Hi there, thank you so much for your videos, you've saved me on multiple occasions! I need your advice for a the same Lenovo G50-30 as in the video but with a i3 chip. The problem is, I have both LEDs working, but it doesn't start up and shows nothing on external screen. Also please explain how exactly do you short the CMOS battery since it's not visible on the video. Thank you in advance!

Good Job , Gracias 🙏🏾

UPDATE! Problem solved! I finally found the BIOS chip and reflash that with SOFI Flypro device by downloading the BIOS binary from a russian site. I found the BIOS chip by meter the voltages on each chips. My laptop: Lenovo G50-45. So if every voltages are OK, you have to find the BIOS EEPROM and reflash it with an external device. Thanks, master for your vids!

Hello what used laptop would you recommend for about 200$ , was thinking of thinkpad t420 i5 2520m , is it any good ? Thank you

Thats weird watched that (and other your videos too) checked all power 19v present, battery power too, shorted bios battery for long time, battery voltage seems to be fine 3v, 5.5v present, all fine, heated startup chip with hair dryier for now very close to the chip. Chip was red hot, but nothing wont turn on? Do you have any thoughts? My model is same but with i5 in it. Dont want to throw it away its only 1 year old. Was working fine before. Changed charging port as positive wire came out and dont really know how did u fixed that. Can not find anything what was its problem. What county are u based btw? I might just come and drop you laptop if its close enough. Hope u can help. If no just let me know u cant help me. Anyways very good videos! Loads to learn from you already!

No, it's most likely the graphics chip.. You will need to reflow it using the heat gun.. It should work. Note that it's not permanent solution and you will most likely have to do that again in few weeks/months/a year.. He has a video on that exact fault and fix. You should watch it.

Hi please I want to ask. I have a Lenovo B50-80 and I can't turn it on. Once connected, the board heats up in the processor area. When I measure the USB power I measure 0.2-1V. The main battery has 2V. Small battery 3.1V. The power transformer is fine. After pressing the power button, the netobook does not start, the diodes do not light up. Thank for help.

Hello i would like to say that all of your videos are great and enjoy watching them. I have a problem i wish you could maybe give some tip in repairing my system. It is the same shitty laptop as in this video. I have tried with two repair shops already and both are saying that the cpu is dead which i dont believe is true. I want to give it a go myself i know basic visible fault repairs. The equipment i have is a digital multimeter and a soldering iron. The things im missing is power station and hot air station. I have tested for voltage with multimeter on the board and it stops at one of the switching chip near the power connecter and does go any further rest of the board. I want to ask you that is there anyway we can test the cpu is dead or not for sure.

Hello Sir. I have a lenovo b50-80 which runs normally and shuts down completely after 2-3mins. What could be the problem? No overheating at all

salut!, am un lenovo g50 si daca folosesc o baterie de la alt g50 laptop ul functioneaza insa nu incarca bateria si nici nu merge fara baterie deci nu primeste curent, am masurat in interior la cablul de la mufa unde intra in placa de baza si voltajul este ok, sa fie un mosfet??

my laptop is also lenovo g50-30. it was working.and I plugged it into the charger while the charge was running low. shows that it is charging but the percentage did not increase and turned off. I replaced the battery, the laptop burned out and worked, and turned off again without power. then the indicator also did not light up. this laptop does not burn only through the charger without a battery. in fact, can this laptop burn without a battery (with charger)?. if you know the condition of my laptop please help me. thank you so much for your help. I look forward to your reply.

Beautiful video! For the power light to come on for me on the motherboard, I used the positive lead from my Volt meter (with my negative lead on ground) and probed the outer connections of the ITE chip.

hello i just fixed a i7 g50 with your help in this video, i jumped battery no luck,,,, I heated up the chip and the laptop powered on and Continue to work for several hours.. but after a few power cycles it would do the same. after it stopped working i jumped the battery but no luck,, 5 minutes later I tried again Powered up fine. After playing with it I realize now that resetting the battery will get it to boot.. If I close the lid and I let it go into power save mode it will never wake up.. Requires me to shut down with the power button After that it will not turn on and I would have to start the process over to turned on again. there is a few seconds after resetting battery before will power on.. I was wondering if the laptop in Video continues to work fine after it was Returned to customer. and if replacing this chip could be a permanent fix,
