My Lenovo Laptop V570 Got Revived After A Lightning Strike
There were thunderstorms in our place a few weeks back and one of the lightnings struck my house and I had a lot of damages. All the CCTV cameras, its console, Wireless Router, one Fan, Set top box and my laptop got affected simultaneously, though some of these damages were realized only later. My laptop did not get on, on the next day. So, I consulted one of my techie friends who were an expert in computer and laptop servicing.
As his place was far away, I could not take it there. So, he told me to go through videos available in the website and dismantle the laptop and locate the LAN port control IC. After scanning a few, I got the following link, which helped me dismantle my laptop (first time in my life!): https://www.youtube.com/watch?v=RCtsY6RykSo
I followed it step by step, by pausing the video until I finished each part. Removed the battery, removed the back screws and cover, disconnected the hard disk, CD Unit, then removed key board etc. as mentioned therein. Then pulled out the mother board, after detaching the display cable and backlight connection.
Finally, I could trace and locate the LAN control IC, with of course great help and guidance from my friend.
His advice was to remove the IC and try starting the laptop. Here the twist started. I tried my best to remove this IC using various methods. As you all know, I have reported removing several such SMD ICs in my earlier articles. I was able to do that without any problems. Even at very high temperature and blowing, it never budged.
I even applied the special desoldering paste, PPD PD-150 and tried. Then I was worried that I was going to cause further damages to the board, which are of multilayer type. Look at the target site:
By this time, I had some urgent personal work. My wife was scheduled to undergo a spine surgery and got engrossed in that. As I had to take her to a place around 150 Kms away, I dropped the laptop en route to my techie friend and requested him to finish the job. He managed to remove the IC after a lot of struggle. As the laptop had a few other problems as well, which were related to hard-disk, software etc. he attended to all that. He replaced the hard disk with a high speed one, as shutting down was not taking place properly. Loaded Windows 10 afresh and related programs as per my requirement. I picked it up on my second trip to the hospital for admission of my wife. The laptop was restored sans the LAN port, as the replacement IC was not available. Even one USB on that side could not be used. Anyhow, the laptop could work through WIFI. This article writing is being done on the same Laptop and I am happy to report that work was accomplished satisfactorily.
This photo was taken when I was checking the laptop, while my wife was undergoing surgery. Group Sherlock Holmes can see the hospital bed on the left side! (LOL) Thus the laptop survived after a life threatening strike by lightning.
The original internal hard disk was housed in a 2.5” USB 2.0 to Sata HDD Enclosure and connected externally. All my data was stored in it. The 256GB HDD inside the laptop was partitioned only to store essential data.
The story did not end there. I was using an external hard disk for backup. That was connected to the USB port next to the LAN port. When I tried to reconnect it to a different port, it showed, ‘over loading!’ Then I almost decided that in the list of damages, this also should be added. But I opened the hard disk and found the following:
Looking at the charred PCB of the interface board, if you have guessed the HDD had gone, you are wrong. I bought another USB port interface board and connected it and found the HDD was unaffected! Well, there is always happiness hidden under the debris, if only we do not easily give up in haste, and continue our pursuit until the dead end! Now that backup HDD is also connected to my laptop through USB Hub! HA! HA!
