hi, with your bios the notebook LED turns on and after 1 second it turns off, while with the other bios it turned on and off 3 times remaining on (always with a black screen).
Could you also explain to me why by reprogramming my backup bios and therefore what used to work now it no longer works?
The problem that pushed me to reprogram the bios was because I couldn't update it and it also had a slow post.
Thank you...Leave a comment:

yes i haven,t video, black screen only
maybe your bios was more updated than mine and maybe something was written in other chips like EC and now putting back my backup, there is firmware incompatibility...Leave a comment:

Hi everyone,
I wanted to ask you if you could explain to me why this dell 5490 fails to update the bios.
When I start the update from Windows with the tool downloaded from the official website, it seems to be installing it and then it asks me to restart the PC but when it restarts the classic bios flash doesn't start but Windows restarts as if nothing had happened.
I also tried to run the update from the USB stick by pressing F12 during the post but the result is always the same.
The service tag is: H27K5Q2 and I also attach the bios file.
Thank you...Leave a comment:

Same problem with DELL EDC41 LA-G891P and DELL EDC50 LA-901P
Hi everyone, I have the same problem with two Dell notebooks. One has the EDC41 LA-G891P motherboard and the other has the EDC50 LA-901P motherboard. Both do not turn on and the processor also heats up a little.
In the coils there are 3.3v - 5.1v - 13v - 19v - 1.8 - 1.05V and 1.0V prime core
On both notebooks, if I press the power button the LED turns red and if I release the button the LED turns off.
What could I still check before saying the processor is dead?
Thank you -
Someone can suggest me to try to replace ILS95859 or will it be useless?Leave a comment:

No +VCORE in acer TravelMate TMP2510
Hi everyone
I have a problem with this laptop that won't turn on.
The +VCORE is not present and doing some measurements on the ISL95859 I notice this:
VIN present 19.5V
VCC present 5V
VR_ENABLE present 3.3V
PWM_A present 2.5V
FCCM_A not present
PWM1_B present 2.5V
PWM2_B present 2.5V
FCCM_B not present
PWM_C present 0.32V
FCCM_C present 5V
In these conditions should the ISL95859 works and therefore enable the FCCM_A and FCCM_B pins or do I have to check other lines for it to be enabled?
Maybe the... -
