Hi, When the laptop has been turned on do you get the Windows startup audio, indicating that it has booted into Windows? If not, try getting into BIOS on startup by pressing the Novo button on startup and check if you can get into BIOS with images on the display. If so, try shining a torch at an angle close to the screen and check if you can detect any images at all. If so, then there is a backlight problem with the screen. It may be that the spill blew the backlight fuse on the motherboard. Usually the fuse is mounted close to the video cable connector on the motherboard, so you may be able to check it with an Ohmmeter to see if it is OK or not. If the fuse is OK and that there is voltage at the fuse when the laptop is turned on, then it may be a problem with the display itself. If there is no backlight voltage at the fuse then the problem is on the motherboard. Check for any damaged components due to the spill. If not, then try connecting an external monitor the the laptop and check if it has a display...

Hi @frnw , Have you checked if the power outlet is OK? It may be a faulty switch in the outlet. Try connecting to another outlet. Also if the TV is connected via a powerboard (powerstrip?) connect it directly to the wall outlet if you have proved that the wall outlet is OK The power board sends a voltage signal to the mainboard when there is power connected to the power board and it is the mainboard that turns on the Standby power light if the signal is the correct value. If the power outlet is OK you would need to check the standby voltage on the power board first to determine where the problem is.

Hi @tinamathew When the laptop is on, can you feel the hot air coming out of the vent or hear if the fan is operating? If not then there may be a problem with the laptop’s fan. If the fan is operating then most probably it needs to be cleaned of any dust build up and the thermal paste on the CPU needs to be removed and replaced as it will have dried out, therefore the heat transfer from the CPU will be reduced and it will operate hotter. Here’s a link to the ifixit Acer Aspire E1-571 - Heat Sink Cleaning, Thermal Paste Replacing guide that will help If the fan is not operating it may have to be replaced. Replacement fans are available online. Just search for Acer E1-571G Cooling fan to get results for suppliers that suit you best. See above for how to access the fan so that it can be replaced. If doing this yourself seems too daunting, contact a reputable, professional laptop repair service and ask for a quote

Hi, The camera module may have been damaged by the fall or perhaps it is only a loose cable connection from the module to the board.

Hi, Does it do this when listening using the TV speakers? Just trying to narrow it down to whether it happens to all audio or only to audio using external speakers. Just verifying that the TV audio settings Digital Audio out= pcm and eARC=On and that you are using HDMI1 on the TV and HDMI Out ARC on the soundbar? Also check that the TV firmware is up to date. Even though the TV is new it doesn't mean that it has the latest firmware. It may have been stored in a warehouse somewhere before being sold and in the interim an update may have been released for the model to upgrade features or to overcome a problem that has come to the manufacturer's notice. You might want to check the firmware in the soundbar also as there is a recent update for it as well. It is always worthwhile to check if the firmware is up to date. If it is then it can be eliminated as a possible cause of the problem.

Hi, The impurities in the coffee causes corrosion and provides circuit paths for the electricity which were not in the laptop’s operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away First do not try to charge or to turn on your laptop and then remove the battery as soon as possible from the laptop to minimize any further damage. Then you need to dis-assemble the rest of the laptop and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and liquids. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better Here is a link that describes the process.

The 3rd wire from a battery is usually connected to a thermistor attached to the battery which signals the temperature (resistance value changes with temp) to the battery management circuit in the motherboard.

Charging will be halted to if it got too hot before being fully charged, which may create problems e.g. a fire

If leaving the 3rd wire disconnected, the battery should not be left unsupervised whilst it is charging

Hi @captainsnowball ,

FYI

voilà French exclamation - meaning “There it is!” or “There you are!”

The “red thing” in Step 3 is most probably an IR filter, to filter out visible light to improve IR operation
