HP Mini 110 Troubleshooting

Display is black, no lights are on, and computer does not respond when power button is pressed

Insert A/C power adapter into the HP mini and plug it into a known working power source.

If the A/C power adapter is the known source of the problem, a new power adapter can be bought here.

If none of the other solutions fix the problem, the system board (motherboard) may be faulty. Replace the system board.

Display is black, or goes black while the computer seems to still be running and will not turn back on when prompted

If error messages are displayed, see this guide.

If not, first perform a hard reset by pressing and holding the power button until the computer switches off. Press the power button again to re-boot the computer. If the problem persists, connect external monitor (you may have to switch to dual screen by pressing fn + f2 once or a few times) and see below.

Perform a memory module self test, as described here.

Perform a primary hard drive self test, as described here. If any parts of the self-test fail, contact HP - the hard drive may be covered under warranty if it failed a self-test. If the replacement isn't covered under warranty, replace the hard drive by following the Hard Drive Replacement guide.

Disconnect and reconnect cables to screen and reboot computer. If this doesn’t fix the problem, replace the screen, follow the Replacing the Screen guide.

Black or gray spots show on screen or screen is visibly cracked

Replace screen by following the Replacing the Screen guide.

One or more of the keys are not depressing, not returning after being pressed, not responding, or acting as though they are pressed when they are not (long strings of one or multiple repeated letters are appearing on the screen)

If rebooting the computer doesn't fix the problem, see below for common causes and solutions. If you absolutely need the use of a keyboard in order to save your data before turning the computer off, obtain an external USB keyboard and plug it into the laptop.

Remove the keyboard and carefully clean any contaminants and dust from under the keys using a soft brush or a can of compressed CO₂ or compressed air (there are brands sold specifically for cleaning computer parts). If this doesn't solve the problem, replace the keyboard. To replace the keyboard, or remove it for easier cleaning, see the Keyboard Replacement guide.

Replace missing keys or replace the whole keyboard.

If the keyboard is not responding, first try cleaning the keyboard (see above "foreign material under keys." If that does not solve the problem, follow the Keyboard Replacement guide.

Computer is excessively hot to the touch or there are warning messages about overheating.

Carefully blow or use a compressed air can for cleaning electronics to clean the dust from the fan and the area around heat sink (this is the large copper plate that covers part of the system board, see Step 10 of the Fan Replacement guide for a visual). To get access to the fan, follow the Keyboard Replacement guide. If you are unable to sufficiently clean the fan, follow the Fan Replacement guide to remove the fan, and then clean the fan itself and the area surrounding where the fan was mounted in the computer.

Make sure feet on the bottom of the netbook are properly in place and make sure the fan inlet is not blocked (by sitting on padded cloth surfaces, or your legs, for an extended period of time while running). Move the laptop to a hard, flat surface. If necessary, replace the feet (see Step 9 of the Fan Replacement guide).

If there are warning messages for overheating and the fan is not turning on, then it is likely the fan is faulty or broken. Follow the Fan Replacement guide to replace the fan.

Touchpad is not sensing your touch, or cursor is moving erratically or unpredictably

If rebooting the computer doesn't fix the problem, see below for common causes and solutions.

Download and install touchpad the drivers from HP here.

In order to ensure the connectors are secure, the touchpad must be disassembled. Once this is complete the connection can be checked and thoroughly cleaned. Follow the Replacing the Touchpad guide to view how to take apart the touchpad.

Take a damp cloth or lens cleaning cloth, and wipe down the touchpad.

If the touchpad sensitivity is too low it may not sense any activity. In order to fix this, follow HP's guide.

Extract any debris caught in the crevice between the touchpad and keyboard bezel, or under the keys themselves. To make this process easier, remove the touchpad by following the Replacing the Touchpad guide.
