Lenovo Thinkpad Edge E430 - replaceHDD with SSD Question Lenovo thinkpad t530 display not working (Unlike many laptops, the Lenovo ThinkPad Edge E420's power jack - and Ethernet jack - is mounted on a card that is relatively inexpensive to replace compared to the motherboard.) But I would welcome suggestions from people more familiar with the Lenovo ThinkPad Edge E420. The question is: where? My first inclination is to try replacing the power/Ethernet board, since that's much less expensive than replacing the motherboard.

I did try a BIOS update after I had recharged the E420's battery, but that did not fix the problem.ДЄll of this points to a hardware problem.

The behavior - i.e., runs on battery, but not on adapter, including behavior of the charge indicator light - persists whether or not Windows is running, so it's definitely not a problem with Windows. If I leave the battery in and unplug the AC adapter, the charge light goes off (and, of course, Power Manager reports that there's no longer an AC adapter connected). If I remove the battery, the computer loses power and the charge indicator light goes off. One curious symptom I noticed is that the E420's charge indicator light - a tiny LED located next to the power jack - only lights when the AC adapter is connected and a charged battery is installed. I ran Power Manager on the SL410 and compared that readouts on both computers for each adapters, and they were similar.ДЄll of the above would seem to rule out problems with the E420's AC adapter and battery. When I ran Lenovo ThinkVantage Power Manager on the E420, it detected the presence of an AC adapter when one was connected, and even displayed the amount of current it was receiving from the adapter. Meanwhile, I confirmed that the E420 can run on, but not recharge, either battery, no matter whose AC adapter is connected. I also used Lenovo's ThinkVantage Power Manager to check the health of his battery, and it still reads as healthy. The E420's battery charges up just fine in my ThinkPad SL410 using either AC adapter. I have a compatible ThinkPad (SL410), so I used that to test the E420's AC adaper and battery. After awhile, though, it stopped charging altogether. Over the last couple of weeks, it acted as if there were a loose connection somewhere: sometimes it was possible to get it to work and charge the battery by moving the cord or the computer around. I am trying to fix a Lenovo ThinkPad Edge E420 that won't work with its AC adapter, but detects its presence, as strange as this may sound.
