Why won't my laptop charge?

Anyway, I spilled fluids (soy milk) into my ThinkPad E580. I remember I could still power it up and use it as usual, but when I tried to charge it it won't charge. So consequently when the battery drained out the laptop was as good as dead.

I tried using different power adaptors to charge the laptop, but to no avail. I have tried the usual methods of removing the battery and charger/long press the power button for 30 seconds/and try charging again methods, but no luck there either.

I have since contacted the official Lenovo repair centre, and they upon inspection reported fluid damage (obviously). The repairs they have quoted me were hugely exorbitant, listing repairs from the System Board to the IO Board akin to the reconstruction of the whole laptop, which amounts to more than $2000 AUD. I only bought the laptop brand new for $1400.

I highly believe Lenovo is just trying to rip me off; the machine does not need a complete reconstruction with new parts. It was working fine after the spill, so it indicates the motherboard, HDD etc, are all still working perfectly well, with the only problem being the loss of battery charging. I believe I just need to somehow get the battery to charge. I don't think a new battery is the solution as the battery was working well before (sans charging), but does anyone know what parts I could think of replacing to get it to charge properly? Maybe the replacement of the charging port? Anything else?

I have linked to photos of the inside components of the laptop to show the extent and nature of the damage.

Any help would be much appreciated. I only bought the machine for a year and now its been on the sidelines for half a year. I really love my Thinkpad.

TLDR: Fluid damage, afterwards laptop was working fine but won't charge. Battery drained out and now machine dead.

Hi @chanelpreston ,

For starters, unfortunately the links to the images that you posted don’t work.

Here’s how to add images in ifixit if you want to try it another way iFixitでの質問に画像を追加する方法

It’s like anything you try to rebuild using spare parts, it always costs a lot more to build than if you bought it new and then you have to factor in the labour cost as well.

Does the laptop still work with the charger connected?

If not it may be too late to save the motherboard or any other boards located in the laptop but you could always try.

Corrosion is an ongoing process and doesn’t stop until it has been appropriately cleaned from the boards. It is even worse if there still is (or was) power available on the boards as well, because the impurities in the liquids create circuit paths for the current which may not have been in the design of the laptop and can damage the components. Even though the laptop is turned off, there is still power available at various points on the boards. The power button is not a power isolating switch.

The longer that the laptop has been left in this condition and not treated appropriately the harder (and more costly) it will be to try to resurrect it.

You could try cleaning the boards as described below and see if that improves anything.

After that you may have to search online for the individual component parts that are the worst affected or don’t work at all, to see if you can get them at a better price and install them yourself.

Here’s a link that may help. Type Thinkpad E580 in the search box and then select the appropriate to your model variant option that appears. In the next page type in the machine number of your model - it should be on the model information label on the bottom of the laptop.

You will get a list of parts that are compatible with your exact model. The reason for doing this is to get the part numbers for the various parts. If you then search online using the part number only you’ll get results for suppliers of the correct part so that you can get the best price.

Cleaning:

Dis-assemble the laptop and clean all the affected parts using Isopropyl Alcohol 90%+ (available from electronics parts stores) to remove all traces of corrosion. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain scents and is not as effective. If you do check the label to verify the amount of IPA

Here is a link that describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.

Hopefully after you have done all this the laptop might possibly work correctly again.

Here is a link to the service manual which may be of some help.

If this process seems too daunting, take your laptop to a reputable, professional laptop repair service experienced in liquid damage repair and ask for a quote for a repair.
