content: Hi all,first I wish everybody a good and healthy new year 2025!Unfortunately for me it began with some trouble:Yesterday after switching on my Siglent SHS810X portable Scope which was off during a longer period (~ a few weeks) everything still seemed to be fine...After switching on for taking some measurements it switched off after approximately 10 seconds.There was no red power button led! After switching to on it was green.I thought that the LiION battery must be empty and plugged in the power supply. But it does no longer switched on. It was green after plugin of the power supply.After some time it began blinking alternately green and orange.I decided to charge the battery overnight and continue the next day.Today morning I looked at the charge state but I see the power button led still blinking green and orange. This seemed strange to me.After pulling out the battery and take a quick voltage measurement it gave only 1.24 volts alternating with 0.99 volts. No fixed voltage.So now I have some questions:- it seems that the battery is damaged? (because of the too low voltage level - but the scope was new and I got it in 09-2024)- is there a blink code list of the power button led? (I do not found some infos in the manuals or here in the forum)I cannot open the scope because I do not want to risk the warranty.So only the exchange of the battery will be possible but I am afraid that if there is some defect inside I will damage a new battery too...Cheers Chris

content: Quote from: dekagon on January 03, 2025, 09:35:25 amHappy New Year!My advice, start warranty claim with company you purchased it from.They will sort out if it is battery alone or scope or something else. Start claim ASAP so it can be resolved sooner.Do not tamper with it.In cases like these, manufacturers might want to investigate causes.So less you try to repair something is better for further detective work.Good luck.

content: I agree with 2N3055 that you should claim warranty, but here are some observations with a SHS1000X (same platform as SHS800X):When I remove the battery and insert the charger, the power LED blinks alternating green and orange. So this seems to indicate a problem with the battery.With the battery removed and the charger still attached, the device powers up normally after pressing the power button. The battery status icon in the top right corner shows an empty red battery with exclamation mark in it.

content: @2N3055, @mahi,thank you for your replies.I think that there must be a defect with the scope because when I plug in the power supply without battery the power button led first turns green and after a moment it is blinking green / orange.That is what I observed.The scope do not let me switch on with the power supply connected alone.Does this mean I have to send it to my seller company?I bought this from Batronix in September. It was the last available one...Cheers Chris

content: I didn't see another thread for the SHS810x, so posting here.For ch1, the menu is missing the probe type all of a suden. There is a blank menu where the probe selection should be. Pressing the function button, under the blank, allows me to select the probe. Changing to ch2 and the menu is correct. Bug?Jerryrebooting corrects it.

content: The main thread for support of these handheld scopes is here:https://www.eevblog.com/forum/testgear/new-x-model-siglent-handhelds-coming/It would be best to post this bug report on that thread so others can comment.*** edit: I can see that you have been posting on the other thread, but not for this report? ***
