Laptop dust removal techniques

The arrival of summer many has been in service for many years in the laptop care-laden, years of use to make their body has accumulated a lot of dust, thedust seriously affect their laptop cooling system, body heat if not properly discharged may make the laptop running speed slow, serious word even directly to shut down the system. So a clean-up work on it in the summer before the arrival is very necessary. This paper takes HP G4 as an example, the matters needing attention in cleaning work to introduce some laptop, I hope for your help.

　　We used to do today is HP example models of G4, according to its owner says it has been in service for 3 years, never had a cleaning work. Cleaning before the start, the stability of the system testing tools we use AIDA64 to make it full loadoperation for a period of time after the use of thermal imaging instrument to detect the highest temperature of the radiating port, once more than 70 degrees,feels hot feeling, the keyboard surface maximum temperature is reached 39 degrees, the fan has been crazy rotating.

　　The so-called to do his work well, must first sharpen his tools, to prepare a set ofeasy tool can help you to easily open machine, a screwdriver, a lever, a brushadd another blow on it. In addition, heat dissipation grease is prepared on CPUand graphics chips, also must have a.

　　Always must disconnect all power, unplug the battery. Unscrew the bottom shellof all screws, first will be relatively easy to take apart the hard disk, CD driver,memory and wireless cards down.

　　When removing the wireless card must remember two antennas in order, ifinserted opposite the will not be able to use the wireless network installation。

　　At the bottom of the screws are unscrewed the keyboard removed, use a hard object against the fixed keyboard buckle to simultaneously use the crowbar one point one point pry, laptops in general there are seven buckle, the upper part of the keyboard has three, about two each, slowly and gently pry the can. Many laptopkeyboard at the bottom are provided with screw fixation (screw in beside the keyboard identification), so make sure the screw has been removed in thedemolition of the keyboard

The keyboard cable HP G4 connection mode is simple, installation must pay attention to the alignment cable and clamping groove. Buckle type cabledisassembly is very simple, as long as the buckle upwards out of the end head ofthe cable can be blue, the installation time as long as the attention positioninserted tightly and press the buckle can be. All screws are unscrewed so

　　The keyboard cable HP G4 connection mode is simple, installation must pay attention to the alignment cable and clamping groove.

　　Buckle type cable disassembly is very simple, as long as the buckle upwards out of the end head of the cable can be blue, the installation time as long as the attention position inserted tightly and press the buckle can be.

　　All screws are unscrewed using a crowbar or other flat, hard things along the edge of the housing at one point one bottom shell and C separation.Encountered resistance when not used brute force to break, back to check whether there is still no unscrew screw. Confirm no screws after one point onepoint gently pry.

　　The keyboard apart after disconnect the device and the motherboard C shell on the cable can be C shell removed, you can see the C shell above attached a lot of stains, use the brush and clean the toilet paper. A cable touch control boardand the power switch in the C shell, cleaning is completed must remember the security back.

　　Open the C shell and then we will be able to see the most importantm other board, depending on the design, the fan some laptop can now open. HPG4 needs to keep the motherboard to take down, pay attention to all kinds ofcable above the main plate and hide in the corner of the screw, re installation do not install the wrong.

　　Screen cable is compared commonly big, installed a lot of attention is insertedfirmly

The laptop interface position different is not the same, so the position and themethod of removing cable also has many kinds, in general are generally hardplug and the plastic buckle, plastic buckle mode with fixed cable easy disassembly and assembly, and the use of hard plug fixed cable in the demolitionmust be light and slow, especially pay attention to not with hands

　　All cables and screws were removed gently board will be take down from thebottom shell. The demolition of cooling copper pipe and fan work is relatively simple, as long as the fixed screw them down to. The design of this table HP comparison of G4 flower, connection way of fan and the motherboard is unexpectedly the double-sided adhesive, small make up in several attempts togive up their separation idea, if hard and will likely motherboard broke。

　　Pay attention to the connection line of the fan and the mainboard is disconnected, the installation must be remember back. Also note that several fantop screw and edge buckle. This table fan HP G4 because and motherboard with double-sided adhesive together, so it cannot be completely disassembled, dust can only open a gap in a little bit of cleaning the inside of the.

　　Use the brush tool such as a little bit will be attached to the dust on the fan to clean in the radiating port position also has a lot of dust will plug the cooling channel, be here to clean up.

　　Because down directly remove this HP G4 cooling copper pipe and fan can not,so small make up the decision to make the CPU removed and smearing greasework. If the cooling copper pipe you can be directly removed, this work can be directly in the CPU base, heat radiating copper pipe on the residual grease alsomust wipe!

　Smearing grease steps, first of all will be the original attachment on CPU greasewipe, and then in the drop on a small amount of grease on the new CPU, use the tools in CPU wafer evenly coated with a thin layer of good

The bottom shell will accumulate a lot of dust, use a brush to clean up. Cleaning up after the completion of the radiating copper pipe and fan re installed backboard, pay attention to the fan power re inserted back into the motherboard, four screws on the CPU into place. A separate graphics card machine in the same way. All parts are installed back shell

　　Cleaning up after the completion of the radiating copper pipe and fan re installed back board, pay attention to the fan power re inserted back into the motherboard, four screws on the CPU into place. A separate graphics cardmachine in the same way. All parts are installed in the back casing. Screw in allinstalled before electrify switchs on the mobile phone to see is not all parts are installed correctly, to avoid all the screws are screwed back found that certainfunctions cannot use normally need to re open the installation.

　　This HP G4 clear the highest temperature ash after the bottom shell fell nearly 20 degrees, no hot feeling, so cleaning is of great help for the poor heat dissipationof the old book. In fact, disassemble and is not a difficult thing, as long as thepatient, careful pondering can into the machine can easily into the laptopdeashing, if your machine is still in the warranty period can also apply to let the professional brand customer service to help you clear ash, this service is free of charge, you can make your laptop brand the after sale service hotline.
