HP G62-340US Troubleshooting

This is the troubleshooting page for the HP G62-340US laptop. Please look below to see troubleshooting solutions

No Power ¶ 

"Nothing happens when you press the power button"

Faulty AC Adapter ¶ 

First, you have to ensure your AC adapter is a genuine HP part and it is supported HP accessory for your computer. If the AC adapter light near the notebook power port won’t turn on after you plug the power cord into the wall outlet, that is the issue with your AC adapter. You probably have some physical damage on your AC adapter, cords or cables. If it is some serious damage that cannot be fixed, you should consider purchasing a replacement adapter.

Faulty Battery ¶ 

If the computer won’t turn on in the condition that your AC adapter works perfectly, it is probably your battery has lost its capacity to hold a charge. In this case, you have to consider purchasing a new battery and replace it by following our replacement guide.

Keyboard/Keys Not Responding ¶ 

"Pressing keys does nothing"

Keyboard Is Not Working ¶ 

If the entire keyboard is not responding, check our replacement guide for the keyboard to fix it.

Keys Are Stuck ¶ 

If a key is physically stuck in the down position, there might be some liquid or substance getting into the keyboard. To fix this, you need to carefully remove the key by following our replacement guide and clean the underside of the key by using a swab. Once you are done the cleaning, replace the key by snapping it back into place.

Keys Are Missing ¶ 

If a key is missing, you need to find an identical key and put it on the keyboard by following our replacement guide.

Computer Repeatedly Crashes ¶ 

"When using the computer, there are frequent error messages during and after booting the device"

Hard Drive or Memory Failure ¶ 

Without messages specifically informing the user of what hardware is failing it can be a challenge to discern whether the memory or hard drive is causing the errors. It is suggested that before replacing anything, you remove both the memory and the hard drive and inspect them for any obvious external damage, then replace them using the guides here.

Optical Drive Not Reading ¶ 

“When inserting disks into the optical drive, there are issues properly loading disks”

Broken Disk ¶ 

The disk itself may be scratched or otherwise made unreadable. To check this, try putting it into another optical drive. If it also fails, it is likely that the disk is broken.

Optical Drive Failure ¶ 

If you confirm the disk is not broken then this most likely means your optical drive is itself is broken. If this is the case, follow our replacement guide to remove the optical drive.

No Sound ¶ 

“You hear nothing from the speakers”

Faulty External Speakers ¶ 

First, you have to make sure your external headphones or speakers are pairable with your laptop and fully inserted in your laptop. If you still hear no sound only when you are using external speakers, then the problem might come from your speakers. You should try using another set of speakers. If the second set of speakers works perfectly, then the first set of speakers is definitely faulty.

Faulty Driver ¶ 

It also could be faulty audio driver causing this problem. In this case, you should restore the original audio driver for the device. To restore the audio drive, first you need to do is searching and opening HP Recover Manager in Windows. Next, click the Reinstall drivers and/or applications option in the window popped on your screen. Then select the audio driver in the list, click install and wait for the installation to be completed. After installation and restarting your computer, your problem is solved.

Faulty Headphone/Audio Jack ¶ 

An alternate issue could be that the computer's jack is faulty or broken in some way, but make sure that you have tested the previous possible fixes first, as otherwise diagnosis can be difficult. If neither of the above is the issue, then the jack is most likely where the problem lies. Follow our guide on how to replace the headphone jack for more information.
