      The power adapter is under rated or is being perceived as being under rated. On HP, an analog voltage is used to gauge the power adapter's rating. Check the model's adapter rating and be sure it matches or exceeds this value. Check the bios to confirm which power adapter rating is being detected.

          If it's underrated why it's charging it while it's off

              In this case, the adapter is unable to power the logic board AND charge the battery.

                  But at least it should turn it on without the battery being connected

                      Attach the adapter. Measure the voltage to ground of the AD_ID signal.

                          Dell Latitude 5530 BIOS Password Removal Attempted but I Broke the Laptop
                          by TopPop
                          Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.

                          I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip...

                          MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
                          by RdeveLabs
                          To all the members here...

                          Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

                          So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...
