this card is the same as that of the other discussion E5440 VAW30 LA-9832P, connecting power turns on the power led and fan at max for 3 sec then all off, as if you didn't see the ram, then if you turn it on again with the power button it doesn't turn on, I tried to disconnect the power supply and jumper pins 5 and 6 of U1 and U2 while I re-connected the power supply, and it turned on normally, then after turning it off when it was turned back on it didn't turn back on like at the beginning

Re: dell e5440 turns on 3 seconds with fan at max
I solved the problem, making a check of the present voltages, measuring the + 1.35V-MEN-P this was not present, measuring on PQ100 the pins 5-6-7-8 there was no voltage, on PL101 the + PWR- SRC was present on point 1 but not on point 2 of the coil, measured in ohms it was ok but it did not make contact with the pad, the welds on the coil were re-made 1.35v_B + is adorned on pins 5-6-7-8 of PQ100 and so even the + 1.35V-MEN-P is back and the notebook has started working again.

by Kambi13Hi all need some help, I've got a Dell insprion 15 3542 that turns on works for about 30 seconds or sometimes a minute or two and then turns off and wont turn on again until I remove and replug the power connector

by zklgfsHi,
I have an Anker SoundCore 2 (A3105) that I saved from the trash (well, I guess there's a reason why it was supposed to go into the trash...). The problem is that it always turns off after a few seconds (sometimes it stays on a bit longer, between 30 and 60 seconds, but it still turns off). The power light turns on and the bluetooth light starts blinking, but both abruptly turn off again. The "turn off sound" is still played after the lights turn off. Sometimes, it also loops the on-off cycle several times without me pressing any buttons. If I connect an AUX cable, music...-

by twonk9098Hi all,
I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.
I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.
I have tried a few new bios but exactly... -
Do you have any idea what it could be? Thanks.
