Re: Lenovo G475 schematics
I've Lenovo G475 with very strange fault! it does power on from Battery but not from Ac Adapter but when AC adapter is plugged in, the charging light blinks and shows charging battery but actually not charging the battery still consumes it's energy and constantly decreases the volume. on the power button always voltage when only ac adapter is plugged in is 16V instead of 3.3V and abt 8V when only battery is plugged in and if both are plugged in then it's normal like 3.3 volts! but it does power on with 8v from battery but not with 16v from Ac adapter only. very strange fault please help if any other technician have same problem.Comment

For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

Request: Lenovo ThinkPad T14 Gen 2 (Intel) Schematics/Boardview
Hi everyone,
I’m looking for the schematics or boardview for a Lenovo ThinkPad T14 Gen 2 (Intel) with the following board:
HT4B07HP4B0 / HT5B1 / HP5B1 / HT4B2 NM-D352 Rev: 2.0
I’m currently dealing with some startup issues and would like to test for shorts. Any help would be greatly appreciated.
Thanks!

I have this Lenovo Slim 7 16IAH7 notebook that is not booting properly. All voltages are there: 5v, 3.3v, 1.8v but it's still a no-go.
I spotted this IC chip with markings "6611c" on it. The coil near this chip measures around 200 Ohms which I think is too low. But without the schematics, it's just a guess.
I wonder if someone has the schematics for this board or perhaps, can help me identify this particular ship. Thanks.... -

Hello, this Lenovo Flex 7 14IRU8 notebook runs off the battery. When charger is plugged in, the charging port stays @ 5v/0a
I suspect the OVP chip may be bad. I am looking for the schematics+boardview for this motherboard to figure out the issue.
Thanks.
