fix this but it is the battery on the motherboard that you need. How old is this computer?

Charging problem

Sounds like a defective battery to me ...or perhaps a faulty charging system. Least expensive solution is run on no battery, AC only. Second cheapest is replace the battery. Third option (note I didn't mention "cheap") is to replace the motherboard. Last option is to replace the laptop (might be cheaper than fixing the laptop, if you factor in age, warranty, time, effort and headache involved.

Hope this helps - remember to rate :)

your laptop should function even without a battery. Remove the battery you just bought and see if only with AC adapter, would your laptop turn on?

If not, then try removing the memory and see using a pencil eraser, clean the contacts of the memory and see if you can power your laptop with only ac

Compaq evo N410c sound and video play too fast

I bought a used Compaq evo N410c and had the same problem.  I went to HP's website and downloaded the ADI Soundmax Audio Drivers and both video/sound are working fine.  The drivers installed without any problems, I was not prompted to insert any disks.  nicole79, sounds like you may have downloaded the wrong drivers.

The below was copyed from an earlier post of mine, it applies to you. It's one of two things, the more likely of the two is that that battery is totaly shot, laptop battery's are usually only good for 1.5 years then loose there ability to retain a charge. It sounds like that one's just done. Unfortunatly that those batterys cost more than there worth, 100 bucks or more. The second possibility is the power cord, is that the original power cord for that? Or was on that was bought aftermaket, some aftermarket chargers will only power your laptop and not charge. Also remove the battery and check for corrison. You can build your own battery fot a a laptop if got a few hours time, and are good with a soldering gun. You get the litium ion cells you need for about 40 bucks. Good Luck Follow the below link for a step by step on how to build your own battery
