Can I safely use an air compressor to clean the internal components of a computer or might hardware be damaged if the air compressor is too powerful? A few comments from overclock.net: I still use my 100 psi compressor fill it to like 50 or less and I blast away. After 2 years now nothing has been damaged. I've done it on a variety of motherboards, OEM and Enthusiast. I haven't personally used it, but I see some people recommend it around here. I just take my tower out to the garage and blow it out with a big compressor, I'm sure any one would do. “Canned air” (pressure around 30 psi) may create static electricity, contain gases that are harmful to the environment and contain a chemical (to prevent abuse) that leaves a residue so “an inappropriate choice for cleaning anything users will come into contact with such as keyboards”. Yet more details available here: Suck or blow? What's better for dust? Re use of vacuum cleaners: Is it dangerous to vacuum-clean motherboards (and other electronics) where compressed air cans are also considered.

An air compressor is likely not safe. Although a small one might be OK, use caution. Compressed air, in a can form is useful tool. Be careful around moving parts, as to not strip or force them out of their casings (Fans). Use short bursts at least 8 - 10 inches from the components so you do not produce condensation. This should really only be used for removing dust, not fine cleaning.In this post I provide a few liquid spill repair tips. IMPORTANT: If you spilled something on your laptop you should stop using it right away, even if it appears to be running good. Right after the spill you should turn it off, unplug the power adapter and remove the battery. The laptop should be disassembled as soon as possible and all internal parts should be inspected for liquid damage. Liquid spills are very unpredictable. Even a small liquid spill can cause serious damage. IF YOU SPILLED A SMALL AMOUNT OF LIQUID Let’s say you spilled less than a teaspoon of liquid on the keyboard and it stopped working properly, but anything else works fine.

In this case it could be enough to remove just the keyboard to evaluate the damage. Turn off the laptop, unplug the AC adapter and remove the battery. Now remove the keyboard and take a closer look underneath. Search for any liquid presence under the keyboard. – If you see liquid on the motherboard, you’ll have to disassemble the laptop completely for the further inspection. – If the motherboard appears to be completely dry, do not disassemble it any further. air grain cleanerReplace the keyboard with a new one. what air purifier is best for dustHopefully replacing the keyboard will fix it.spray brush cleaner recipe IF YOU SPILLED SUFFICIENT AMOUNT OF LIQUID If you spilled a lot of liquid on the laptop, turn it off right away.

Unplug the power adapter and remove the battery as soon as possible. Most likely it will be necessary to remove the top cover and inspect the motherboard for the damage evaluation. Search for any liquid presence on the back side of the top cover and motherboard. If the motherboard is wet, remove it from the laptop and inspect the other side. HOW TO CLEAN UP LIQUID DAMAGE Wipe it out liquid with a soft cloth. Ideally, use an air compressor to dry the motherboard. Be very careful wiping the motherboard because it has too many small components. If you find any corrosion, you can clean it up with a toothbrush and 91%-99% isopropyl alcohol. Make sure the motherboard (or any other internal component) is completely dry before testing it. IF YOU SPILLED SOME LIQUID ON THE SCREEN If you spilled liquid on the screen, wipe it out clean as soon as possible. The liquid might get inside the screen and damage it. In one of the previous post I explained how to clean the screen with liquid damage.

Believe me, it’s not easy. But if it happens, just replace the whole screen. HOW TO ASSEMBLE THE LAPTOP AFTER CLEANING You’ll have to assemble it back together step by step. First, assemble just main components: motherboard, CPU with the cooling fan and RAM modules. Now turn it on and test basic image on the screen. If it turns on and you can see the image, start adding other parts one by one and test after each step. If the laptop doesn’t start after cleaning, take another look at the motherboard and other components. Maybe you missed a small damaged area. Try cleaning it again. If it still doesn’t turn on, most likely the motherboard (or other component) is damaged. HOW TO RECOVER DATA FROM HARD DRIVE Let’s say the laptop is dead and you cannot do anything to make it work. You still should be able to recover personal data from the hard drive. I assume the hard drive wasn’t damaged by liquid. You can access data using a USB enclosure.

HP Probook 6450b Fan Cleaning & Thermal Paste Replacement HP Probook 6450b Fan Cleaning & Thermal Paste Replacement Arctic Silver Thermal Paste Is your laptop constantly overheating and shutting off? This could be due to a clogged vent fan and/or burnt out thermal paste on your heat sink. Thermal paste is a conductive paste that allows heat to transfer from the electrical components in your laptop to the heat sink, and ultimately out of the computer. Save yourself some money, and learn how to keep your laptop nice and cool with this guide. Shut down your laptop completely. Do not simply power off your computer using the power button. This will put the laptop into sleep mode. Instead, shut down the laptop from the start menu. Unplug the charger cord and all devices connected to the computer. Flip the laptop over and locate the battery compartment release latch. Slide the release latch to the left to release the battery. Electrostatic shocks can damage the internal components of the computer.

Press and hold the power button for a minimum of 10 seconds to allow electric charge to dissipate from the motherboard and internal components. Optional: You may also wear an anti-static bracelet during the repair as a safety precaution. This grounds you to the computer chassis and prevents accidental static discharge from your fingers. Locate and loosen the 3 Phillips PM 2.5 x 11.0 screws on the bottom side of the computer. Flip the laptop right side up and open the screen. Locate the 4 keyboard tabs. Slide the tabs towards you. Lift the keyboard by the upper edge, then flip it over so the ribbon cable is exposed. Do not attempt to remove the keyboard until the ribbon cable has been disconnected. Lift both ends of the plastic tab securing the ribbon cable to the system board with the help of a spudger. If you don't have a spudger, any plastic item with a thin edge, like the plastic opening tool pictured here, will work just as well. Guitar picks are also a good alternative.

Remove the keyboard ribbon cable and set the keyboard aside. Close the laptop and turn it upside down. Remove the 3 PM 2.0 x 3.0 screws securing the switch cover. Flip the laptop right side up, and open the display. Locate the LED board ribbon cable. Lift both ends of the plastic tab securing the ribbon cable to the system board. Slide out the LED board ribbon cable. Remove the switch cover. You may need to use the spudger or opening tool to pry open the switch cover. It is easiest to start from the top edge, closest to the screen. Locate and loosen the 2 slotted Torx T8M 2.5 x 7.0 screws securing the fan to the motherboard. Disconnect the fan cable from the board. Lift out vent fan. Clean the dust from the fan with a small brush and/or compressed air. When using compressed air, avoid tilting the bottle greater than 40 degrees from vertical. Doing so will cause the part and your hand to rapidly cool. Locate and loosen the 4 Phillips PM 2.5 x 9.0 screws securing the heat sink.
