Liquid spills on laptop computers
The repaired many laptops I exposed to accidental spills. This is a condition for recovery in most cases. It is very important to respond to the cleaning process as soon as possible (before soakage internal corrosion or not)! Can cause fluid leakage following types of laptop damage:
Short circuit due to the nature of the liquid wet connector (has an obvious problem liquid and dry)
Short circuit due to dried liquid residue
Corrosion occurs (particularly volatile with some acidic soft drinks - Coke)
Electronic components damaged by short circuits above
Immediately when the leak occurs, turn off the laptop, unlike laptops and leave the unit upside down (drainage) for at least 20-30 minutes. Then remove any lead attached, remove the power unit and battery, and allow the unit to air dry overnight.
To remove any residual liquid: Does someone remove the keyboard and perform additional cleaning Assembly. It may help to use cotton buds and distilled water to remove any contamination. Where the side effects of erosion have suspected (with coke), and gently rub any suspicious areas with a damp cotton bud CRC or WD 40. Drying the treated areas so that only light film solution WD-40 anti-corrosion remains. While removed the keyboard, and the use of bright light and a magnifying glass to examine the areas that made the liquid contact.
Laptop randomly turns off
This is often due to:
AC power adapter sensing an overload of power drain
High temperature processor due to the construction of internal dust (clogged fan)
AC power adapter is able to maintain normal energy needs (faulty power adapter)
Battery overheating, due to error of the internal battery, or the imposition of standards
Intermittent short circuit or open connection (check condition of power leads)
Laptop on the elderly, and the most common cause is a poor cooling. Try going somewhere air-conditioned and see if that helps. Inspect the nearby areas of the internal cooling fan, and see if there is accumulation of dust fibers. An easy way to check it out; with the unit running, feel the flow of air from the cooling outlet (s) - air flow is too low? If the answer is yes, and unity in the normal operating temperature, this may indicate partial blockage and internal cooling system.
Troubleshoot laptop LCD video display
Here are some tips and tricks to troubleshoot and repair problems mobile video. Video issues are very common in laptops and with the following tips you should be able to detect and eliminate the fundamental problems mobile video.
Laptop LCD screen has a faint image or very dark
Look closely at the LCD screen laptops, and see if you can see a very faint image. If you can then it is possible to be stuck in a laptop LCD cover closed switch in the closed position. In this mode the backlight stays outside, even with the lid open LCD. This is to maintain power when the laptop is ON with the lid is closed. Check the LCD cover closed switch. It is small plastic pin located close to the return depends LCD. Try to take advantage of the cover switch several times to see if you can run the screen backlight. If this does not help, then I would suggest to replace the inverter board FL.
Laptop LCD screen is a solid white or discolored
Connect external computer screen to your laptop. If your external monitor is fine, then you have a problem with the LCD screen laptop or LCD cable connection. If the image is the external screen LCD is the same as on the laptop, it is likely to be faulty integrated onboard video, this means replacing the motherboard of the laptop.
Assembly typical laptop LCD display
The above diagram shows the box-simplification of the basic components that are involved on the problem of laptop LCD video display.
Video data is sent from the motherboard through the LCD screen for in Mosul 2: 3 - sites connector 1 - 2. Video cable also feeds voltage inverter board FL in Mosul 3.
FL inverter locations PCB 3 -4: This section convert low voltage DC source (connector 3) for high voltage AC (conductor 4), as it is required to activate the backlight bulb. If the inverter FL PCB is faulty, and the LCD screen will appear as a very bleak picture on laptops display.
CCFL (backlight lamp): When the backlight bulb works, you can see the image on the LCD screen. With some laptops, backlight bulb is part of the LCD screen of the Assembly and needs to be replaced with the full Assembly LCD screen. It requires a laptop repair specialist workshop to replace the backlight bulb.
Laptop Close the lid switch: This switch is a small key (mechanical or magnetic) which is located close to the rear of the display hinges. Most laptops hibernate or operate in standby mode when you close the LCD. This is achieved through communication with the laptop BIOS power management software. This in turn is linked to the Windows operating system.
Laptop is slow and constantly appears in Internet popup
It is very likely with the injury laptop spyware. Spyware is software that hides on your computer and attempts to gather information about your activity on the Internet. Sometimes spyware is transferred to your computer when you download 'unknown' free software or when you link to edit the online music programs (Kazaa, Limewire, Bearshare, etc.). The best way to remove spyware and prevent further Spybot is used. Please read my instructions spyware page.
Laptop is frozen, no response on the keyboard or mouse, you can not stop
With most laptops I have seen that this will happen from time to time! An easy way to solve this problem are:
Cut off mobile
Remove the battery from your laptop
Wait for a short time (10 seconds)
Replacement laptop battery unit
Reconnect the power cord Mobile
Turn your laptop on
The laptops usually begin full operation. If you are working on a Microsoft Word or Excel document at the time of the problem, then you may find that the data was in the auto industry lift you. In this case, you will be automatically prompted to view the document last worked on when you open the program Microsoft.
Troubleshoot hibernation and standby and laptops
Power management options in laptops sometimes cause problems. Hibernate modes and media ready to provide power for laptops battery-operated operations.
Hibernation is a procedure that is stored working condition (contents) of your work to disk before the computer goes into hibernation or standby. When he woke up the laptop to be restored to the exact place where it was before. Standby and hibernate use low power consumption mode, with enough power to keep the content of this memory. This means that the laptop can wake up without a full restart and loss of employment.
Laptops do not wake up from standby or hibernation
Here my test suggestions:
Give it time - some older laptops may take up to 30 seconds to wake up - Full
Some laptops have special keys or buttons for "waking up" - read the manual
Press and hold the power button for five seconds or more laptop. Some are configured laptops to suspend or hibernate with the power button is pressed. And press the power button for a second + 5 usually reset and reboot the laptop
As a last resort, remove the laptop battery and power cord, wait 30 seconds, replace the batteries and reconnect the power cord
Conflict with the Department of Energy laptop BIOS and Windows power management is the most common reason for the failure of such Wake. Try different settings in the BIOS to see if this may solve the problem. Look to see if the BIOS is configured laptop computer to hang, and how it compares with the value that is configured in the Windows operating system. In most cases allow for Windows power management control.
