The power cord light is on, but the computer does not turn on when I push the on/off switch. It does not light up.
Hi, Try a power reset and see if this resolves the problem. Switch off the charger and disconnect it from the laptop. Remove the battery from the laptop. Press and hold the laptop’s power button for 30 seconds to drain any residual power from the laptop. Reconnect and switch on the the charger to the laptop (leave the battery out at this stage). Start the laptop If the laptop starts, allow it to boot all the way to the Windows desktop. When there wait for the HDD activity to settle before shutting down the laptop in the normal manner. Once it has completely shutdown, switch off the charger and disconnect it from the laptop. Reinsert the battery into the laptop. Reconnect and switch on the charger to the laptop. Start the laptop. If the laptop starts, allow it to boot all the way to the Windows desktop. When there, wait for the HDD activity to settle. Check the battery charge status icon on the taskbar. If the battery is charging, allow it to fully charge before switching off the charger and disconnecting it from the laptop, leaving the laptop to run on the battery.
In my case it was the CMOS battery… Replaced it, now it works. The test is simple. Remove battery, disconnect power source, remove back cover (gives access to HDD, RAM, etc) and *carefully * remove the coin like battery (there’s visual tutorials for this on YouTube). Without the battery, turn it on. You should hear the fans and HDD spinning up. Let go of the power button and press again to force shutdown. I had to get a Duracell CR 2032 (Pharmacies and small stores have them) and replace it. That’s it. Hope this helps. Start saving up for the next PC (parts for this have been discontinued for a while now). Cheers!
@Pat Spencer , Usually there is a label on the underside of the laptop that has the model number/serial number information on it. It can also be found on the box that the laptop came in. Here are some examples of where it is and what it can look like
(click on image to enlarge for better viewing) Also as it is only eleven months old, you do not want to go opening the laptop to get to the battery etc, as you may void the manufacturer’s warranty by doing so. Contact the HP customer service centre in your location and ask for help or make a claim for a manufacturer’s warranty repair. That’s what warranties are for.
