Fixing Common Laptop Problems
Liquid Spills on Laptop
I have repaired many Laptops uncovered to unintended liquid spills. This is a recoverable situation in most cases. It is most necessary to respond to the cleansing up technique as quickly as viable (before corrosion or inner soakage occur)! Liquid intrusion can motive the following sorts of laptop computer damage:
Short circuit due to conductive nature of moist liquid (problem may additionally clear as liquid dries)
Short circuit due to dried liquid residue
Corrosion happens (particularly unstable with some acidic tender drinks – Coke)
Electronic elements damaged via above quick circuits
Possible Solution: Immediately when a spill occurs, turn off the laptop, invert the laptop and leave the unit upside down (drainage) for at least 20-30 minutes. Then, cast off any connected leads, eliminate the energy unit and battery, and permit the unit to air-dry overnight.
To put off any liquid residual: Have any individual take away the keyboard assembly and function additional cleaning. It can also help to use cotton buds and distilled water to do away with any contamination. Where corrosive aspect consequences may additionally be suspected (with coke), gently rub any suspect areas with a cotton bud dampened with CRC or WD-40. Dry the handled areas so that solely a light film of the WD-40 anti-corrosive answer remains. While the keyboard is removed, use a vivid light and magnifying lens to inspect areas where the liquid made contact.
Laptop randomly turns off
This is frequently due to:
AC electricity adaptor sensing an overload of energy drain
Overheating processor due to a construct of inner dirt (clogged fan)
AC electricity adaptor now not in a position to sustain regular power wishes (faulty energy adaptor)
Battery overheating, due to inside battery fault, or charging levels
Intermittent short circuit or open connection (check condition of electricity leads)
On older Laptops, the most common cause is poor cooling. Try going somewhere air-conditioned and see if that helps. Inspect the areas near the internal cooling fan; see if there is a build up of dirt fibres. Easy way to check this; with the unit running, experience the waft of air from the cooling outlet(s) – is the airflow very low? If yes, and the unit is at normal operation temperature, this can also indicate the interior cooling device is partly clogged.
Troubleshoot Laptop LCD Video Display problems
Here are some tips and tricks for troubleshooting and fixing laptop video problems. Video problems are very common inside transportable computer systems and with the following tips you should be capable to detect and do away with fundamental laptop video problems.
Laptop LCD screen has a faint image or is very dark
Look closely at the laptops LCD screen, and see if you can see a very faint image. If you can then it is possible that the Laptop’s LCD lid close change is stuck in the closed position. In this mode the backlight stays off, even with the LCD lid open. This is to conserve energy when the laptop is ON with the LID closed. Check the LCD lid shut switch. It is a small plastic pin located close to the returned LCD hinges. Try tapping the lid change a few instances to see if you can turn on the display backlight. If that does no longer help, then I would recommend to exchange the FL inverter board.
Laptop LCD display is solid white shade or garbled
Connect an external pc reveal to the laptop. If the external display show is fine, then you have a problem with the Laptop LCD display screen or the LCD cable connection. If the external reveal image is the equal as on the Laptop LCD, then it is in all likelihood to be a misguided integrated onboard video, this means replacing the motherboard of the Laptop.
A normal Laptop LCD display assembly
This is a simplified clarification of the fundamental aspects that are worried on a Laptop LCD video show problem:
LCD Connector: Video information is sent from the motherboard thru to the LCD screen. A video cable additionally feeds voltage to the FL inverter board on the LCD panel
FL inverter PCB: This part converts the low voltage DC source to excessive voltage AC, as required to energise the backlight bulb. If the FL inverter PCB is faulty, the LCD screen will exhibit a very dim picture on the Laptop show screen
CCFL (backlight bulb): When the backlight bulb is working, you can see the photo on the LCD screen. With some Laptops, the backlight bulb is a phase of the LCD display screen meeting and needs to be replaced with a complete LCD screen assembly. It requires a specialized Laptop repair workshop to exchange the backlight bulb
Laptop Lid shut switch: This change is a small change (mechanical or magnetic) that is placed shut to the rear display hinges. Most laptops will both hibernate or operate in standby mode when the LCD is closed. This is carried out by interfacing with the Laptop’s BIOS power administration software. In flip this is linked to the Windows running system
Laptop is slow and continually suggests Internet popup’s
The Laptop is very possibly infected with spyware. Spyware is software that hides on your pc and tries to gather records about your exercise on the internet. Spyware is once in a while transferred to your pc when you download ‘unknown’ free software or when you hyperlink to free track Internet packages (KaZaA, Limewire, BearShare, etc). The high-quality technique to dispose of and similarly stop adware is to use Spybot. Please examine my Spyware Software Help Page.
Laptop is frozen, no response to keyboard or mouse, cannot Shutdown
With most Laptops I have seen that this will appear from time to time! The convenient method to resolve this trouble is:
Disconnect the laptop computer strength cord
Remove the battery from the laptop
Wait a short whilst (10 seconds)
Replace the Laptop battery into the unit
Reconnect the Laptop Power cord
Turn the Laptop on
The Laptop will begin commonly and be wholly operational. If you have been working on a Microsoft Word or Excel report at the time of the problem, then you can also find that the facts has been auto-recovered for you. In this case, you will be mechanically caused to view the remaining record you worked on when you open the Microsoft program.
Troubleshoot Laptop Hibernate and Standby problems
Power management alternatives on laptops on occasion to motive problems. Hibernate and Standby modes are power saving modes of operations to battery powered laptops.
Hibernation is a manner via which the working kingdom (contents) of your work is stored to disk earlier than the laptop goes into hibernation or standby. When the Laptop is woken up, you are restored to the specific place you had been before. Standby and Hibernation use a low strength consumption mode, with adequate power to hold the content of such memory. This capability that Laptop pc can wake up without a full restart and loss of work.
Laptop does not wake up from Standby or Hibernation
Here are my tested suggestions:
Give it time – some older Laptops may take up to 30 seconds to wake up – fully
Some Laptops have one of a kind keys or buttons for ‘Wake Up’ – examine the manual
Press and maintain the Laptops energy button for 5 seconds or more. Some Laptops are configured to Suspend or Hibernate with a press of the power button. Holding the strength button for 5+ seconds will generally reset and reboot the Laptop
As a final resort, take away the laptop battery and the strength cord, wait 30 seconds, exchange the batteries and reconnect the power cord
Now that the Laptop is operational, you lookup the underlying problem. Typically, such issues arise from a disagreement either between the strength management features of the Laptops BIOS and Windows.
A combat with the Laptops BIOS power administration and Windows power administration is the most frequent reason of such wake-up failure. Try exclusive settings in the BIOS to see if that would possibly remedy the problem. Look to see if the Laptops BIOS is configured to droop the computer, and how it compares with the cost configured in Windows. In most cases let Windows manipulate the strength management.
