Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.
If I remove the...

Acer Aspire 4520 won't turn on after reboot

Hello, I have in my hands an HP EliteBook 1040 G4 (DA0Y0UMBAD0 REV: D) that makes no attempt to turn on, display an image or anything.
I took out the BIOS and flashed one that I found in a forum for this model, and on the first boot it did give a power LED, it showed an image, but I got two HP screens, the first one said:
"Final step of BIOS update is in progress.", after that it turned off and turned on again this time showing the following warning "The BIOS has recovered its identity data from the Embedded Controller due to data mismatch."

Re: Epson PowerLite Presenter L 3 Red LED's Flashing
Of course, no problem. What type of photos would be necessary?
From the projector itself, from the projector board, or from the three lights flashing red?Leave a comment:

Epson PowerLite Presenter L 3 Red LED's Flashing
Hi, I have an old Epson PowerLite Presenter L.
I have the following problem, when I turn it on it starts up normally, the image works correctly, after a while (it can be a couple of minutes, up to hours) it turns off and the 3 LED lights flash red (Temperature, Lamp and Power).
The 5 fans included in this equipment work correctly, I maintained them and verified their correct operation.
I also read somewhere else that it could be caused by cold solder on the connectors, so I put new solder on them and the problem persists.
I can't find... -

Re: DAG94AMB8D0 DIS to UMA
Hello, yes I have the schematic, thanks
What I didn't find was the boardview anywhere, I assume it doesn't exist for that board
That's why I was asking if anyone knew a method to identify the resistors
Or if someone has done this procedure on that plate and can guide me...Leave a comment:

DAG94AMB8D0 DIS to UMA
Hello, I have an HP 15-cd005la, DAG94AMB8D0 Rev D, Model G94A that has a dedicated graphics card that is already giving problems.
I want to convert it from DIS to UMA, I have not found more information or videos about it according to this model.
I only found information in a Russian forum that says that you have to change the resistance of the BOARD ID0 from "1" to "0"
According to the schematic, the BOARD ID0 actually selects whether it is Discrete or UMA, and corresponds to the R68 and R69.
The problem is that I don't have any schematics,... -

It also doesn't turn on the fan, nor the keyboard LED. But it does charge the battery.

Thinkpad E480 BIOS Dump
I have a Thinkpad E480. Type 20KN-003ULM
The problem it presents is that it turns on the power LED light but it never gives video. Last time it worked I left it on and unplugged. It probably discharged and never turned on again. What I found out is that a Firmware update came out that day, I would believe it was attempted to update and ended up with a corrupted BIOS update.
I have tried with other DUMP bios from other posts and they have not worked for me. Here I leave a backup of my non-functional BIOS, I hope someone can help me with my problem.
From now,... -

HP ProBook x360 11 G5 EE - BIOS Need
Hello, I have a HP ProBook x360 11 G5 EE with Motherboard 6050A3112601-MB-A01
If anyone has a functional BIOS for this computer, I would appreciate sharing it.
The problem that the client reports is that after an update that did not allow it to be applied correctly, the equipment does not turn on, the only behavior it presents is that the LED lights blink. It does not give an image or any other sign of life.
In my opinion, it is likely that it was a BIOS update that was not applied correctly, if you...Leave a comment:

Samsung NP270E4E ME Region
Hello, I have a Samsung NP270E4E-K06VE with Motherboard BA41-02206A PIOTEK
The problem it presents is that exactly 30 minutes after turning on the equipment it turns off. I understand that it is a problem of the ME Region, I made a backup of the BIOS, and I flashed one that I found here but the problem persists, maybe someone can help me give me suggestions on what else could be the problem.
I leave the original Backup of the equipment, of course, thank you very much for your help...
