My T-453be died. Just a red led on front and lit network ports. No fan. No signs of life. Prior to this unit I had a T-251 that died I think the same way (but before this thread started). I ordered a returnable T-451D2 as means to quickly try to recover data from disks and use if resistor trick doesn’t succeed, but after reading more this seems like a model that will also die and better off avoided. Any suggestions for QNAP 4 bay models that are comparable price/features, that I could just migrate disks to? My alternative may just be to setup old Mac Mini with RAID disks cabinet (and load Plex,etc).

I’ve been messaging with QNAP support on the above and their latest reply follows. Does anyone have any info that discredits this? I”d love to point them to a specific customer/support ticket. My preference is to just replace failed unit with new, but don’t want to have a 3rd unit die at 2.5 years old. My alternate plan is to simply build Plex/Server using Mac Mini and RAID 5 storage cabinet (most cost, but likely more stable long term.

From Support:
I've brought this up to my senior and he looked at the forum post. He said the issue is relating to old 51/51+/53Pro series and not the x53Be as they use a different MB/CPU. It is not the same issue. The newer model x51 model NASes should not have this issue.

here is an article from wikichip outlining the LPC issue on Apollo Lake (Celeron J3455)

Do we need 1/4w or 1/2w?
There is very very small current (a few mA at max) flowing throught this resistor, so 1/4W is largely enough. You can also use 1/2W with no risk at all.

Code: Select all

Does the color matter? 
NO
Use Metal film resistor preferabily, but it is not a "critical" location, so this is not important.
Bonus points for link.
Here are some links, but remember that ANY 100 ohm resistor, 1/8W, 1/4W or 1/2W will be OK.
Choose the seller depending on the country you live (Europe ?, USA ?,...)
Some persons say that you can increase the resistor value up to 430 ohms in order to decrease the current (and therefore increase the working life of the "repaired" QNAP after this fix), but I have not yet tested it .

https://www.amazon.com/Tnisesm-Resistor ... B08BYK5FXN

What about connectors for those who don’t want to solder?
The simplest connector to use is a one pin DUPONT connector, like this one:
https://fr.aliexpress.com/item/32717763865.html
sold with the metallic insert.

Of course you need 2 Dupont connectors: one for each resistor leg.

It is not mandatory to solder the resistor to his metallic insert, it can be crimped: but you need a crimp tool (having a 1.6mm crimp size) to achieve that properly...


An alternative is to use a 2,54mm jumper like this one:
you should insert the resistor pin on the top of the jumper, and the other side of the jumper onto the QNAP connector: I am not 100% sure but this should established an "acceptable" contact without soldering.

Of course you 2 jumpers: one for each resistor leg.

In both cases, Keep the resistor legs short, and take care to not establish any contact with the non appropriate pins of the QNAP connector.

P.S.: if you live in Europe, send me a Private Message indicating your country.

not lucky !....

If larryebaum resides somewhere in Europe, I planned to post him a "ready to install resistor" witht he Dupont connectors already crimped, to help him (he will not have to solder anything)...

I know .. I have proposed these connector wires already several times in this thread and others dealing with this issue
