AceDaz Posted January 8, 2013 Posted January 8, 2013 We bought 22 of the above laptops in 2010, and I have been having a few unique faults with them. The latest being that Windows 7 reports that the laptop is "Plugged in, not charging". I have tried a replacement battery, different (original) power supplies, unplugging the battery in all sorts of combinations, removing the battery driver. All to no avail. The next step is to re-image the laptop. Has anyone got any other ideas? Thanks
Michael Posted January 8, 2013 Posted January 8, 2013 Are the notebooks using the default HP image or a custom image in the past?
AceDaz Posted January 8, 2013 Author Posted January 8, 2013 Are the notebooks using the default HP image or a custom image in the past? It is a custom Windows 7 Enterprise x64 image that has been running for many months, not all the HP 620 laptops currently have issues. There has been 4 out of 22 with this issue, another was with a screen.
Michael Posted January 8, 2013 Posted January 8, 2013 In that case I'd say just re-image those four notebooks.
AceDaz Posted January 8, 2013 Author Posted January 8, 2013 Can try it, but I don't hold out much hope I will let you know as they are teacher laptops

The battery I tried was taken out of a good known laptop that charged up...i never tried charging the other battery in the working one tho.......
jmak Posted January 8, 2013 Posted January 8, 2013 We bought 4 HP620s a couple of years ago. We had one total battery failure at 11.5 months and 2 more failed at 13 months. After some argument, HP replaced the batteries out of warranty. They were total sudden failures - you couldn't even boot the PC with the battery installed as it was drawing too much current trying to charge the battery. Teachers first noticed when they unplugged from the mains and the machine just stopped dead - no hibernation or Hdd parking. HP got me to install a proprietary battery analysis app to test to their standards before arranging the swap. Let me know if you want the link to the download. On that history I won't be buying HP laptops again. 1

jmak Posted January 9, 2013 Posted January 9, 2013 Here you go: HP Battery test utility I ended up paying a bit more for Dell as I won't buy HP again Yep - we have 5 year old Dells which look better than the 2 year old HPs. I've heard good things about Lenovos, so I'll have a look at those at BETT. 1
AceDaz Posted January 9, 2013 Author Posted January 9, 2013 Here you go: HP Battery test utility Thanks Yep - we have 5 year old Dells which look better than the 2 year old HPs. I've heard good things about Lenovos, so I'll have a look at those at BETT. Could you feed back? I have had a couple of Lenovo's but the support hasn't been very good on them
witch Posted January 9, 2013 Posted January 9, 2013 Spooky The first thing I saw when I got in yesterday was that a battery had failed in an HP620 Stupidly, I took it on trust - yes, I know, I know - and ordered a new one. Had to show the laptop owner something on it today so I plugged it in with no battery and it didnt work. Swapped the charger and it now does I had already ordered the battery and had to leave that school so a panicky call to Terry @millenium got the order stopped (bless him) I will do some swapping out tomorrow to find out what is going on. It also turns out that the teacher was pushing for a new battery really quickly (which is what made me just order it) because she didnt realise that the laptop would work happily without the battery as long as it had power! Now she knows that she isnt quite as worried. Strangely, the first thing at my other school this morning was two failed batteries (carefully cross checked with working chargers and known-good batteries)
AceDaz Posted January 9, 2013 Author Posted January 9, 2013 Seems to be a very common issue with the HP 620, I have 2 other laptops that needed new batteries. I hope it is just that otherwise they are faulty as well as I have already got the batteries
SYNACK Posted January 9, 2013 Posted January 9, 2013 Thanks Could you feed back? I have had a couple of Lenovo's but the support hasn't been very good on them You could buy lenovo or just buy the probook or elite book range of HP instead of the consumer grade disposable ice cream container series.
AceDaz Posted January 9, 2013 Author Posted January 9, 2013 You could buy lenovo or just buy the probook or elite book range of HP instead of the consumer grade disposable ice cream container series. Isn't the Probook double the price?
SYNACK Posted January 9, 2013 Posted January 9, 2013 Isn't the Probook double the price? But it lasts three times as long so it's actually cheaper, especially if you have the right suppliers who bring the cost down to about the same as the consumer grade stuff anyway.
sted Posted January 9, 2013 Posted January 9, 2013 lenovos are generally nice but the last lot i gave out in a schoolthe teachers hated as the trackpads are dire and youcant even turn them off in device manager so when typing the mouse pointer gets moved occasionally and just for a laugh this morning a hp620 that the battery clip has broken on so the battery wont stay in place so it cant charge selotaped it in lol
tech_guy Posted January 9, 2013 Posted January 9, 2013 I've got a 620 that randomly blocky pixellates the screen so it looks like you're using a Sinclair Spectrum. HP are puzzled and reinstalls and firmware updates haven't solved it yet.
jmak Posted January 9, 2013 Posted January 9, 2013 You could buy lenovo or just buy the probook or elite book range of HP instead of the consumer grade disposable ice cream container series. Agree it was probably a false economy, but they are marketed as business machines.
newpersn Posted January 27, 2015 Posted January 27, 2015 Sorry to drag a 2 year old post up, I got a 3 hp 620 that are refusing to charge. All doing this about the same time. I've ordered a replacement charger from amazon but till waiting for this to turn up. There no light on the side of the units when the lead is plugged in. 1 user told me he has to let his laptop die and then it will start charging the battery and be fine until the next unplugged. I'm currently looking for a bios update but dont want to do this on battery power... There are running a clean image of windows 7 ent. Any ideas?
jmak Posted January 27, 2015 Posted January 27, 2015 Sorry to drag a 2 year old post up, I'm currently looking for a bios update but dont want to do this on battery power... HP don't want you to do that either - the update won't run unless there's AC power connected. If you've got another unit, you could take the battery and the AC adaptor that you know to be good and try a BIOS update that way. I'm still nursing mine through, but won't be buying any more. These were never true enterprise grade units - the more expensive HPs have a good reputation, but these weren't much better than consumer grade.

About a week apart.... (all 3 laptops are now doing the same thing) I did a bios update once it was charged and still no change. Guessing the mainboard is die'ing slowly or charger about to give up.

This sounds like it could be a Tokin issue, is there a big squareish chip on the opposite side of the motherboard to the cpu ?

difinity Posted January 27, 2015 Posted January 27, 2015 It's a capacitor, the symptoms sound a little like the Toshibas of old that had charging/turning on problems with the charger in but ok on battery. In that instance it was removed and replaced with 4 330uf 2.5v tantalum caps.
