I feel the need to jump in here and post a warning about buying a new power jack for your N53-SV as I have bought one that was labeled N53-JN DC BOARD and this did not match the old board AT ALL in terms of the smc parts on the board. I excluded sowtware reasons since I anyway set bios to defaults and ran recovery to fully reset the system.ĭoes anyone have an idea what that could be? I tried another AC adapter just for case but the result is the same, so it's not the adapter I take it. The PC runs on the battery, but I didn't try too much since it doesn't charge.

The AC adpter looks fine, pc works without battery and the battery doesn't discharge while running with adaper switched ON. So I bought a new one and was surprised because it won't charge again! So I gave the battery to the the local tech's so they try to charge it with a special device (dont remmmbr name) but they failed and told me the battery is apparently dead. I thought the problem was the deep discharge of the battery after which it doesn't charge with a standart adapter. At that point, once you pull out AC adapter, the notebook immediately switched off. After I switched it on, the battery showed 0% and didn't charge. To me the problem apppeared after I left the notebook in Sleep mode for ~2 weeks. I have absolutely the same issue as the author of the thread. A generic charger company on the other hand does not care after they your money.įor the third time, take the battery out of the laptop with it still plugged into the ac power cord, and see if tht works

The OEM has to warranty the laptop so the last thing they are going to do is use a cheap adapter that will fry the laptop (lets not bring up HP here). I own a small PC repair business and I have seen many many laptops (and batteries) destroyed by these generic 'replacement' chargers. Only ever get OEM or the brand that makes the OEM batteries, in the case of ASUS that is Delta. Now the aftermarket ones can usually be had for 1/3 to 1/2 the price so can be a better buy then OEM (but it is still a risk)

In regards to aftermarket batteries, some can be garbage but most will work just fine they do have a quicker decay rate (so if it took 2 years for your OEM to have less charge, then aftermarket might only take 1 to 1-1/2 years). For longest performance, this is usually the best option. OEM is always going to be a known variable because that is what is your laptop came with and you know how it performs. My take on replacement batteries and ac chargers: You can order a new jack on amazon for $5-10, but unless you are very good with soldering iron and desoldering you will need to take it to an electronics repair shop. Without being able to actually inspect your laptop, my thought would be that your DC jack has a small fracture in it (possibly too small to see with untrained eyes).
