Acer 5560 Bios Corrupt After Windows 10 Upgrade
Last week my brother upgraded his Acer 5560 laptop drivers on request of Windows 10. After that the laptop no longer worked although Windows was the one that had assured him that the proposed driver upgrade was for his laptop! The laptop was fine before but the laptop never switched completely off. Because Fan and the blue power on Led stayed active. Only a long 5 second press on the Power push button switched the computer completely off. And on Youtube videos they showed that a driver upgrade should fix this problem.
But instead now his laptop never completed its boot sequence anymore and kept resetting just before the Setup and Boot select options showed. And both his Windows 10 SSD and HDD (copy) drives no longer booted.
And although a lot of good videos explained how to fix a bad Bios chip by creating a crisis boot memory stick like the following 2 links, the laptop now also simply refused to boot from this usb stick that had the correct Bios driver bin file.
So there was no other option than to remove the 25L1606E (above photo) Bios chip from the mainboard and flash it manually by using the trusted TL866 programmer. First making sure that the online given Bios (JE50) 2048 byte file didn’t verify the same as the data in the removed Bios chip.
And also saving that original read Bios file in case the online found file didn’t work. His laptop was also made faster with a installed Samsung SSD hdd drive. And with the Samsung software the laptop was also easily upgraded to AHCI which made it also about 30% faster. But this now probably caused that no USB stick booted in order to reflash the badly corrupted Bios chip.

So as said the in above photo shown Bios chip marked by a yellow-red arrow was removed, reflashed, and soldered back onto its mainboard position. Next screen copy shows the successfully programmed and verified MX25L1606E Bios chip done with the TL866 universal programmer.
After the Bios was flashed with the TL866 programmer and the right Bios file, the laptop was fixed and next screen shows the Windows 10 Pro configuration that was back as it was before the bad driver upgrade corrupted the Acer laptop. And I advised my brother to run the small 600kB “Universal BIOS Backup ToolKit 2.0” program tool to make an easy backup copy of his current now working Bios chip. And to do that also in all other cases before he upgrades any laptop or computer.
Next screen copy shows that handy Bios copier tool. It not always works but it most of the time recognizes the Bios and it saves the user having to open his laptop and having to remove that chip to backup and check its content.
The fact that the Bios USB flash bootstick didn’t boot was probably caused by the fact that the Samsung SSD software had changed the Laptop boot setup to AHCI, and Legacy or standard USB Boot no longer was used.
And many people with corrupted Bios Laptops/computers claim they tried anything to make and prepare this USB Bios bootstick but it never worked. Which could be caused by the wrong boot setup before the Bios crashed. So did we until we finally started to remove the Bios chip, flashed it externally, put it back, and found it completely fixed this way. We previously only noticed that the Led on our prepared USB Bios boot stick flashed about 6 times but nothing else happened.
This Acer 5560 Laptop didn’t have any sleep activating button but my brother noticed that when he closed the laptop screen it automatically went into sleep mode after which the most left orange front Led started to blink. Which at the same time prevented the blue Power On Led and the Fan from staying on when Windows 10 was closed down. And the same sleep mode was also activated by selecting the Windows sleep power mode. And it was switched back on within about a second from sleep mode. The Laptop as mentioned was only completely powered down after the Power button was pushed in for about 5 seconds. (Which normally only should be done by letting the Windows system switch off on its own to prevent any resulting powering down errors in the system on the harddisk later on).
According to my brother the Bios trouble all started after Windows 10 install kept on rebooting and it ended in the laptop being paused seemingly for hours when nothing was happening. Including a black screen that left only one option to reset and reboot the Windows 10 system again. Until it also completely failed to boot after it corrupted the Bios chip. One reason was that installing the Netframe 3.5 failed and had caused Windows to crash. But after the Bios chip was flashed with the right MX25L1606E Acer 5560 image my brother finally was able to install Windows 10 with Netframe 3.5 and its version 4.8 update. And the Acer 5560 Laptop no longer caused any Windows 10 problems. And next Base System driver problem was finally also fixed.
This driver problem previously couldn’t be fixed and the driver update that Windows 10 proposed made the Laptop’s Bios crash by corrupting its content:
failure (2x) in devices :
PCI-slot 4 (PCI-bus 1, device 0, functie 3
Device PCI\VEN_14E4&DEV_16BF&SUBSYS_06051025&REV_10\4&211965bf&0&0320 requires further installation.
So be warned to better make a copy of your Bios chip and/or Windows OS if you can, before any faulty Windows upgrade corrupts your computer’s Boot sequence and also your Bios chip!
