Bios Corrupt Asus K52 K53 K55 K56 After Updating Automatically Or Manually
Programming Or Replace The BIOS Chip
Some of the models Asus which applies this solution:
K53SV K53SD K53E K53SC K53U K53SJ K53SM K53BE K53SV K53E K53SD K53SM K53SJ K53SC K53BE K53BY K52JC K52JU K52JR K52DR K52F K52JB K52JE K52JK K55VD K55VJ K55DE K55A K55DR K55N K55VM K55VS And Many More ..
With the proposed solution it is possible to solve common problems with these models as Asus:
– ASUS K52 K53 K55 K56 Lights (Not Flash);
– ASUS K52 K53 K55 K56 Has Black Screen;
– Bios Corrupt ASUS K52 K53 K55 K56
I have gotten many models of Asus, all with the same problem: at any moment the ‘Asus K52, K53, K55, K56 stops start seems particularly after an automatic update BIOS .
Or after an attempt manual BIOS update (Flash Bios). No matter: the Asus K no longer starts.
How To Restore The BIOS Of ‘Asus Series K52 K53 K55 Or K56?
You may have read about some of the site recovery procedures Bios .
Perfect. Do not bother with: format USB keys, insert files Bios appropriately renamed, press key combinations special NOT SERVE ‘NOTHING THIS TIME (unfortunately).
Why? On other occasions and with other PC recovery BIOS is possible with USB drives, Floppy or CD properly prepared and a simple key combination pressed when the PC; in other cases it is necessary also short some points on motherboards or disconnect the battery CMOS backup (the case of some Toshiba).
But in this case , with these Asus, NO: it will not work any of this.
What Is The Solution Then To Recover These Series Asus K56 K55 K53 K52 ??
There is a solution but it is not for everyone: it is to replace the EEPROM chip , which is the model Winbond W25Q64 (or similar)with a new one and then program it with a version of BIOS compatible with your motherboard.
The problem is known to Asus it is under warranty until the parent returns smoothly the Bios Series K55 K56 K53 K52. This happens because this anomaly with the Bios is unclear: it may be the component to be defective or update mechanism for Windows 8 that lets you manage and update the BIOS directly.
The fact is that in most cases they are not even able to reprogram the original chip with EEPROM programmer, a sign that there is some defect (not detected by the software programming).
All that remains is to mount a chip of the family Winbond W25Q64 (eg W25Q64FV ) brand new course previously programmed with a programmer similar to that in the following picture:
I personally have a very versatile professional programmer: TL866A. With adapters and clips can be programmed around.
The model I repaired in this article is an Asus motherboard with K56CM. The abbreviation is present as screen printing on the motherboard and also on the label
The Asus K56 CM object of this repair is a relatively recent model, mounts I5 CPU and a GPU nVidia GeForce GT 635m.Obviously, there are various versions of this model, with I7 processor.
The following picture is a model of Asus K56 CPU I7:
We begin to dismantle the machine to get to the BIOS chip soldered on the bottom of the motherboard.
Remove this Asus K56CM is really simple because its architecture is trivial. We have to unscrew a few screws and remove the plastic shell; then we can Employment on the motherboard.
We begin with the unscrew the 3 screws of the large lid and rimuoviamlo by sliding. This hides the hard drive and RAM.
Remove all screws, even those that secure the hard disk. And let’s remove it of course …
Then it’s up to the writer-DVD player ..
After removing all the screws we use a tool to separate the plastic from the rest of the body below the top.
After removing the body can get the mother of ‘ A sus K56 CM:
We remove all the screws holding the motherboard to the top then we disconnect all cables and flat.
Then we raise slightly the motherboard on one side, without removing it completely as there are two other flat to detach, what the keyboard and that to which the ticket side (USB and audio jacks). Be gentle when you disconnect everything and above all ….remember to reattach connectors and flat during assembly.
The flat black is to disconnect the keyboard.
Near the CMOS backup battery are the EEPROM Winbond W25Q64 defective. This is formed by a SMD with 8-pin, 4 on each side. There are many variations of EEPROM, shape and capacity (memory) different.
At this point I have two options:
– Write the BIOS software directly on the chip without desoldering or replace it (not recommended);
– program a new BIOS chip and solder it in place of the (recommended);
We see the first possibility: attack the programmer, apply the clip to the EEPROM, the backup battery detachment (which is recommended), run the program and try to program the EEPROM ..
Then I select the right component, the correct BIOS file and septum some settings … then start erasing and writing of memory …
The process of writing obviously not work if the component is defective. Then you just have to try the other procedure, tocomplete replacement of the component .
The first thing to do is to program the chip again. To do well to procure the component must have the right programming interface that is a PLCC adapter for our pinout.
… And that in the next photo is the right one for our silicon chip ..
Some might ask: why not before we replace the chip and then after we program easily with the clip as seen before?
Better not: in fact often are unable to program the chip when soldered on the motherboard, the programming can highlight errors .. to avoid problems so better schedule it before.
The software provides us with guidance on how to place the component on the panel of the programmer ..
Then insert the chip in the adapter BIOS, load the correct firmware and start programming.
Under the new chip Winbond W25Q64 bios beside the defective before removal work.
To remove the component can act with hot air or with classic soldering iron, always helping with the dough firm.
After removing the component you make a clean tracks then proceed to the fixing of the new EEPROM.
And here’s the result: component welded .. but funzionarà then ?? We must continue to mount and the Asus ..
I do a first test result …?
Asus K56CM With The New Bios Lights !!
I try to set some information such as date and time, to save and reboot: lights without problems!
Complete closure of ‘Asus K56CM and I perform other tests …
The problem with the bios dell’Asus K56CM is only a distant memory!
If you also have a Asus K52 K55 K56 K53a with startup problems caused by Bios corrupt and need assistance please contact me!
